Description

Using diverse crop rotations, which include three or four different crops, is generally the most desirable crop production practice. However, in the drier regions of southern Alberta, the pea-wheat rotation offers a number of significant advantages. Wheat yields after pea are often higher than after wheat as a result of increased soil nitrogen (N) availability, higher amounts of stored soil water and reduced disease potential. With the pea-wheat rotation, the need for nitrogen fertilizer inputs for pea and wheat are greatly reduced and often eliminated. From an economic and agronomic standpoint, the pea-wheat rotation can often be very profitable for southern Alberta dryland farmers.

Crop rotations in direct seeding

Description

Crop rotations are a vital part of direct seeding systems. Rotations maximize the benefits of moisture conservation and reduce the impacts of diseases, weeds and insect pests.

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.
