- Abstract:
- ... Risk is an intrinsic part of cropping systems and cropping system management. A stochastic budgeting example using field plot data is used to illustrate common sources of risk and methods producers use to deal with risk. An additional example utilizes crop simulation modeling to illustrate the potential importance of timeliness risk in cropping system choices. The examples provide a framework for ...

- Abstract:
- ... The southeast, despite its abundant rainfall, suffers short-term summer droughts with detrimental effect on crop yield. No-till production systems provide added insurance against such conditions by improving infiltration, and conserving moisture in drought-prone soils. In three years of experiment near Watkinsville, GA, no-till cotton treatments maintained higher soil moisture content, more vegeta ...

- Abstract:
- ... Cotton [Gossipium hirsutum (L.)] is a dominant crop in the Southeast. It is largely grown using conventional tillage and fertilizers. Georgia and bordering states produce about 42% of the poultry in the United States, but only a small percentage of the litter is utilized as fertilizer. We measured and compared cotton yield from conventional tillage (CT) and no-till (NT) plots fertilized either wit ...

The effects of a “double-cut plow” method of mulch tillage on fertility, as measured by soil nitrate-N, soluble nutrients in leaf, grain yields, and nutrient content of the corn plant, and on physical properties of the soil were investigated at Blacksburg, Va. The standard 3-year rotation of corn, small grain, and clover-grass with mulch tillage practice during the corn year was compared with a si ...

Corn was grown each summer following winter cover crops of vetch and rye mixed and crimson clover. Mulch tilled land was prepared for planting corn by disk-harrowing, and by disk-harrowing plus loosening the soil with a spring-tooth tiller. A disk or moldboard ...

- Abstract:
- ... SypnosisNitrogen losses from cultivated soils were most rapid immediately after breaking the native sod. Losses gradually decreased with continued cultivation in experiments from 1916 to 1946. Row crop production caused the largest losses of nitrogen. Small grain production caused the smallest losses. Under small grains, nitrogen losses had ceased by 1938. Elsewhere losses continued through 1946. ...

Low yield levels and low rainfall combined with high degrees of land slope tended to increase this difference. Weed control practices, conventional seedbed preparation, soil surface texture and internal drainage, and previous crop had no effect on the yield difference between t ...

- Abstract:

These results were obtained under high-intensity, simulated rainfall with rows and tillage parallel to the slope. Infiltration averaged 24% greater and soil loss averaged 34% less from minimum tillage treatments than from conventional treatments. The ...

- Abstract:
- ... Management practices are needed that will permit economic crop production in hilly terrain without excessive soil and water losses. Field studies were conducted over a 3-year period to determine the effects of two rates of atrazine on yield of corn (Zea mays L.) sod planted in orchardgrass (Dactylis glomerata L.) for 2 years and to determine the residual effect of atrazine on germination and growt ...

- Abstract:
- ... This study was prompted by the huge feed grain deficits which increase annually in the Southeast. The need exists to find ways of increasing grain production efficiently. Cropping-tillage systems designed to accomplish this were studied. Soybeans [Glycine max (L.) Merr.] and grain sorghum [Sorghum bicolor (L.) Moench.] were double cropped following wheat (Triticum aestivum L.) on a Blackbelt soil. ...

- Abstract:
- ... In the mid-1960‘s farmers were considering no-plow tillage as a way to cut production costs and achieve more timely planting, and environmentalists were promoting conservation tillage as a primary means of cutting erosion losses. There was an obvious need for a more detailed evaluation of where no-plow tillage methods were adapted in the Corn Belt. The objective of this research was to determine c ...

Nitrate under both cultural treatments was sampled before and after June rainfall periods in both years. A large fraction of the nitrate was l ...

Five tillage-planting systems were compared: coulter-plant, till-plant, chisel-plant, disk and coulter-plant, and conventional-plant. The coulter and chisel systems controlled soil loss, but runoff water c ...

Recent adoption of no-tillage planting systems by many farmers has raised questions concerning comparative yields with conventional tillage systems and problems associated with nutrient absorption. No-tillage systems gem erally require surface application of P and K, thus studies are needed to determine whether surface-applied nutrients can supply plant needs. The objectives of this study were to ...

- Abstract:
- ... Many coarse-textured surface soils in the southeastern Coastal Plain are prone to develop tillage pans which restrict root proliferation and moisture utilization in subsoils. The effect of tillage treatments on soybean [Glycine max (L.) Merr.] growth and soil moisture utilization was investigated on Norfolk sandy loam (Typic Paleudult) and Wagram loamy sand (Arenic Paleudult) soils. The three till ...

- Abstract:
- ... In wheat [Triticum aestivum (L.) Thell] producing regions with adequate frost-free days to permit doublecropping, water is often the most limiting factor in producing the second crop. To more fully utilize climatic resources and land after the harvest of wheat grain, a field study was conducted on a Wynona silty clay loam (Cumulic Haplaquolls) to analyze the effects of tillage and row spacings on ...

- Abstract:
- ... Corn (Zea mays L.) yields less with no-till or reduced tillage than with conventional tillage on medium and fine-textured soils in Ontario, Canada. This study was undertaken to determine whether rates of N, P, or K above those normally recommended could increase the notill yields. Annual rates of 120 and 240 kg N/ha, and initial rates of 95, 475, and 1,260 kg P/ha and 95, 665, and 1,330 kg K/ha we ...

These are residual herbicides and the effects of residues has been long recognized to be influenced by tillage. Careful evaluation of these compounds was thus needed before growers could consider growing sweet corn (Zea mays L.) following peas in a double cropping system. Peas were therefore established in ...

Among the methods tried were replacement of natural fallow with leguminous covercrops, planted grass fallow, and late minimum or zero tillage. With zero tillage, weed control and fertilizer application methods are problems that need immediate attention. An experiment conducted for 4 years employed the foll ...

Because A. flavus and A. parasiticus are indigenous soil inhabitants, the soil is an impor ...

Corn (Zea mays L.) was fertilized with 84 or 168 kg N ha⁻¹ as ¹⁵N-depleted NH₄NO₃. Nitrogen was surface applied as a solution on a Maury silt loam soil (fine , mixed, mesic Typic Paleudalfs). There was no mechanical disturbance of the soil in the no-tillage treatment (NT); conv ...

- Abstract:
- ... The gaseous losses of N from conventional-till (CT) and zero-till (ZT) crop fields were 3 to 7 and 12 to 16 kg N ha⁻¹ y⁻¹, respectively. In contrast, losses from CT and ZT fallow were severalfold higher, namely, 12 to 14 and 34 kg N ha⁻¹, respectively. The more dense surface soil and consistently higher moisture content (lower air-filled porosity) were identified as major factors affecting increas ...

Conservation tillage systems, such as no-tillage, have shown tremendous potential for controlling erosion, yet results in crop growth and yield have varied with location, environment, and soil type. The objectives of this study were to evaluate the effects of no-tillage (NT) and conventional tillage (CT) on growth and development of grain sorghum (Sorghum bicolor L. Moench) grown on a heavy clay s ...
