Split nitrogen applications for management of yield and protein of wheat grown in dryland
The feasibility of using split-N applications for managing yield and protein of wheat grown on dryland was studied in a field experiment initiated on a sandy loam and silt loam near Swift Current. Spring wheat was grown ...
Relationship between mineralizable N and hot KCl extractable NH4-N – variability at one site
To characterize the N supplying capacity of the soil at a site where a new long-term experiment was being initiated at Scott, Saskatchewan, we soil sampled the site in a systematic manner, taking 160 cores. We used these ...
Straw removal and fertilization on grain yields and soil organic matter in a fallow-wheat-wheat rotation
There is considerable interest being shown in the harvest and use of straw for industrial purposes in Manitoba and Alberta. In 1987 we measured soil C and N in a 30-year crop rotation experiment at Indian Head. Results at ...
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 ...
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 ...
