Yield trends of wheat – impact of fertilization and legume
A long-term (34-yr) crop rotation experiment being conducted at Indian Head, Saskatchewan, on a thin Black Chernozem with heavy clay texture, was used to assess the influence of fertilizer (N and P), sweetclover green ...
Olsen-P distribution in a thin Black Chernozem as influenced by fertilizers and crop rotations
Inorganic phosphorus (P) is generally believed to be relatively immobile in Chernozemic soils. However, available P (e.g., Olsen-P) has been found at depth in some soils and this has been postulated to be either the result ...
Predicting the amount of nitrate-nitrogen and water in the soil profile
Four simulation models were used to predict the amount and distribution of nitrate-N and water in soil from long-term spring wheat (Triticum aestivum L.) rotations at the end of the 1990 growing season at Melfort, Saskatchewan. ...
The effect of organic structures on the water stability of macro-aggregates.
A study was conducted to identify the chemical structures of soil organic matter and examine their effect on the water stability of macro-aggregates (>250 um) in a SiL Brown Chernozem under wheat-fallow (WF) and continuous ...
Soil organic matter on the prairies – a dwindling resource
Eighteen prairie surface soils (representing cultivated and uncultivated coarse-, medium-, and fine-textured soils) from the Brown, Dark Brown, Thin Black, and Gray Soil Zones were analyzed for changes in total carbon, ...
Swift Current rotation study after 12 years – yield, protein, and N uptake
This study was established in 1966 by the late Dr. W.S. Ferguson and Mr. C. Hank Anderson on Wood Mountain loam (Orthic Brown Chernozem) on land that had been in a cereal cropping system since 1922. The main objectives ...
