Nitrogen effects on water use efficiency in the semi-arid Canadian prairies
In the semiarid environment of the Canadian prairies, water is the main constraint to crop production. Few studies have examined the influence of fertilizer on water use efficiency (WUE) and fewer still have made comparisons ...
Effectiveness of meat and bone meal and distillers grain ash as a phosphorus source for crops
Production of biogas from organic materials via gasification also generates a valuable byproduct of ash. Ash contains the original nutrient present in organic materials, except carbon, nitrogen and sulfur that are lost as ...
Canola: are safe rates of P changing?
Most canola hybrid varieties grown today are capable of extracting large quantities of available soil and fertilizer phosphate (P) for seed production; however, P depletion rates far exceed current fertilizer P recommendations. ...
Effects of liming on soil pH and crop yield
The continuous use ammonium–based fertilizers in crop production have the tendency to acidify soils and threatened crop production in the long-term, leading to reduced crop yields. Conventional lime products used to remediate ...
