Description

Crop micronutrient concentrations of both vegetative tissues and grain, if applicable, were measured from 17 selected AESA soil quality benchmark sites in the fall of 2003. Micronutrients analyzed included boron, cadmium, chlorine, copper, iron, manganese, molybdenum, nickel, selenium, silicon and zinc. The purpose of this report is to provide an account of these micronutrient concentrations and to correlate them with a number of selected soil properties including soil pH, organic carbon, sand, silt and clay content, cation exchange capacity and calcium carbonate concentrations. In addition, the uptake, translocation and importance of each micronutrient are discussed, as is a summary of the effect of micronutrient partitioning between the grain and straw fraction, the effect of landscape form and the effect of provincial ecoregion on their concentration.

Description

The need for micronutrients in crop production have long been recognized in Alberta. Zinc deficiencies in irrigated beans in southern Alberta were detected in the early 1980s. Research by Alberta Agriculture and Agriculture Canada has clearly shown the need for copper fertilizer particularly for wheat grown on organic soils and on some Black and Grey-Black soils in central Alberta. One million acres may be copper deficient in central Alberta. Some suspected manganese deficiencies are presently being investigated. Continued research and testing is required to identify when various crops will give economic yield increases to additions of micronutrient fertilizers.
