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 ...
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 ...
X-ray absorption spectroscopic analysis of raw and processed hog manure
(2007-03-01)
Anaerobic digestion technology is a process that allows livestock producers to generate electricity and heat by digesting manure. Clear-Green Environmental Inc. uses this process to make biogas from hog manure. Raw manure ...
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. ...
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 ...
Examining the nutrient dynamics of willow biomass energy plantations
(2012-03-13)
Natural Resources Canada, along with a number of Canadian provinces, considers bioenergy to be a legitimate and sustainable source of energy that will constitute a significant portion of future energy production. Shrub ...
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. ...
Yield and protein of wheat and durum in Brown Soil Zone as affected by long-term tillage system and crop rotation
(2003-02-18)
Three tillage-rotation experiments in the Brown soil zone showed that spring wheat and durum grain yield and protein were affected by tillage system, length of time in tillage system, crop sequence. During the initial 15 ...
What agronomic practices can reduce the effect of Fusarium head blight on durum wheat in Saskatchewan?
(2005-02-17)
Fusarium head blight (FHB) has become an important disease of cereals in moist regions of western Canada. This disease has played an important role in contributing to lower grain yields and substantial downgrading of durum ...
