Where is nitrogen going in long-term cropping systems?
Fertilizer nitrogen use efficiency (NUE) is normally low, and has led to the idea that a large proportion of N applied as fertilizer is lost from the soil. However, N balances calculated for a long-term rotation study at ...
Relationship between soil texture and soil organic carbon at small field scale
The capacity of a soil to store organic carbon is related to its particle size distribution, or soil texture, mainly because the capacity of clay particles to stabilize organic materials. A study of the relationship of ...
Managing an annual legume green manure crop for fallow replacement in southwestern Saskatchewan
Some scientists have suggested that in the Brown soil zone an annual legume green manure crop (GM) could be used as a partial-fallow replacement to protect the soil against erosion and increase its N fertility, particularly ...
Effect of crop rotations on potentially mineralizable-N and amino compounds in a Black Chernozem at Indian Head
The effect (i) of fertilization on fallow-wheat (F-W), F-W-W, and continuous wheat; (ii) of baling straw on F-W-W (fertilized); (iii) of including sweetclover as green manure (GM) in F-W-W (unfertilized); and (iv) of ...
Nitrogen fertilizer management for maximum economic yields of spring wheat in southwestern Saskatchewan
The effects of snow trapping by means of alternative cereal stubble heights, and of N fertilizer management in terms of rates, times of application, and methods of placement on soil moisture conservation, grain yields, and ...
Spring wheat response to nitrogen and water
Economic and risk considerations of nitrogen fertilizer use in the Brown Soil Zone
Optimum use of nitrogen fertilizer requires consideration of factors that influence plant response and those that govern the decisions of producers. The response of spring wheat to soil moisture and N fertilizer was assessed ...
