Linking groundwater quality to soil properties, landscape characteristics, and farm practice a spatial analysis of the "groundwater characterization in R.M. of Leroy" dataset
(2006-03-02)
The objectives of this study are to determine the source and extent of nitrogen and phosphorus contamination in the Rural Municipality of Leroy, and the most likely modes of contaminant transport, using only existing data. ...
Agronomic and economic benefits of fertilizing crops
(2006-03-02)
Operating costs at farm level can be divided into essential, enhancement, maintenance, protection and insurance. Save growth hormones, which are not common in western Canada, fertilizer and better quality of seed are the ...
Strategies for improving soil fertility in mature alfalfa stands
(2005-02-17)
Declining soil fertility is one of the main causes for decreased yields in mature alfalfa stands. Nitrogen, phosphorous, and sulphur are three nutrients that are often found to be limiting in prairie soils. In this study ...
Factors limiting soil microbial growth and activity in wheat-based cropping systems
(2004-02-19)
Several soil biochemical processes related to soil fertility are microbially mediated. We know
very well the factors limiting crop production but know little of the factors limiting the soil
microbial community. The goal ...
Barley after hay: grass matters!
(2003-02-18)
Perennial forage crops are not traditionally grown in crop rotations in the Brown soil
zone for several reasons: i) they are slow to establish; ii) they require intensive tillage to
terminate; and iii) they reduce yield ...
Effect of DDGS manure on soil and plant: preliminary results of the greenhouse study
(2009-02-26)
The use of dried distillers’ grains with solubles (DDGS) in feedlot cattle diets is increasing as the
bio-ethanol industry expands. Manure derived from dried distiller’s grain with solubles (DDGS)
fed cattle seem to have ...
Mustard is better suited to the warmer and drier semiarid prairie than canola
(2002-02-20)
Canola is a risky crop in the warm and dry semiarid prairie. Mustard is reported to be less susceptible to stress, although very little evidence is available to support this view. Nitrogen is the second most important ...
How hungry is hemp for fertilizers?
(2002-02-20)
A field experiment was conducted at Melfort, SK in 2000 and 2001 to determine the effects of nitrogen and phosphorus fertilizer rates on hemp (Cannabis sativa L.) productivity. Increased nitrogen fertilizer rates significantly ...
Effect of soil amended with thin stillage on growth of canola and soil properties in a controlled environment study
(2009-02-25)
A growth chamber study was conducted to evaluate the potential use of thin stillage as a soil
fertilizer amendment. Seven treatments; control, 3 thin stillage rates (100, 200, and 400 kg N
ha¯¹) and 3 urea rates (100, ...
Fertilizer-N management and nitrous oxide emissions from four sites in Saskatchewan
(2006-03-02)
Nitrous oxide (N2O) is a powerful greenhouse gas that also depletes stratospheric ozone. The use of fertilizer-N for agricultural purposes is thought to contribute significantly to Canadian anthropogenic N2O emissions. ...
