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.

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.

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.
