Physical Disintegration of Biochar: An Overlooked Process
Provedor de dados: 18
Autores: Spokas, K.A.; Novak, J.M.; Masiello, C.A.; Johnson, M.G.; Colosky, E.C.; Ippolito, J.A.; Trigo, C.
Data collected from both artificially and field (naturally) weathered biochar suggest that a potentially significant pathway of biochar disappearance is through physical breakdown of the biochar structure. Through scanning electron microscopy (SEM) we characterized this physical weathering which increased structural fractures and possessed higher numbers of liberated biochar fragments. This was hypothesized to be due to the graphitic sheet expansion accompanying water sorption coupled with comminution.  These fragments can be on the micro and nano-scale, but are still carbon-rich particles with no detectable alteration in the oxygen to carbon ratio of the original biochar. However, these particles are now easily dissolved and could be moved by...

Clinoptilolite Zeolite Influence on Inorganic Nitrogen in Silt Loam and Sandy Agricultural Soils
Provedor de dados: 18
Autores: Tarkalson, D.D.; Ippolito, J.A.
Development of best management practices can help improve inorganic nitrogen (N) availability to plants and reduce nitrate-nitrogen (NO3-N) leaching in soils.  This study was conducted to determine the influence of the zeolite mineral Clinoptilolite (CL) additions on NO3-N and ammonium-nitrogen (NH4-N) in two common Pacific Northwest soils.  The effects of CL application rate (up to 26.9 Mg ha-1) either band applied or mixed with a set rate of nitrogen (N) fertilizer on masses of NO3-N and NH4-N in leachate and soil was investigated in a column study using a Portneuf silt loam (coarse-silty mixed mesic Durixerollic Caliciorthid) and a Wolverine sand (Mixed, frigid Xeric Torripsamment).  All treatments for each soil received a uniform application of N from...

Contrasting effects of biochar versus manure on soil microbial communities and enzyme activities in an Aridisol
Provedor de dados: 18
Autores: Elzobair, K.A.; Stromberger, M.E.; Ippolito, J.A.; Lentz, R.D.
Biochar has been shown to increase microbial activity, alter microbial community structure, and increase soil fertility in arid and semi-arid soils, but at relatively high rates that may be impractical for large-scale field studies. This contrasts with organic amendments such as manure, which can be abundant and inexpensive if locally available, and thus can be applied to fields at greater rates than biochar. In a field study comparing biochar and manure, a fast pyrolysis hardwood biochar (10 tons per acre), dairy manure (19 tons per acre), a combination of biochar and manure at the aforementioned rates, or no amendment (control) was applied to an Aridisol (n=3) in fall 2008. Plots were annually cropped to corn.  Surface soils (0-12 inches) were sampled...

Soil phosphorus availability differences between sprinkler and furrow irrigation
Provedor de dados: 18
Autores: Ippolito, J.A.; Bjorneberg, D.L.
Water flowing in irrigation furrows detaches and transports soil particles and subsequently nutrients such as phosphorus.  To reduce the risk of erosion and offsite phosphorus transport, producers in south-central Idaho have been converting from furrow to sprinkler irrigation.  We completed research on soil phosphorus dynamics in furrow versus sprinkler irrigated soils from four paired-fields in the region.  Surface soils (0-2.5 inches) were obtained from fields in September following barley harvest.  Furrow irrigated soils contained 38 parts per million of plant-available phosphorus (i.e. Olsen-extractable), on average, as compared to 20 parts per million under sprinkler irrigation.  These results are important as 20 parts per million extractable...

Stabilizing effect of biochar on soil extracellular enzymes after a denaturing stress
Provedor de dados: 18
Autores: Elzobair, K.A.; Stromberger, M.E.; Ippolito, J.A.
Stabilization of extracellular enzymes may maintain enzymatic activity for ecosystem services such as carbon sequestration, nutrient cycling, and bioremediation, while protecting enzymes from proteolysis and denaturation. A laboratory incubation study was conducted to determine whether a fast pyrolysis biochar (CQuest) derived from oak and hickory hardwood would stabilize extracellular enzymes in soil and prohibit the loss of potential enzyme activity following a denaturing stress, in this case microwaving. Soil was incubated in the presence of biochar (0, 1, 2, 5, or 10% by weight) for 36 days and subsequently exposed to microwave energies of 0, 400, 800, 1600, or 3200 Joules per gram of soil.

Development of vegetation based soil quality indices for mineralized terrane in arid and semi-arid ecosystems.
Provedor de dados: 18
Autores: Blecker, S.W.; STILLINGS, L.L.; MCAMACHER, M.C.; Ippolito, J.A.; DECRAPPEO, N.M.
Soil quality indices are often management driven and attempt to describe key relationships between above- and below-ground parameters.  In terrestrial systems, indices that were initially developed and modified for agroecosystems have been applied to non-agricultural systems in increasing number. We developed a soil quality index in arid and semi-arid ecosystems of the Western US impacted by different types of geologic mineralization using the relationship between vegetation community parameters and soil abiotic and biotic properties. We analyzed these relations in soils associated with three different mineralization types: podiform chromite, Copper/Molybdenum porphyry, and acid-sulfate gold vein systems at four different sites in California and Nevada....

Revegetation of Fluvial Mine Tailing Deposits: The Use of Five Riparian Shrub Species
Provedor de dados: 18
Autores: Davis, N.; Meiman, P.; Brummer, J.; Ippolito, J.A.
Fluvial deposition of mine tailings has caused extensive damage to riparian ecosystems throughout the West. Willows are often used for revegetation of fluvial mine tailing deposits but some species accumulate toxic concentrations of metals in leaves and stems. A greenhouse experiment was conducted to determine the value of thinleaf alder [Alnus incana (L.) Moench spp. tinuifolia (Nutt.) Breitung], water birch (Betula occidentalis Hook.), red osier dogwood (Cornus sericea L. spp. sericea), and shrubby cinquefoil [Dasiphora fruticosa (L.) Rybd.] compared to Geyer willow (Salix geyeriana Andersson) for revegetation of fluvial tailing deposits along the Upper Arkansas River. Bare root shrubs were grown in tailings amended with lime and composted biosolids....

Hardwood biochar influences calcareous soil physicochemical and microbiological status
Provedor de dados: 18
Autores: Ippolito, J.A.; Stromberger, M.E.; Lentz, R.D.; Dungan, R.S.
The effects of biochar application to calcareous soils are not well documented. In a laboratory incubation study, a hardwood-based, fast pyrolysis biochar was applied (0, 1, 2, and 10% by weight) to a calcareous soil. Changes in soil chemistry, water content, microbial respiration, and microbial community structure were monitored over a 12-month period. Increasing biochar application rate increased the water holding capacity of the soil-biochar blend, a trait that could be beneficial under water limited situations. Biochar application also caused an increase in plant-available iron and manganese, soil carbon content, soil respiration rates, bacterial populations, and a decrease in soil nitrate-nitrogen concentration. Biochar rates of 2 and 10% altered the...

Biosolids Application to No-Till Dryland Agroecosytems
Provedor de dados: 18
Autores: Ippolito, J.A.; Barbarick, K.A.; McDaniel, J.P.; Hansen., N.C.; Peterson, G.A.
Dryland agroecosystems are generally ideal environments for recycling biosolids.  However, what is the efficacy of biosolids addition to a no-till dryland management agroecosystem?  From 2000 to 2010, we studied application of biosolids from the Littleton/Englewood, CO Wastewater Treatment Plant versus commercial nitrogen fertilizer in dryland no-till wheat (Triticum aestivum, L.)-fallow (WF) and wheat-corn (Zea mays, L.)-fallow (WCF) rotations at a site approximately 50 miles east of Denver, CO.  We tested if biosolids would produce the same yields and grain phosphorus, zinc, and barium concentrations as an equivalent rate of nitrogen fertilizer, that biosolids-borne phosphorus, zinc, and barium would not migrate below the 4 inch soil depth, and that...

Biochar elemental composition and factors influencing nutrient retention
Provedor de dados: 18
Autores: Ippolito, J.A.; Spokas, K.A.; Novak, J.M.; Lentz, R.D.; Cantrell, K.B.
Biochar is the carbonaceous solid byproduct of the thermochemical conversion of a carbon-bearing organic material, commonly high in cellulose, hemicelluloses, or lignin content, for the purposes of carbon sequestration and storage.  More specifically, the thermal conversion process known as pyrolysis occurs when carbon-containing substances are introduced to elevated temperatures in the absence of oxygen at varying residence times, yielding biochar.  Several pyrolysis techniques employed to produce biochar differ in the temperature of reaction and residence time in the reactor.  Different reactor residence times are described as slow (hours to days), fast (seconds to minutes), and flash (seconds).  Fast or flash pyrolysis typically occurs around 500oC with...

Droughts associated with low or erratic rainfall distribution can cause detrimental crop moisture stress. This problem is exacerbated in the USA’s arid western and southeastern Coastal Plain due to poor rainfall distribution, poor soil water storage, or poorly-aggregated, subsurface hard layers that limit root penetration. We hypothesized that soil physical deficiencies may be improved by biochar applications. Research indicates a single biochar will not serve as a universal supplement to all soils; consequently, biochars may need to be designed with physico-chemical properties that can ameliorate specific soil physical deficiencies. We conducted a laboratory study that examined the effect of biochar on soil moisture retention and aggregate formation....

Waste molding and core sands from the foundry industry have been successfully used around the world as byproducts in geotechnical and agricultural applications.  Although waste foundry sands (WFSs) are generally not considered hazardous in nature, relevant data are not available in Argentina.  This study aimed to quantify metals in waste molding and core sands from foundries using a variety of metal-binder combinations.  Metal concentrations in WFSs were compared to those in virgin silica sands (VSSs), surface soil and soil guidance levels according to hazardous waste law 24.051 from the Argentinean Secretariat of Environment and Sustainable Development.

Regression modeling weather and biolsolids effects on dryland wheat yields in Eastern Colorado, 2001-2012
Provedor de dados: 18
Autores: Barbarack, K.A.; Ippolito, J.A.; McDaniel, J.P.; Hansen., N.C.; Peterson, G.A.
In the western Great Plains, climate dictates dryland wheat (Triticum aestivum, L) productivity. Producers use inorganic N fertilizers to improve crop yields in this region, while municipalities recycle sewage biosolids in the area. Will biosolids (from the Littleton/Englewood, CO Wastewater Treatment Plant) applications to western Great Plains dryland agroecosystems interact with weather to affect wheat production? To this end, we regressed crop yields on weather variables from 2000 through 2011 at a site about 40 km (approximately 25 miles) east of Byers, CO (Byers). We used SAS (Proc Reg) to develop several multiple regression models to predict crop yields. Our model of choice included four weather parameters for Byers wheat production. Regression...

Aluminum-based water treatment residuals (Al-WTR) have a strong affinity to sorb phosphorus.  In a proof-of-concept greenhouse column study, Al-WTR was surface-applied at 0, 62, 124, and 248 Mg/ha to 15 cm of soil on top of 46 cm of sand; Al-WTR rates were estimated to capture 0, 10, 20, and 40 years of phosphorus from an urban watershed entering an engineered wetland in Boise, Idaho, USA.  Creeping red fescue (Festuca rubra) was established in all columns; one set of columns received no Al-WTR or plants.  After plant establishment, once per week over a 12-week period, ~1.0 pore volumes of ~0.20 mg phosphorus/L was added to each column.  Infiltration rates were measured, leachate was collected and analyzed for soluble phosphorus, and fescue yield,...

Autores: Bjorneberg, D.L.; Ippolito, J.A.; Koehn, A.C.
Water, sediment and nutrients flowing into and out of the 82,000 ha Twin Falls,ID irrigation tract were measured from 2005 to 2008. Approximately 80% of the water flowing into the watershed was irrigation water diverted from the Snake River. About 40% of the watershed inflow returned to the Snake River. Much of this return flow was water from subsurface drain tiles and tunnels that drain shallow groundwater. Converting from furrow to sprinkler irrigation, improved irrigation management, and constructed sediment ponds have reduced sediment loss from 460 kg/ha in 1971 to &lt;100 kg/ha in 2005. In 2007 and 2008, more sediment and phosphorus entered the watershed than returned to the Snake River. Diverting irrigation water into the watershed removed 6300 Mg of...

Irrigated silage corn is the main crop used for phosphorus removal; however little is known about the actual amounts of phosphorus removed under southern Idaho growing conditions. The purpose of this study was to survey phosphorus removal by irrigated corn grown for silage in southern Idaho under variable soil test phosphorus concentrations. In this survey whole plant corn tissue phosphorus concentrations ranged from 0.116 to 0.307% total phosphorus and averaged 0.208%, which is lower than Natural Resources Conservation Services estimates used prior to 2007 (0.26% phosphorus) but higher than estimates used since 2007 (0.185%).  The study was used by NRCS to update nutrient management planning software used by planners in Idaho.

Sulfate Foot Baths on Dairies and Crop Toxicities
Provedor de dados: 18
Autores: Moore, A.; Ippolito, J.A.
A rising concern with the application of dairy wastes to agricultural fields is the accumulation of   copper (Cu) in the soil. Copper sulfate (CuSO4) from cattle footbaths is washed out of dairy   barns and into wastewater lagoons. The addition of CuSO4 baths can increase Cu concentration   significantly in manure slurry, from approximately 5.0 grams per 1,000 liters to 90.0 grams per   1,000 liters. The Cu-enriched dairy waste is then applied to agricultural crops, thus raising   concerns about how soils and plants are impacted by these Cu additions.

Autores: Lentz, R.D.; Ippolito, J.A.; Spokas, K.A.
Few multiyear field studies have examined the impacts of a one-time biochar application on net N mineralization and greenhouse gas emissions in an irrigated, calcareous soil; yet such applications are hypothesized as a means of sequestering atmospheric CO2 and improving soil quality.  We fall-applied four treatments, stockpiled dairy manure (42 Mg/ha dry wt.); hardwood-derived biochar (22.4 Mg/ha); combined biochar and manure; and no amendments (control).  Nitrogen fertilizer was applied in all plots and years based on treatment’s pre-season soil test N and crop requirements, and accounting for estimated N mineralized from added manure.  From 2009 to 2011 we measured greenhouse gas fluxes using vented chambers, net N mineralization (NNM) using buried bags,...

Soil P transformations and distribution studies under water limited conditions that characterize many grasslands may provide further insight into the importance of abiotic and biotic P controls within grassdominated ecosystems. We assessed transformations between P pools across four sites spanning the shortgrass steppe, mixed grass prairie, and tallgrass prairie along a 400-mm precipitation gradient across the central Great Plains. Pedon total elemental and constituent mass balance analyses reflected a pattern of increased chemical weathering from the more arid shortgrass steppe to the more mesic tallgrass prairie. Soil surface A horizon P accumulation was likely related to increased biocycling and biological mining. Soluble P, a small fraction of total P...

The use of biochar has received growing attention with regards to improving the physico-chemical properties of highly weathered Ultisols and Oxisols, yet very little research has focused on effects in Aridisols.  The objective of this study was to investigate the effect of either low or high temperature (250 or 500C) pyrolyzed switchgrass biochar on two Aridisols.  In a pot study, biochar was added at 2% w/w to either a Declo loam (Xeric Haplocalcids) or a Warden very fine sandy loam (Xeric Haplocambids) and then incubated at 15% moisture content (by weight) for 127 days; a control (no biochar) was also included.

Uptake coefficients for biosolids-amended dryland winter wheat
Provedor de dados: 18
Autores: Barbarack, K.A.; Ippolito, J.A.; McDaniel, J.
Biosolids regulations developed in the United States employed risk assessment impacts of trace element additions on plant uptake.  The US Environmental Protection Agency adapted the uptake coefficient (ratio of plant concentration to quantity of element added) when developing limitations on selected elemental additions.  The nature of the risk assessment requires uptake coefficients to be constants.  Our hypothesis was the uptake coefficient for copper, iron, molybdenum, nickel, phosphorus, and zinc for biosolids-amended dryland winter wheat decreases with multiple biosolids applications at the same location.  We applied up to 10 applications to two sites (designated North Bennett A and B) in eastern Colorado at rates from 2.24 to 11.2 megagrams per...

A rising concern with the application of dairy wastes to agricultural fields is the accumulation of copper in the soil. Copper sulfate from cattle footbaths is washed out of dairy barns and into wastewater lagoons. Potato growers are concerned about this issue, as many of the predominant dairy producing areas in Southern Idaho are also in Idaho’s established potato production regions. The objective of this project was to evaluate potato growth and copper plant uptake for potatoes grown under low, moderate, and excessively high soil copper concentrations. This study was conducted in 2011 in a greenhouse setting at the USDA ARS Kimberly Research Station. To establish an effective copper response curve, 6 rates of copper sulfate (0, 100, 200, 300, 400, and...

Provedor de dados: 18
Autores: Ippolito, J.A.; Ducey, Tom; Tarkalson, D.D.
Copper sulfate foot baths are a management practice used by dairy farms in an effort to control hoof infections. As an unintended consequence, agricultural soils experience Cu accumulation when spent foot baths are disposed of in wastewater lagoons that are utilized for irrigation purposes.  We investigated the effect of Cu applications (up to 1000 mg/kg) to a Xeric Haplocalcid (Declo series) and a Typic Calciaquoll (Logan series) on alfalfa (Medicago sativa) growth and Cu concentration, soil total and diethylenetriaminepentaacetic acid (DTPA)-extractable Cu, and the soil microbial community diversity using ribosomal intergenic spacer analysis (RISA).  Copper application up to 250 mg/kg did not affect alfalfa growth; above 500 mg/kg alfalfa did not grow....

Dairy manure field applications-How much is too much?
Provedor de dados: 18
Autores: Moore, Amber; Ippolito, J.A.
Applying dairy manure to agricultural fields has  been shown to increase crop yields, improve the  water-holding capacity of the soil, and enhance  soil fertility. However, when manures are applied  to fields at high rates over a period of several  years, nutrients can accumulate, causing  eutrophication in drainage waterways; degradation  of drinking water; nutrient toxicities in plants;  nutrient deficiencies in plants; disruptions in  soil microbial populations; and nutritional   imbalances for grazing animals. Growersand dairy   producers also run the risk of violating state and   federal regulations designed toavoid these issues.

Investigation of copper sorption by sugar beet processing lime waste
Provedor de dados: 18
Autores: Ippolito, J.A.; Strawn, D.G.; Scheckel, K.G.
In the western US, sugar beet processing for sugar recovery generates a lime-based waste product (~250,000 megagrams/yr) that has little liming value in the region’s calcareous soils.  This area has recently experienced an increase in dairy production, with dairies utilizing copper-based hoof baths to prevent hoof diseases.  A concern exists regarding soil copper accumulation as spent hoof baths may be disposed of in waste ponds with pond waters utilized for irrigation.  The objective of this preliminary study was to evaluate the ability of lime waste to sorb copper.  Lime waste was mixed with increasing copper-containing solutions (up to 100,000 mg/kg), at various buffered pH values (6, 7, 8, 9), and shaken over various time periods (up to 30 days)....

Autores: Ippolito, J.A.; Strawn, D.G.; Scheckel, K.G.; Novak M, J; Ahmedna, M.; Niandou, M.A.S.
Excessive copper concentrations in water systems can negatively impact biological systems.  Because copper can form strong associations with organic functional groups, we examined the ability of biochar (a carbon-enriched organic bioenergy by-product) to sorb copper from solution.  In a batch experiment, potassium hydroxide-steam activated pecan shell biochar was shaken for 24 hours in pH 6, 7, 8, or 9 buffered solutions containing various copper concentrations to identify effect of pH on biochar copper sorption.  Afterwards, all biochar solids from the 24 hours shaking period were air-dried and then analyzed using X-ray absorption fine structure spectroscopy to determine solid-phase copper speciation.  In a separate batch experiment, biochar was shaken...

Organic Waste Nitrogen and Phosphorus Dynamics Under Dryland Agroecosystems
Provedor de dados: 18
Autores: Ippolito, J.A.; Barbarick, K.A.
Organic waste beneficial-use programs effectively recycle plant nutrients when applied at agronomic rates. Plant-nutrient availability, transport, and fate questions have arisen when organic wastes such as biosolids have been applied to dryland agroecosystems. What is the Nfertilizer equivalency of biosolids? What is the N mineralization rate of biosolids over periods of excess moisture or drought, and over long periods of time? Would biosolids, applied at an agronomic N rate for dryland winter wheat (Triticum aestivum L.), oversupply P? If overapplication occurred, what would the repercussions be in terms of excess soil P? Our objectives were to determine: biosolids N fertilizer equivalency; biosolids N mineralization during years of above and below...

Soils developed on relict hydrothermally altered soils throughout the Western United States present unique opportunities to study the role of geology on above and belowground biotic activity and composition. Soil and vegetation samples were taken at three unaltered andesite and three hydrothermally altered (acid-sulfate) sites located in and around Lassen Volcanoes National Park in northeastern California. In addition, three different types of disturbed areas (clearcut, thinned, pipeline) were sampled in acid-sulfate altered sites. Soils were sampled (0 to 15 centimeters) in mid-summer 2010 from both under-canopy and between-canopy areas within each of the sites. Soils were analyzed for numerous physical and chemical properties along with soil enzyme...

Addition of activated switchgrass biochar to an aridic subsoil increases microbial nitrogen cycling gene abundances
Provedor de dados: 18
Autores: Ducey, Tom; Ippolito, J.A.; Cantrell, K.B.; Novak, J.M.; Lentz, R.D.
It has been demonstrated that soil amended with biochar, designed specifically for use as a soil conditioner, results in changes to the microbial populations that reside therein. These changes have been reflected in studies measuring variations in microbial activity, biomass, and community structure. Despite these studies, very few experiments have been performed examining microbial genes involved in nutrient cycling processes. Given the paucity of research in this area, we designed a six-month study in a Portneuf soil (coarse-silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid) treated with three levels (1%, 2%, and 10% w/w ratio) of a biochar pyrolyzed from switchgrass (Panicum virgatum) at 350°C and steam activated at 800°C to measure the...

Drinking Water Treatment Residuals:  A Reveiw of Recent Uses
Provedor de dados: 18
Autores: Ippolito, J.A.; Barbarick, K.A.; Elliot, H.A.
Coagulants such as alum, [Al2(SO4)3X14H2O], ferric chloride [FeCl3], or ferric sulfate [Fe2(SO4)3] are commonly used to remove particulate and dissolved constituents from water supplies in the production of drinking water.  The resulting waste product, called water-treatment residuals (WTR), contains precipitated Al and Fe oxyhydroxides resulting in a strong affinity for anionic species.  Recent research has focused on using WTR as cost-effective materials to reduce soluble phosphorus (P) in soils, runoff, and land-applied organic wastes (manures and biosolids).  Studies show P adsorption by WTR to be fast and nearly irreversible, suggesting long-term stable immobilization of WTR-bound P.  Because excessive WTR application can induce P deficiency in crops,...

Magnesium phosphates such as struvite (MgNH4PO4x6H2O) can be recovered from municipal, industrial and agricultural wastewaters.  However, minimal research has been conducted on the beneficial reuse of these recovered products; conducted research has focused on low pH soils.  This study determined whether recovered struvite and dittmarite (MgNH4PO4xH2O) were effective P fertilizers in alkaline soils.  In addition to commercially available triple superphosphate (TSP) and certified organic rock phosphate (RP), recovered struvite, dittmarite, and a heterogeneous recovered phosphate were evaluated in a laboratory dissolution study and as fertilizers for spring wheat (Triticum aestivum L.) in a greenhouse study.  Struvite and dittmarite were much more soluble...

Soil quality indices provide a means of distilling large amounts of data into a single metric that evaluates the soil’s ability to carry out key ecosystem functions. Primarily developed in agroecosytems, then forested ecosystems, we set out to develop and apply an index using the relation between soil organic matter and key soil abiotic and biotic properties in more semi-arid of the Western US arid systems impacted by different geologic mineralization types. We studied these relations in three different mineralization types: serpentine, acid sulfate and Cu/Mo porphyry systems at four different sites in California and Nevada. Soil samples were collected from undisturbed soils in both mineralized and nearby unmineralized terrane as well as waste rock and...

Removal of vegtative clippings reduces dissolved phosphorus loss in runoff
Provedor de dados: 18
Autores: Ippolito, J.A.; Spackman, R.; Entry, J.A.; Sojka, R.E.
Phosphorus-containing sediment entering surface water may degrade water quality and promote eutrophication.  Grass is sometimes planted as a vegetated filter strip buffer along vulnerable receiving water to trap sediment and reduce the severity of phosphorus nutrient loading.  However, eutrophication is still a problem in some waterways due to dissolved phosphorus leaching from senesced vegetation in grassed areas, independent of trapped sediment.  A rainfall simulator (96 mm/h) was used to study the vegetative conditions under which losses of total dissolved phosphorus and filterable reactive phosphorus leaching are likely.  Boxes containing a Portneuf silt loam soil (Xeric Haplocalcid) were planted with annual ryegrass (Lolium perenne) and cut at two...

Autores: Miguel, Roberto E.; Ippolito, J.A.; Noriega, Roxana B; Dungan, R.S.
As part of the casting process, foundries create sand molds and cores to produce ferrous and non-ferrous metal castings.  After the process, a portion of the sand is discarded and becomes waste foundry sand (WFS). The aim of this study was to quantify metals (i.e. Ag, Ba, Cd, Cr, Cu, Ni, Pb, and Zn) in leaching extracts from a variety of waste molding and core sands from ferrous and non-ferrous foundries using the Extraction Procedure, Toxicity Characteristic Leaching Procedure, and ASTM water extraction procedure. The WFS metal extract concentrations were compared to those found in virgin silica sands and Argentinean and U.S. hazardous waste laws to determine if the WFSs met toxicity limits. The majority of the WFS extracts analyzed, regardless of metal...

Amending soil with biochar may be a means of sequestering atmospheric CO2 and improving soil quality, but few multiyear field studies have examined the impacts of a one-time biochar application in an irrigated, calcareous soil. We fall-applied four treatments: dairy manure (18.7 tons/ac dry wt.); hardwood-derived biochar (10 tons/ac dry wt.); combined biochar and manure; and no amendments (control). We measured net N-mineralization using buried soil bags and soil greenhouse gas emissions (CO2, CH4, and N2O) from late spring to fall, corn silage yields, and crop N uptake each year. The influence of biochar and manure on silage yield changed with time after application in fall 2008. Biochar increased corn yields slightly (5%) in 2009, decreased yields by 14%...

Soil fertility benefits of charcoal application have been reported as early as 1847 indicating that plant nutrients are sorbed within charcoal pores.  The use of biomass-derived black carbon or biochar, the solid byproduct from the pyrolysis processing of any organic feedstock, has garnered recent attention as a potential vehicle for carbon sequestration and a beneficial soil conditioner.  However, most of the past biochar research has focused on improving the physico-chemical properties of tropical (i.e. terra preta) and highly weathered soils, while little research has focused on improving arid or semi-arid soils of the USA.

Biochar can positively influence soil moisture relations
Provedor de dados: 18
Autores: Ippolito, J.A.; Levine, Jonah; Williams, Morgan.
One major issue related to climate change is the potential to improve soil water relations in light of changes in future precipitation patterns or reductions in water availability in drier portions of the world (such as the western US).  It appears that biochar may play a positive role, but that role may be soil texture related.  We performed a study with a sandy (Wolverine sand from Shelley, ID), silty (Portneuf silt loam from Kimberly, ID), and clay loam soil (Danville clay loam from a subsurface horizon, from near Oakland, CA) that received either 5 or 10% by volume of lodgepole biochar in either chipped (0.25-0.63”) or fine (0-0.25”) form; a control (no biochar) was also included.  Soil-biochar treatments were evenly mixed and placed into containers,...

Autores: Moore, Amber; Hines, Steve; Brown, B.; de Haro Marti, Mario; Falen, Christi; Chahine, Mireille; Fife, Tianna; Norell, Rick; Ippolito, J.A.
Corn silage is the predominant crop in Idaho used for   recovering phosphorus (P) that has accumulated in soils   from dairy manure applications. However, little is known   about how much P and other nutrients are being recov-  ered under Idaho conditions. The objective of the study   is to estimate P removal by irrigated corn silage crops   cultivated throughout southern Idaho with variable soil   test P concentrations, and to identify effects of increasing soil test P on tissue concentrations of P and on plant  P uptake.        Forty-two different corn silage fields in 2008 and   2009 were selected throughout southern Idaho for soil   and whole plant sampling at harvest. Soils were ana-  lyzed for Olsen P, plant tissue was measured for total P  content,...

Predicting soil-extractable Zn, P, Fe, and Cu in a biosolids-amended dryland wheat agroecosystem
Provedor de dados: 18
Autores: Barbarack, K.A.; Ippolito, J.A.
Biosolids Beneficial Use Programs frequently involve multiple applications at agronomic rates, with plant-nutrient availability changing as elements react with soil constituents over time. Consequently, can regression equations reasonably estimate plant availability of Zn, P, Fe, and Cu, where multiple applications of Littleton and Englewood, Colorado Wastewater Treatment Plant biosolids are applied to a dryland wheat (Triticum aestivum L.)-fallow agroecosystem? Before each growing season, we added Littleton and Englewood biosolids at rates of 0 to 11.2 dry Mg ha?1 to plots arranged in randomized complete blocks with four replications per treatment. Soil samples collected after each wheat harvest were analyzed using an NH4HCO3-diethylenetriaminepentaacetic...

Environmental Benefits of Biochar
Provedor de dados: 18
Autores: Ippolito, J.A.; Laird, D.A.; Busscher, W.J.
Understanding and improving environmental quality by reducing soil nutrient leaching losses, reducing bioavailability of environmental contaminants, sequestering C, reducing greenhouse gas emissions, and enhancing crop productivity in highly weathered or degraded soils, has been the goal of agroecosystem researchers and producers for years.  Biochar, produced by pyrolysis of biomass, may help attain these goals.  The desire to advance understanding of the environmental and agronomic implication of biochar utilization led to the organization of the 2010 ASA-CSSA-SSSA Environmental Quality Division session entitled Biochar Effects on the Environment and Agricultural Productivity (Long Beach, CA; Oct. 31-Nov. 3).  Twenty-five presentations from this session,...

Biochar is being evaluated by scientists from the United States Department of Agriculture (USDA) Agricultural Research Service (ARS) for its potential to sequester soil C, to improve soil health, and to increase crop yields.  ARS scientists from multiple locations such as Florence, SC, Kimberly, ID, Bowling Green, KY, Corvallis, OR, and St. Paul, MN, are conducting investigations with agronomic experiments at the laboratory, greenhouse, and field plot scales. To further expand biochars utility, ARS scientists have collaborated with United States Environmental Protection Agency (US EPA) investigators to reclaim mine-impacted soils. In the agronomic investigations, both positive and negative aspects of biochar application were revealed.  In some experiments,...

Macroscopic and microscopic variation in recovered magnesium phosphate materials: Implications for phosphorus removal processes and product re-use
Provedor de dados: 18
Autores: Massey, M.S.; Ippolito, J.A.; Davis, J.G.; Sheffield, R.E.
Phosphorus (P) recovery and re-use will become increasingly important for water quality protection and  sustainable nutrient cycling as environmental regulations become stricter and global P reserves decline.  The objective of this study was to examine and characterize several magnesium phosphates recovered  from actual wastewater under field conditions. Three types of particles were examined including crystalline  magnesium ammonium phosphate hexahydrate (struvite) recovered from dairy wastewater, crystalline  magnesium ammonium phosphate hydrate (dittmarite) recovered from a food processing facility,  and a heterogeneous product also recovered from dairy wastewater. The particles were analyzed using  ‘‘wet” chemical techniques, powder X-ray diffraction...

Zeolite Soil Application Method Affects Inorganic Nitrogen, Moisture, and Corn Growth
Provedor de dados: 18
Autores: Ippolito, J.A.; Tarkalson, D.D.; Lehrsch, G.A.
Adoption of new management techniques which improve soil water storage and soil nitrogen  plant availability yet limit nitrogen leaching may help improve environmental quality.  A benchtop study was conducted to determine the influence of a single urea fertilizer rate (224 kilograms of Nitrogen per hectare) applied with band or fully-mixed zeolite (Clinoptilolite) application rates (up to 90 megagrams per hectare) on ammonium-nitrogen and nitrate-nitrogen concentrations in a Portneuf silt loam.  Two additional greenhouse experiments were carried out to test the soil moisture status and corn growth in a Wolverine sand.  Mixing urea fertilizer into silt loam soil resulted in greater urea mineralization, but the mixed zeolite was more effective at adsorbing...

Fifteen Years of Wheat Yield, N Uptake, and Soil Nitrate-N Dynamics in a Biosolids-Amended Agroecosystem. Agriculture, Ecosystems and Environment
Provedor de dados: 18
Autores: Barbarick, K.A.; Ippolito, J.A.; McDaniel, J.P.
Understanding N dynamics in biosolids-amended agroecosystems can help avoid over-application and the potential for environmental degradation. We investigated 15-years of biosolids application to dryland-wheat, questioning what is the relationship between cumulative grain yield and N uptake (N removal) and biosolids or N fertilizer rates and how many times biosolids or N fertilizer are applied? How are wheat-grain production and N uptake intertwined with residual soil nitrate-N? We found that biosolids or N fertilizer rates plus the number of applications of each material produced planar-regression (3-dimensional) models with 15-years of grain yield and N uptake data (all R2 &gt; 0.93). To evaluate how yield or N uptake impacted residual soil nitrate-N, we...

Assessment of Phosphorus Retention in   Irrigation Laterals
Provedor de dados: 18
Autores: Ippolito, J.A.; Nelson, N.O.
Irrigation  laterals  transport  irrigation  return  flow,  including  water,  sediment, and dissolved nutrients, such as phosphorus (P), back to surface water bodies. Phosphorus transformations during transport can affect both P bioavailability and the best management practices selected to minimize P inputs to waters of the United States. The objective of this study  was  to  determine  P  retention  in  three  irrigation  laterals.  Soluble  reactive  P  (SRP) concentrations in lateral waters were increased from 0.08 to 0.25 mg L -1  (0.08 to 0.25 ppm) by constantly injecting a phosphate (PO4) solution for 2.5 hours. Bromide (Br) was used as a conservative tracer to determine dilution effects. Water was sampled at 10-minute intervals, beginning 30...

Riparian Shrub Metal Concentrations and Growth in Amended Fluvial Mine Tailings
Provedor de dados: 18
Autores: Meiman, P.; Davis, N.R.; Brummer, J.; Ippolito, J.A.
Fluvial mine tailing deposition has caused extensive riparian damage throughout the western United States.  Willows are often used for fluvial mine tailing revegetation, but some species accumulate excessive metal concentrations which could be detrimental to browsers.  In a greenhouse experiment, growth and metal accumulation of Geyer willow, Drummond’s willow, diamondleaf willow, Bebb willow, thinleaf alder, water birch, red-osier dogwood, and shrubby cinquefoil were evaluated for potential revegetation use.  Bare-root shrubs were grown in tailings collected from three acidic, metal-contaminated (i.e. cadmium, copper, lead, and zinc) fluvial deposits near Leadville, Colorado, USA.  Tailings were amended with only lime to raise the soil pH to 7, or with...

Biochar and Manure Affect Calcareous Soil and Corn Silage Nutrient Concentrations and Uptake.
Provedor de dados: 18
Autores: Lentz, R.D.; Ippolito, J.A.
When added to soils, carbon-rich biochar derived from the pyrolysis of woody materials can sequester atmospheric carbon dioxide, mitigate climate change, and potentially increase crop productivity.  However, research is needed to confirm the suitability and sustainability of biochar application to different soils.  We applied four treatments (dry wt.) to an irrigated calcareous soil in Nov. 2008: control; stockpiled dairy manure, 18.8 Mg/ha; hardwood-derived biochar, 22.4 Mg/ha; and manure + biochar using previous rates.  Nitrogen fertilizer was applied when needed (based on pre-season soil test N and crop requirements) in all plots and years with N mineralized from added manure included in this determination.  Available soil nutrients (NH4-N, NO3-N, Olsen...

Phosphorus losses from an irrigated watershed in the Northwestern U.S.: Case study of the Upper Snake Rock Watershed
Provedor de dados: 18
Autores: Bjorneberg, D.L.; Leytem, A.B.; Ippolito, J.A.; Koehn, A.C.
Watersheds utilizing surface water for irrigation often return a portion of the water to a water body. This irrigation return flow often includes sediment and nutrients that reduce the quality of the receiving water body. Research in the 82,000 ha Upper Snake Rock (USR) watershed from 2005 to 2008 showed that, on average, water diverted from the Snake River annually supplied 547 kg/ha of total suspended sediment (TSS), 1.1 kg/ha of total phosphorus (TP) and 0.50 kg/ha of dissolved phosphorus (DP) to the irrigation tract. Irrigation return flow from the USR watershed contributed 414 kg/ha of TSS, 0.71 kg/ha of TP and 0.32 kg/ha of DP back to the Snake River. Significantly more TP flowed into the watershed than returned to the Snake River while there was no...

Land coapplication of water treatment residuals (WTR) with biosolids has not been extensively researched, but the limited studies performed suggest that WTR sorb excess biosolids-borne P. To understand the long-term effects of a single coapplication and the short-term impacts of a repeated coapplication on soil P inorganic and organic transformations, 7.5- by 15-m plots with treatments of three different WTR rates with a single biosolids rate (5, 10, and 21 Mg WTR ha-1 and 10 Mg biosolids ha-1) surface coapplied once in 1991 or surface reapplied in 2002 were utilized. Soils from the 0- to 5-cm depth were collected in 2003 and 2004 and were sequentially fractionated for inorganic and organic P (Po). Inorganic P fractionation determined (i) soluble and...
