Hog and cattle manure additions in the Black Soil Zone of Saskatchewan: agronomic considerations
Experiments were conducted in 1997 at two sites (Burr and Dixon) in the Black soil zone, east - central Saskatchewan, to examine the effects of different rates and methods of application of swine and cattle manure applied ...
Phosphorus loading and environmental analysis in manured Saskatchewan soils
Phosphorus (P) is a key element in plant nutrition, but excessive amounts can accumulate in the soil if manure P application rates exceed crop uptake over time. Risk of potential P movement and contamination of surface ...
Ion-exchange resin strips as plant root simulators
Ion-exchange resin strips have the potential to closely mimic the manner in which a plant root removes nutrient ions from the surrounding soil. A method was developed involving burial of resin strips in soil; followed by ...
Use of ion-exchange membranes in routine soil testing
We developed and assessed a method for simultaneous ·extraction of plant available nitrogen, phosphorus, sulfur, and potassium using anion- and cation-exchange membranes (ACEM). The technique was found to be highly suitable ...
Swine manure as a source of plant nutrients
Influence of urease and nitrification inhibitors on ammonium and nitrate supply and the soil microbial population in western Canadian soils
Improving nitrogen use efficiency and limiting losses of N from the soil system is important both economically and environmentally. This study assessed the potential of using a urease inhibitor, Agrotain®, or a nitrification ...
Soil respiration and nitrous oxide production in distillers grain and glycerol amended soil
Applying by-products of biofuel production to soil may be an alternative use to take direct advantage of nutrients and carbon contained within. Ethanol production results in distiller grain and biodiesel produces glycerol ...
