Effect of hog manure on soil phosphorus forms
Application of livestock manure can benefit crop production as a valuable source of nitrogen (Bandel and Fox 1984; Campbell et al. 1986; Chase et al. 1991). However, phosphorus is not a negligible factor as phosphorus in ...
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 ...
Assessing soil K supply capacity for wheat growth
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 ...
Assessing nutrient availability variations in landscapes
A simple method was developed to assess the variability in nutrient availability in undulating landscapes using anion-exchange resin strip burial. Resin strips were buried in ten farm fields along transects at points in ...
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 ...
