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 ...
Developing simplified synergistic relationships to model topsoil erosion and crop yield
Topsoil is highly enriched with organic matter, which provides a valuable source of plant nutrients as well as a favorable rooting environment. Over time, erosion processes selectively remove the organic matter-rich fine ...
The effect of winter feeding systems on nutrients, forages, cattle, and economics
Extensive and intensive cattle feeding methods were compared for their effect on nutrient distribution, pasture growth, cattle parameters, and economics. In the extensive system cattle were fed on the pasture by either ...
Effect of repeated additions of liquid swine manure and solid cattle manure on soil organic carbon
The agronomic effects of liquid swine manure and solid cattle manure application on soil nitrogen (N) and crop yield in Saskatchewan soils has been well documented (Mooleki et al. 2002b, Mooleki et al. 2004). However, the ...
