Impact of tillage system, rotation, and fungicide application on field crop production (1998-2001)
The impact of tillage, rotation, and fungicides on diseases and seed yield of wheat, barley, field pea, flax and canola was determined in the second cycle of 3, 4-year rotations at Melfort between 1998 and 2001. A 4-replicate ...
Soil and crop response to injected liquid swine manure on two Gray Luvisols
Intensive livestock production is increasing in western Canada, and so is the need to dispose of the manure produced. In the last six years or so, the Saskatchewan Centre for Soil Research at the University of Saskatchewan ...
Optimizing yield and quality of canola seed with balanced fertilization in the Parkland Zone of western Canada
A number of field experiments were conducted from 1998 to 2001 (or are underway) in northeastern Saskatchewan to determine the effects of various rates (0 to 30 kg S/ha), sources (sulphate S – potassium sulphate and ammonium ...
Effectiveness of elemental S fertilizers on canola after three annual applications
Plants feed on sulphate-S, but now elemental S fertilizers (which cost less per unit of S than the sulphate-S fertilizers) are available for commercial use. The effectiveness of elemental S fertilizers depends on how quickly ...
Unconventional methods of fertilizer placement to reduce losses of fall applied nitrogen
In two field experiments conducted in 1978-79, fall application of incorporated urea, or banded aqua ammonia, produced much less increase in yield and N-uptake than did spring application for barley grain. However, when ...
The rate of oxidation of elemental sulphur fertilizers
Uncropped field experiments were begun in June, 1979, and continued from 12 to 15 weeks after the addition of sulphur fertilizer on three soils, to determine the rate of conversion of elemental sulphur to soluble sulphate. ...
