Description

Of all the crops seeded on the prairies, field peas are often said to be the most easily adapted to direct seeding. For this reason, a large percentage of the pea acreage is direct seeded. Whether in a direct or conventional seeding system, the field pea crop requires close observation for disease throughout the growing season. Several economically important diseases can affect field peas.

Estimating the value of crop residues

Description

Crop residues - straw plus chaff - are the byproducts of harvesting annual grain crops. Retaining crop residues on a field improves or maintains soil quality and moisture. The economic value of... More ≫

Description

Crop residues - straw plus chaff - are the byproducts of harvesting annual grain crops. Retaining crop residues on a field improves or maintains soil quality and moisture. The economic value of retaining or removing crop residues from the field depends on the following: present level of soil organic matter; field's soil erosion risk; nutrient levels in the residues and soil; soil's moisture content; value of using the residues for other purposes such as bedding, coarse feed or industrial uses such as fibreboard; effects of any problems caused by poorly spread or heavy residues (such as the need for extra field operations)

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.

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.
