Biochar and Manure Affect Calcareous Soil and Corn Silage Nutrient Concentrations and Uptake. NWISRL
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...

Changes in soil test phosphorus and phosphorus in runoff from calcareous soils receiving manure, compost, and fertilizer application with and without alum NWISRL
Leytem, A.B.; Bjorneberg, D.L..
Intensification of the dairy industry in southern Idaho had led to the over-application of manures and a buildup of soil phosphorus (P) which is a potential threat to water quality in the region. As the use of alum has been shown to reduce both soluble manure P and runoff P from alum treated manures, the objective of this study was to determine if surface applications of alum to dairy manure and compost prior to soil incorporation would reduce P losses under furrow irrigation on a calcareous soil. The effects of manure, compost, and fertilizer application with and without alum treatment on soil P, runoff P and aluminum (Al) under furrow irrigation, crop yield, tissue P concentrations and P removal over a four year period were investigated in Kimberly, ID,...

Crecimiento vegetativo, productividad y tolerancia a la deficiencia de hierro en seis portainjertos de duraznero creciendo en suelo calcáreo Ciencia e Investigación Agraria
Sotomayor,Carlos; Ruiz,Rafael; Castro,Jorge.
Iron deficiency is a major problem that affects many fruit crops grown on calcareous soils. A four-year study was conducted to evaluate the effect of calcareous soils on the vegetative growth and productivity of six peach rootstocks (Nemaguard, Atlas, MRS 2/5, Cadaman, GF 677 and GxN15) grafted with 'Ruby Diamond' nectarines. Trees were planted in 100 L containers filled with a sandy loam textured, calcareous soil (6.3% active calcium carbonate) with a pH of 8.0 and an intermediate level of available iron (5 mg kg-1 of Fe+2). The trunk diameter during the 4th growing season was larger in GF 677, GN 15, Cadaman and Atlas, whereas Nemaguard and MRS 2/5 showed smaller average values. Cadaman and Atlas presented the highest pruning weight (a measure of...

Delinearing site-specific management zones for pH-induced iron chlorosis NWISRL
Kyaw, T.; Ferguson, R.B.; Adamchuk, V.I.; Marx, D.B.; Tarkalson, D.D.; McCallister, D.L..
Iron chlorosis can limit crop yield, especially on calcareous soil. Typical management for iron chlorosis includes the use of iron fertilizers or chlorosis tolerant cultivars. Calcareous and non-calcareous soil can be interspersed within fields. If chlorosis-prone areas within fields can be predicted accurately, site-specific use of iron fertilizers and chlorosis-tolerant cultivars might be more profitable than uniform management. In this study, the use of vegetation indices (VI) derived from aerial imagery, on-the-go measurement of soil pH and apparent soil electrical conductivity (ECa) were evaluated for their potential to delineate chlorosis management zones. The study was conducted at six sites in 2004 and 2005. There was a significant statistical...

Designer, acidic biochar influences calcareous soil characteristics NWISRL
Ippolito, J.A.; Ducey, Tom; Cantrell, K.B.; Novak, J.M.; Lentz, R.D..
An acidic (pH 5.8) biochar was created using a low pyrolysis temperature (350 degrees celsius) and steam activation to potentially improve the soil physicochemical status of an eroded calcareous soil. Biochar was added at 0, 1, 2, and 10 percent (by weight) to an eroded Portneuf soil (coarse-silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid) and destructively sampled at 1, 2, 3, 4, 5, and 6 month intervals. Soil was analyzed for volumetric water content, pH, nitrate-nitrogen, ammonium-nitrogen, plant-available iron, zinc, manganese, copper, and phosphorus, organic carbon, carbon dioxide respiration, and microbial enumeration via extractable DNA and 16S rRNA gene copies. Soil water content increased with biochar application regardless of rate;...

Hardwood biochar influences calcareous soil physicochemical and microbiological status NWISRL
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...

Linking manure properties to phosphorus solubility in calcareous soils: Importance of the manure carbon to phosphorus ratio NWISRL
Leytem, A.B.; Turner, B.L.; Raboy, V.; Peterson, K.L..
Land application of manure can increase P transfer in runoff, although the risk depends in part on the characteristics of the manure. We assessed this for calcareous soils using manures from swine (Sus domesticus) fed one of five barley varieties (Hordeum vulgare L.), including four low phytate mutants and a normal variety, to produce manures with a range of total P (6.8-4.9 g P water-soluble P (4.3-8.0 g P kg-'), total N/P ratios (2.5:1-5.5:1), and total C/P ratios (31:1-67:1). Two experiments were conducted. First, manures were incorporated into three soils on a N (150 mg N kg-' soil) or P (27.5 mg P kg-1 soil) basis three times during a 7-wk incubation. Second, 10 additional soils were incubated for 2 wk following a single P-based manure...

Phosphorus Fertility Relationships of Central Washington Irrigated Soils (with special emphasis on exposed calcareous subsoils) NWISRL
James, D.W.; Leggett, G.E.; Dow, A.I..
To facilitate irrigation in central Washington, land is leveled or smoothed on a broad scale. As a result, the calcareous and extremely infertile subsoils are exposed and used directly as a medium for plant growth. Phosphorus fertilizer requirements of exposed subsoils were determined by measuring crop yield and P uptake on plots that were fertilized in the current and one, two or three preceding seasons. Annual crops used as indicators of P availability at three sites were field beans, Sudangrass and sugar beets. A supplementary experiment involved fertilization of a previously established alfalfa crop. Crop growth and P uptake results were correlated with sodium bicarbonate soil testing
