Using oil industry waste effectively to improve an eroded loamy sand
As depletion of the easily recoverable oil reserves in western Canada accelerates, the volumes of waste generated during heavy oil production and processing are steadily increasing. The 600 million litres of heavy oil ...
Manure, crops, and soil health
Biomass accumulation and nutrient uptake of oilseeds at different growth stages in the parkland region of Saskatchewan
Field experiments were conducted with canola (Brassica napus and B. rapa, cv. Quantum and Tobin), mustard (cv. AC Vulcan) and flax (cv. Norlin) in 1998 and 1999 at Melfort, Saskatchewan, Canada, to determine biomass and ...
Influence of hog manure and fertilize N on P supply rate in soil and uptake by canola under controlled environment conditions
The effect of manure and urea on P availability to canola was investigated under controlled environment condition. Canola (B. napus) was grown in pots with manure and urea added to two Saskatchewan soils (sandy loam and ...
Can the quality of soil structure be maintained following repeated applications of high rates of hog manure?
The long-term impact of repeated applications of high rates of liquid hog manure on the quality of the soil and that of the environment is not well known. For optimal application rates of hog manure, improved knowledge is ...
Chemical changes in cereal straw under two fallow systems and its relationship to nutrient availability
In recent years, conventional mechanical fallow has been partly replaced by herbicide-fallow on the prairies. With the chemical system of weed control, the straw is not mixed with the soil until seeding the following spring; ...
