Provedor de dados: Depósito Institucional Abierto de Documentos Digitales del Colegio de Postgraduados (COLPOS DIGITAL )
Autores: Torres Guerrero, Carlos Alberto.
Los suelos de México han sido degradados en los últimos años en buena parte por la acción del hombre. Debido a las prácticas agronómicas empleadas en la mayor parte del país (labranza convencional, monocultivos y remoción de residuos vegetales de cosechas anteriores) los suelos con potencial agrícola se han visto disminuidos en su productividad. La Agricultura de Conservación (AC) ofrece un aprovechamiento sustentable del recurso suelo, asegurando su estabilidad y estructura, con el propósito de aumentar los rendimientos de los cultivos. El experimento que se reporta es de larga duración. Se inició en 1991 en el Batán Texcoco, Estado de México, en el Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT) y consta de 32 parcelas con diferentes...

Provedor de dados: Depósito Institucional Abierto de Documentos Digitales del Colegio de Postgraduados (COLPOS DIGITAL )
Autores: Chocobar Guerra, Eneyda Andrea.
Los organismos del suelo contribuyen en la formación y los cambios de la estructura física del suelo e influyen en la dinámica de los nutrientes por sus efectos sobre la inmovilización y humificación de la materia orgánica. Por lo anterior, es importante estudiar la edafofauna en sistemas de larga duración (15 años) porque repercute de manera directa en el rendimiento de los cultivos y en el mejoramiento del suelo. Estas cualidades además pueden ser empleadas para crear indicadores biológicos de calidad del suelo, con el objeto de potenciar manejos agrícolas con tendencias sustentables. La investigación se enfocó en clasificar (grupo taxonómico), cuantificar (Nº individuos m-2) medir biomasa (gramos m-2) y evaluar la variación poblacional de la edafofauna...

MODELING OF DRAFT AND ENERGY REQUIREMENTS OF A MOLDBOARD PLOW USING ARTIFICIAL NEURAL NETWORKS BASED ON TWO NOVEL VARIABLES
Provedor de dados: Engenharia Agrícola
Autores: Al-Janobi,Abdulrahman; Al-Hamed,Saad; Aboukarima,Abdulwahed; Almajhadi,Yousef.
ABSTRACT Draft and energy requirements are the most important factors in the activities of farm machinery management owing to their role in matching the tractor with implements for different tillage operations. This study's aim was to model the draft and energy requirements of a moldboard plow based on two novel variables. The first was the soil texture index (STI), which was formed from the clay, sand, and silt contents with a range of 0.03–0.84. The second variable was the field working index (FWI), formed by combining the plow width, plowing speed, soil bulk density, soil moisture content, plowing depth, and tractor power into one dimensionless variable, which had a range of 7.17–82.45. The coefficient of determination (R2) values obtained using a...

K-NEAREST NEIGHBORS METHOD FOR PREDICTION OF FUEL CONSUMPTION IN TRACTOR-CHISEL PLOW SYSTEMS
Provedor de dados: Engenharia Agrícola
Autores: Al-Dosary,Naji Mordi Naji; Al-Hamed,Saad Abdulrahman; Aboukarima,Abdulwahed Mohamed.
ABSTRACT Most important farm operations require a significant amount of energy, and this consumes a major portion of the farm's budget. Consequently, analyzing the fuel consumption of agricultural machinery for farm operations of different sizes makes it possible to predict fuel consumption to set an appropriate budget for energy. The main purpose of this study was to determine the ability of the k-nearest neighbors (KNN) algorithm to predict the fuel consumption of tractor–chisel plow systems correctly. A training-set design of 139 points of 173 data points obtained from the literature was utilized, and the remaining 34 data points were applied as a test set. The input parameters were tractor power, plowing width, depth and speed of plowing, soil...

Positioning of fertilizer in corn sowing
Provedor de dados: Engenharia Agrícola
Autores: Weirich Neto,Pedro H.; Justino,Altair; Frare,Ivo; Gomes,Jorge N.; Garcia,Luiz C.
The aim of this study was to determine whether the form of placing the fertilizer by the planter during the sowing under mulch in the no till system affects the yield of corn. The treatments consisted of placing the fertilizer during the seeding 0.05 m below and beside the seed, in front of the cutting blade and without fertilizer, in 03 farms during 03 cropping years. The experimental design at each farm was the randomized block, with 08 repetitions, whose plots had 30 m² each. The initial population and yield components were evaluated. Under the experimental conditions it is concluded that base fertilization can affect the yield. Fertilizer placement can affect the initial stand, but not the yield.

Evaluation of Nitrogen and Phosphorus Fertilizer Placement With Strip Tillage for Irrigated Pacific Northwest Corn Production
Provedor de dados: NWISRL Publications
Autores: Tarkalson, D.D.; Bjorneberg, D.L.
Nutrient placement options with strip tillage (ST) can potentially improve plant nutrient utilization and increase crop yield compared to conventional fertilizer placement practices under conventional tillage (CT). The effects of tillage practice and nitrogen (N) and phosphorus (P) placement on grain yield, biomass yield (whole plant, grain + cobs + stover), and N and P uptake of field corn (Zea mays L.) were assessed on four sites during 2007 and 2009 at the USDA-ARS Northwest Irrigation &amp; Soils Research Laboratory at Kimberly, ID. During each year, two locations (eroded and not eroded from furrow irrigation) were utilized as study locations. Band placement of fertilizer with ST increased corn grain yield by 12.5 % (11 bu/acre) and 25.9% (26 bu/acre)...

Beef feedlot manure distributed to row crop production areas is a potential surface water contaminant source of the steroid hormones commonly used in beef cattle production. This article reports on research conducted at the University of Nebraska Haskell Agricultural Laboratory near Concord, Nebraska, in July 2009. Manure, collected from beef feedlot pens, was stockpiled for ten months prior to application to a row crop field. Previous research identified that the detection frequency of steroid hormones in beef manure varies greatly. Thus, a surrogate (17 alpha-ethynylestradiol, EE2) was applied at a rate of 75 g per ha to ensure detectable concentrations in surface runoff samples. EE2 was applied directly to beef cattle manure and to bare soil. The EE2...

Influence of sugarbeet tillage systems on rhizoctonia-bacterial root rot complex
Provedor de dados: NWISRL Publications
Autores: Strausbaugh, C.A.; Eujayl, Imad A.
The Rhizoctonia-bacterial root rot complex on sugarbeet caused by Rhizoctonia solani and Leuconostoc mesenteroides can cause significant yield losses.  To investigate the impact of different tillage systems on this complex, field studies were conducted from 2009 to 2011.  Split blocks with conventional and strip tillage as main plot treatments were arranged in a randomized complete block design with four replications.  Within main plots, there were seven treatments (non-inoculated check and six R. solani AG 2-2 IIIB strains).  Regardless of tillage, the roots responded in a similar manner for fungal rot (conventional 8% versus strip 7%), bacterial rot (26% versus 34%), total rot (33% versus 41%), neighboring roots infected (1.7 roots versus 1.5 roots),...

Nitrogen and Phosphorus Fertilizer Placement in Corn Production
Provedor de dados: NWISRL Publications
Autores: Tarkalson, D.D.; Bjorneberg, D.L.
The use of strip tillage and other conservation tillage practices are used to conserve soil and soil water through residue management and reduce tillage costs in many areas of the Corn Belt. However, in the Pacific Northwest these tillage practices are less common. Strip tillage is becoming more common in the sugar beet industry in southern Idaho and due to the high dairy cow populations, corn production is increasing. The dual use of strip tillage for sugar beet and corn production will likely continue to develop, increasing the need for strip tillage best management practices in this region. In this study we evaluated the effects of common and logical nitrogen and phosphorus placements with strip tillage and conventional tillage on grain yield on four...

Autores: Garcia, J.P.; Wortmann, C.S.; Mamo, M.; Drijber, R.; Tarkalson, D.
Stratification of nutrient availability, especially of P, that develops  with continuous no-till (NT) can affect runoff nutrient concentration  and possibly nutrient uptake. The effects of composted manure application  and one-time tillage of NT on the distribution of soil chemical  properties, root colonization by arbuscular mycorrhizae (AM), and  plant P uptake were determined. Research was conducted on Typic  Argiudoll and Moffic Hapludaff soils under rainfed corn (Zea mays L.)  or sorghum [Sorghum bicolor (L.) Moench.] rotated with soybean  [Glycine max (L.) Men.] in eastern Nebraska. Tillage treatments included  NT, disk, chisel, moldboard plow (MP), and mini-moldboard  plow (MMP). Subplots had either 0 or 87.4 kg P ha -I- applied in compost  before...

Provedor de dados: NWISRL Publications
Autores: Moore, Amber; Tarkalson, D.D.
Decomposition rates directly affect carbon and nitrogen ratios, which can affect nitrogen mineralization rates. The objective of this research is to determine the effect of tillage method and nitrogen rate on nitrogen available to sugar beets planted after a cereal crop. This two-year field study conducted in Kimberly, Idaho, consisted of three tillage methods (moldboard plow, chisel plow, and strip tillage), two tillage timings (fall and spring), and four fertilizer N rates plus a control. Soils from each plot were sampled shortly after nitrogen fertilization and incubated at average seasonal temperatures for Kimberly, Idaho to monitor nitrogen mineralization patterns. In 2008, we found that at N fertilizer rates of 0, 50, and 100 lbs N per acre,...

Comparison of fall and spring bedding for furrow irrigated potatoes following fall moldboard or chisel plowing
Provedor de dados: NWISRL Publications
Autores: Shock, C.; Stieber, T.; Eldredge, E.; Sojka, R.; Kennedy-Ketcheson, E.
The decision to fall or spring bed potatoes is often dictated by weather and  processor contract agreements. Although there are advantages to both fall an(  spring bedding, soil conditions are often wet in the spring in Malheur County,  Oregon. Spring bedding of wet soils leads to soil compaction and decreased  water infiltration. The primary objective of the study was to determine the  effects of fall or spring bedding on tuber yields and quality under furrow  irrigation.  Determining the most effective method of fall potato ground preparation was  the second objective of the trial. Land for potato production is normally  moldboard plowed in the fall. Chisel plowing may provide better placement of  residues in bedded ground and thus promote higher...

Effects of Alfalfa, Crop Sequence, and Tillage Practice on Intake Rates of Pullman Silty Clay Loam and Grain Yields
Provedor de dados: NWISRL Publications
Autores: Jensen, M.E.; Sletten, W.H.
The High Plains of Texas is one of the largest irrigated areas in the  United States. Most of the 5.7 million acres irrigated in Texas  (1959 census) is concentrated in the High Plains. The area is unique  because most of the irrigated land is of one soil series-Pullman.  Pullman soils represent over 5 million acres of the “hardlands” in the  Southern High Plains of Texas, New Mexico, and Oklahoma.  The term “hardlands” is used extensively when referring to the  High Plains because of the soil characteristics of the area. The soils  are mostly clay loams and silty clay loams. The have low intake  rates, are dense, and become very hard and difficult to till when dry.  The differences between the clay loams and silty clay loams are  minor. The physical...

Effects of tillage system and nitrogen supply on sugarbeet production
Provedor de dados: NWISRL Publications
Autores: Tarkalson, D.D.; Bjorneberg, D.L.; Moore, Amber.
The sugarbeet (Beta vulgaris L.) industry in Idaho is interested in strip tillage (ST) primarily due to the potential savings in tillage costs. This study was conducted to evaluate the use of strip tillage in Idaho compared to conventional tillage practices and to evaluate N requirements of sugarbeet under ST and conventional tillage.  The effect of tillage method (strip tillage, moldboard plow system [MP], and chisel plow system [CP]) and N supply (5 levels) on sugarbeet production factors were investigated in Kimberly, ID from 2008 to 2010 on a Portneuf silt loam with barley as the previous crop. Root and estimated recoverable sucrose (ERS) yields were the same under all three tillage practices.  However, estimated tillage costs for ST were from 53...

Weeds Biomass as Affected by Tillage Practices and Cropping Systems under a Semiarid Environment
Provedor de dados: Planta Daninha
Autores: MEHMOOD-UL-HASSAN,; QAYYUM,A.; SHER,A.; TAHIR,M.I.; AZEEM,M.; FAREED,A.
ABSTRACT: Tillage practice has a significant role on weeds eradication and soil water conservation in crop production. Under semiarid agriculture, the monsoon rains (65%) are major source of water in Potohar, Pakistan, which can effectively be used mostly for winter crops production. To evaluate the impact of different tillage system for prevailing cropping systems and their weeds biomass under semiarid conditions, field experiment was conducted at the Arid University Research Farm Koont Rawalpindi (Pakistan) during crop growth seasons 2013-14 and 2014-15. Tillage systems as treatments were (a) three cultivations with a cultivator, as control treatment, (b) mold-board with two cultivations, (c) chisel-plough with two cultivations and (d) minimum tillage...

Autores: MAQSOOD,Q.; ABBAS,R.N.; KHALIQ,A.; ZAHIR,Z.A.
ABSTRACT: A field trial was conducted with the aim of assessing weed seed bank status of soil under maize cultivation. It was worked out by sampling from soil corer at different depths ranging from 0-5, 5-10, 10-15, 15-20 and 20-25 cm. Weed seed bank was monitored with a cultivator, a rotavator, a mouldboard plough (MB) and a chisel plough in tilled plots under Atrazine 330 EC at 1.00 kg a.i. ha-1 at 20 DAS, hand weeding at 20 and 40 DAS and no weeding. Sixteen weed species were identified in soil samples, four species contributing about 72% of the total weed seed bank. Tillage system was more important determinant of weed seed density than the weed management practices. Movement pattern of weed seeds by all tillage treatments differ significantly over...

This study examines the impact of stochastic harvest field time, corn cob and stover harvest technologies, increases in farm size, and alternative tillage practices on profit maximizing potential of corn cob and stover collection in North Dakota. Using three mathematical programming models, we analyze farmers’ harvest activities under 1) corn grain only harvest option, 2) simultaneous corn grain and cob harvest(one-pass)  option 3) separate corn grain and stover harvest (two-pass) option. Under the first corn grain only option, farmers are able to complete harvesting corn grain and achieve maximum net income in a fairly short amount of time with existing combine technology. However, under the simultaneous corn grain and cob one-pass harvest option, our...

Autores: Fernandez-Cornejo,   Jorge; McBride,   William D.
Use of crop biotechnology products, such as genetically engineered (GE) crops with input traits for pest management, has risen dramatically since commercial approval in the mid-1990s. This report addresses several of the economic dimensions regarding farmer adoption of bioengineered crops, including herbicidetolerant and insect-resistant varieties. In particular, the report examines: (1) the extent of adoption of bioengineered crops, their diffusion path, and expected adoption rates over the next few years; (2) factors affecting the adoption of bioengineered crops; and (3) farm-level impacts of the adoption of bioengineered crops. Data used in the analysis are mostly from USDA surveys.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Horowitz,   John K.; Ebel,   Robert M.; Ueda,   Kohei.
Most U.S. farmers prepare their soil for seeding and weed and pest control through tillage—plowing operations that disturb the soil. Tillage practices affect soil carbon, water pollution, and farmers’ energy and pesticide use, and therefore data on tillage can be valuable for understanding the practice’s role in reaching climate and other environmental goals. In order to help policymakers and other interested parties better understand U.S. tillage practices and, especially, those practices’ potential contribution to climate-change efforts, ERS researchers compiled data from the Agricultural Resource Management Survey and the National Resources Inventory-Conservation Effects Assessment Project’s Cropland Survey. The data show that approximately 35.5 percent...

An Economic Evaluation of Conservation Farming Practices for the Central West of NSW
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Farrell,   Terence C.
Economic benefits that arise from conservation farming practices need to be assessed over several years to account for improvements in soil structure and nutrient levels. A gross margin model was used to assess benefits over the eight-year period 1999-2006 for 12 regions in the central west of NSW. The annual benefits from improved soil structure ranged from $2.46 to $12.82 per hectare (ha). A reduction in tractor power produced annual savings in the range of $0.60 to $4.05 per ha. The cost of soil compaction by livestock grazing on crop areas ranged from $3.41 to $14.90 per ha. The break-even time to pay back costs for the conversion of machinery for no-till seeding was two to three seasons.

An interview based survey of farm landowners in the south east corner of Saskatchewan was undertaken to evaluate the provision of wildlife habitat by agriculture. Producers were asked to provide management information regarding a piece of their land that was managed as a unit. Within the past ten years there has been a reduction in the conversion of remaining native land to crop land, an increase in conversion of annual crop land to perennial cover crops, an increase in the use of minimum disturbance (no-till) farming, and a decrease in the use of fire on stubble fields and sloughs. Many producers in the area often stated economic reasons for their current land use division. Even ecological reasons (productive capacity of the soil, poor cropping soil,...

RISK EFFECTS OF ALTERNATIVE WINTER COVER CROP, TILLAGE, AND NITROGEN FERTILIZATION SYSTEMS IN COTTON PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Larson,   James A.; Jaenicke,   Edward C.; Roberts,   Roland K.; Tyler,   Donald D.
A Just-Pope model was developed to assess tillage, nitrogen, weather, and pest effects on risk for cotton grown after alternative winter cover crops.  Yield risk for cotton after hairy vetch was less than for cotton with no winter cover when no nitrogen fertilizer was used to supplement the vetch nitrogen.  However, because cotton after vetch has a higher production cost, farmers growing conventionally tilled cotton may be slow to adapt because risk-return tradeoffs may be unacceptable under risk neutrality and risk aversion.  For risk-averse farmers who have already adopted no tillage, cotton grown after hairy vetch is risk efficient.

Although many irrigation systems in the dry zone of Sri Lanka have water shortage problems, water consumption is very high during land preparation. This paper analyzes the impact of institutional interventions on efficient water management, especially during the land preparation period. It provides a comprehensive understanding of the factors behind prolonged periods of land preparation so that system managers and farmers communities can develop appropriate interventions to reduce water consumption.

Many forested areas have been converted to intensive agricultural use to satisfy food, fiber, and forage production for a growing world population. There is great interest in evaluating forest conversion to cultivated land because this conversion adversely affects several soil properties. We examined soil microbial, physical, and chemical properties in an Oxisol (Latossolo Vermelho distrófico) of southern Brazil 24 years after forest conversion to a perennial crop with coffee or annual grain crops (maize and soybeans) in conventional tillage or no-tillage. One goal was to determine which soil quality parameters seemed most sensitive to change. A second goal was to test the hypothesis that no-tillage optimized preservation of soil quality indicators in...

Soil water retention and s index after crop rotation and chiseling
Provedor de dados: Revista Brasileira de Ciência do Solo
Autores: Calonego,Juliano Carlos; Rosolem,Ciro Antonio.
Soil compaction can be minimized either mechanically or biologically, using plant species with vigorous root systems. An experiment was carried out with soybean (Glycine max) in rotation with triticale (X Triticosecale) and sunflower (Helianthus annuus) in fall-winter associated with pearl millet (Pennisetum glaucum), grain sorghum (Sorghum bicolor) or sunn hemp (Crotalaria juncea) in spring. Crop rotation under no-till was compared with mechanical chiseling. The experiment was carried out in Botucatu, São Paulo State, Brazil. Soil quality was estimated using the S index and soil water retention curves (in the layers of 0-0.05, 0.075-0.125, 0.15-0.20, 0.275-0.325, and 0.475-0.525 m deep).

Fractal dimension and geostatistical parameters for soil microrelief as a function of cumulative precipitation
Provedor de dados: Scientia Agricola
Autores: Vázquez,Eva Vidal; Vieira,Sidney Rosa; De Maria,Isabella Clerici; González,Antonio Paz.
Surface roughness isinfluenced by type and intensity of soil tillage among other factors, and it changes considerably with rain. In microrelief studies the advantages of using indices such as the fractal dimension, D, and the crossover length, l, is that they allow the partition of the roughness characteristics into properties that depend purely on the scale and on a scale free component, respectively. On the other hand, some geostatistical parameters may provide different ways to understand soil surface variability not addressed with fractal parameters. Changes in fractal dimension and semivariogram parameters for surface roughness evolution were evaluated as a function of cumulative rainfall on Oxisol samples over six tillage treatments, namely, disc...

Provedor de dados: Agrociencia
Autores: Sohail-Ijaz,Shahzada; Ali,Safdar.
Clean fallowing has been criticized in the recent past due to the fact that it causes accelerated soil erosion, emission of CO2 to the atmosphere and reduction in farm income. In an effort to reduce fallowing in Pothwar, Pakistan, field experiments were carried out from 2005 through 2008 at three locations (Rawalpindi, Chakwal and Fateh Jang). The experimental design was split-plot and treatments were applied as follows: conventional cultivator, moldboard plow and minimum tillage in main plots; fallow, legume (mungbean, Vigna radiata) and mulch of wheat straw were used in sub plots. Wheat (Triticum aestivum) was planted in all the subplots during winter. All the treatment plots had equivalent volumetric water content at wheat planting. Consequently, the...
