Effect of Herbicides on Field Violet (Viola arvensis) in Direct-Seeded Spring Wheat1
The agrestal field violet, a pervasive weed in Europe, has been identified in reduced-tillage cereal fields in Alberta and management of the weed does not appear to cause significant crop production losses; hence, herbicide selection should be based on knowledge of all weed species present within the field.

Soil N loss is a significant impediment to maximizing yield and profitability for farmers in Canada. Maintaining N in the stable and plant-available NH4 + form via use of nitrification inhibitors… Expand
The reaction of iron chlorides with some aliphatic primary amines
Abstract The reaction at room temperature of iron (III) chloride with excess of several primary amines has been studied. With each primary amine (NH2R, R Me, Et, Prn and Bun) reduction to iron (II)… Expand
