Soybean nitrogen dynamics: Nitrogen fixation, yield, and residue decomposition
… to environmental factors, and plant tissue decomposition to understand better N cycling and improve Midwestern US N budget estimations.</p> <p>A long-term incubation study was conducted by using aboveground plant litter of soybean along with three other plants (maize, oats, and alfalfa), to …

Corn planting strategies in the United States Corn Belt
… corn production due to large amounts of corn residue, which may interfere with planting operations and contributes to keeping soils cooler and wetter, delaying field operations. A practice in Illinois is to apply post-harvest nitrogen (N) fertilizer to accelerate residue decomposition. A 2-yr …

A Measurement of Conservation Agriculture’s Effect on Nitrogen and Carbon Mineralization Rates for Agricultural Recommendations in Haiti’s Central Plateau
… field experiment in the summer of 2013 assessed decomposition rates and nutrient mineralization from common cash crops and two potential cover crops either on the soil surface or buried at 15 cm. The relative difficulty and expense of conducting these types of field trials led to the development …

THE INFLUENCE OF PULSE CROPS ON SOIL PHOSPHORUS AVAILABILITY TO SUBSEQUENT WHEAT CROPS IN THE BROWN SOIL ZONE OF SASKATCHEWAN
… in the Brown soil zone of Saskatchewan. Pulse residues generally had higher P concentrations than wheat residue when grown under similar soil fertility and environmental conditions. Higher P contents corresponded to lower carbon (C)to P ratios (C:P),which lowered the potential for P …

Managing the continuous corn yield penalty with crop and residue management
… to the CCYP are soil nitrogen availability, residue accumulation, and the weather. Therefore, the objective of this research was to evaluate and determine management practices that could help relieve the yield penalty associated with production of continuous corn compared to when rotated with …

Decomposition of Crop Residues
Crop residues are the prime source of energy and nutrients affecting soil biological, chemical and physical processes, including organic matter formation. This study examined the effects of management on the rate of decomposition of crop residues in the laboratory and field. It also measured the …

Decomposition and Nitrogen Release From Leucaena leucocephala,senna siamea, and Flemingia macrophylla Litter in managed alleys for maize in Zambia:Infuence of inorganic-N and litter Quality
… quality and inorganic nitrogen (N) on rate of decomposition and N release pattern by three leguminous woody species were investigated under field conditions by the litterbag technique. The species studied in 1994/1995 were Leucaena leucocephala, Senna siamea and Flemingia macrophylla. This …

MEASURING AND MODELLING COVER CROP GROWTH AND AGRONOMIC EFFECTS
… on the crop-soil system, including cover crop residue degradation on soil surface, is lacking. This work aimed at representing, within the ARMOSA cropping system model framework, frost sensitive cover crop species growth, development, and agronomic effects by enriching the simulation model with …

Effect of legume residues on P availability in soil and P uptake by the following wheat.
… added to soil as inorganic fertiliser or as crop residues. It has been shown that addition of legume residues can increase P availability by supplying P within the residues but also by mobilising native soil P which could reduce the dependence on inorganic P fertilization for crop growth. In soil, …
