Effects of simulated erosion and amendments on grain yield and quality of wheat
Field experiments were conducted in 1991 at Josephburg (Black Chernozem soil) and Cooking Lake (Gray Luvisol soil), Alberta, Canada, to determine the influence of depth of erosion (simulated-erosion approach by artificially ...
Influence of alfalfa in bromegrass-alfalfa mixtures on forage yield, protein yield, fertilizer N requirements, net returns, and energy performance
Field experiments were conducted at Lacombe and Eckville in central Alberta from 1993 to 1995 to determine the influence of alfalfa in bromegrass-alfalfa mixtures on forage yield, protein yield, fertilizer N requirements, ...
Impact of topography and nitrogen fertility on canola and wheat diseases
Precision farming technology may offer the ability to increase current levels of grain production per unit cost by improving the efficiency of inputs. Canola diseases such as Sclerotinia, Alternaria and blackleg and wheat ...
How to get the most of P fertilizer in alfalfa stands
Phosphorus (P) is relatively immobile in soil. Our previous research has shown that the majority of fertilizer P recovered in soil as extractable P remains in the top 5 cm layer, even after long-term annual applications ...
Impact of topography and management on diseases of canola and wheat
Crop productivity on hilly terrain may vary greatly from upper to lower slopes due to differences in fertility, moisture and micro-environment. Plant diseases are affected by these conditions, resulting in differences in ...
