Description

The Agricultural Land Resource Atlas of Alberta is a collection of agricultural resource maps developed following the completion of a scan of environmental issues facing agriculture in Alberta. The maps were prepared as part of this process, or were added to the collection because of their potential value to Alberta's agricultural community. The maps were recognized for their value to people involved in developing environmental farm plans who could use resource and environmental information on a broad scale.

Description

Grassed waterways are broad, shallow channels that carry surface runoff with a minimum of erosion. Natural waterways are easily seeded to forages, either grass or grass-legume mixtures, to prevent severe soil loss and gully formation. These waterways are constructed with uniform grades to gradually carry water down slopes and with flat bottoms to spread the water out and slow it. The vegetation in the channel retards the flow and provides a more durable channel surface that resists the soil cutting action of water. With proper fertilization and maintenance, a grassed waterway can be a productive forage area. Reshaping and grassing a gully allows easy access and crossing for machinery.

Description

Use emergency control measures if wind erosion is imminent or as soon as the soil starts to blow. Select the appropriate measure based on the soil condition. Some measures involve creating ridges at right angles to the prevailing wind. Others involve covering the soil with straw or manure. Once erosion has been brought under control, monitor the field. If the field begins to erode again, take further control measures. Emergency control measures are not a long-term solution to wind erosion. Preventive measures, such as maintaining a crop residue cover, adding field shelterbelts or growing perennial crops, are essential to protect the soil.

Description

Soil erosion has been long been recognized as a potential problem in Alberta. Prior to this study, focus had been mainly on soil erosion caused by wind. This study looks at water erosion in Alberta, and investigates the use of Universal Soil Loss Equation (USLE) as a method for assessing water erosion. This report describes the adaptation of USLE factors to Alberta conditions. A major modification was made to the precipitation component to recognize the contribution of spring snow melt.
