Nitrogen mineralization from organic residues: research opportunities.
Research on nitrogen (N) mineralization from organic residues is important to understand N cycling in soils. Here we review research on factors controlling net N mineralization as well as research onExpand

Base Temperature and Growing-Degree-Hour Requirements for the Emergence of Canola
Spring canola (Brassica napus L. and B. rapa L.) is sometimes planted when soil temperatures are below the optimum, causing farmers to have stand losses because of seed rotting in cold soil.Expand

Legume Green Fallow Effect on Soil Water Content at Wheat Planting and Wheat Yield
and yields were compared with wheat yields from conventional till other studies wheat yields following the green fallow wheat–fallow. Generally there were no significant differences in available soilExpand

Microbial communities and enzyme activities in soils under alternative crop rotations compared to wheat–fallow for the Central Great Plains
Winter wheat–fallow (W–F) rotation is the predominant cropping system in the Central Great Plains. However, other cropping systems are being suggested because reduced tillage and fallow can provideExpand

Forage Yield Response to Water Use for Dryland Corn, Millet, and Triticale in the Central Great Plains
Forages, with greater water use efficiency (WUE) than grain and seed crops, could be used to diversify reduced and no-till dryland cropping systems from the traditional wheat (Triticum aestivum L.)–Expand

Soil nitrogen mineralization influenced by crop rotation and nitrogen fertilization
An estimate of soil mineralizable N is needed to determine crop needs for N fertilizer. The objective of this research was to estimate soil net N mineralization in soils maintained in continuous cornExpand

Evaluating decision rules for dryland rotation crop selection
Abstract No-till dryland winter wheat ( Triticum aestivum L.)-fallow systems in the central Great Plains have more water available for crop production than the traditional conventionally tilledExpand

Quantifying effects of soil conditions on plant growth and crop production
Soil management decisions often are aimed at improving or maintaining the soil in a productive condition. Several indicators have been used to denote changes in the soil by various managementExpand

Change in Surface Soil Carbon under Rotated Corn in Eastern South Dakota
A diversified crop rotation may reduce fertilizer N inputs for corn (Zea mays L.) and increase soil organic C (SOC). Our objectives were to determine the effects of crop rotation and fertilizer N onExpand
