The micronutrient and trace element status of crops grown on the Alberta soil quality benchmark sites

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... More ≫

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

This manual was prepared for Alberta crop producers to create greater understanding of beneficial environmental practices for crop production. It was developed through the cooperation of government, industry, and interested stakeholders. Information presented in this manual is based on the best available research data and years of experience. The manual provides a range of management options so producers can choose those alternatives best suited to their own operation.

Sustainable crop rotations for Alberta's brown soil zone

Description

In the Brown soil zone of southeastern Alberta, summerfallow and a monoculture wheat systems are the primary cropping practice. However, the long-term environmental sustainability of cropping... More ≫

Description

In the Brown soil zone of southeastern Alberta, summerfallow and a monoculture wheat systems are the primary cropping practice. However, the long-term environmental sustainability of cropping systems that include summerfallow remains in question. This fact sheet summarizes the results of a study that was undertaken to determine the effects of different cropping practices on soil quality in the long-term, and to determine the economic performance of several crop rotation alternatives in the Brown soil zone.

Grasshoppers are a major pest of both cultivated crops and rangeland grasses in the world’s semi-arid regions. Traditionally drier areas like southern Alberta are more prone to recurring problems,... More ≫

Description

Grasshoppers are a major pest of both cultivated crops and rangeland grasses in the world’s semi-arid regions. Traditionally drier areas like southern Alberta are more prone to recurring problems, but serious grasshopper infestations can occur in cropland throughout the province. Although the majority of grasshopper damage has been to cereal grains, other crops can be seriously affected. This fact sheet provides information on significant species of grasshoppers in Alberta, including each specie’s significant food supply. Information is also provide on grasshopper control and the economic threshold at which control measures become viable.

Description

This publication presents farm data taken from the 2001 Census of Agriculture, conducted on May 15, 2001. The data is specific to Alberta, and unlike an earlier spring release by Statistics Canada, targets a lower level of geography, namely, county, municipality, and improvement district. The data for this lower level of geography was obtained through a special custom run from Statistics Canada.

Description

This fact sheet describes some of the pathogens (diseases), insect predators and parasites attacking field crop insect pests. Natural enemies are those organisms that help control population levels of pest insects. Predatory insects, such as the lady beetles, eat many prey insects during their development. Lady beetles are just one example of the many different insects that prey, in both larval and adult stages, on other insects. Blister beetles, on the other hand, are predacious only as larvae; the adults are foliage feeders.

Description

Proper nutrition is essential for satisfactory crop growth and production. The use of soil tests can help to determine the status of plant available nutrients to develop fertilizer recommendations to achieve optimum crop production. The profit potential for farmers depends on producing enough crop per acre to keep production costs below the selling price. Efficient application of the correct types and amounts of fertilizers for the supply of nutrients is an important part of achieving profitable yields.

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.
