Description

Broadcast methods of applying swine manure to fields create odour problems and result in significant losses of valuable crop nutrients to the air. Research has shown that up to 30 per cent of the usable nitrogen may be lost. This research update reports on a cultivator-based high-volume injection system developed by the Prairie Agricultural Machinery Institute to maximize the fertilizer value of liquid swine manure.

Description

Soft white spring wheat responds well to fertilizer when grown on soils low in plant available nutrients. Nitrogen (N) fertilizer can dramatically increase yield, and under certain conditions, it will increase the protein content of the grain. The ideal protein level of soft wheat should be less than 10.5 per cent, for optimum baking quality. For soft wheat growers, the challenge is to apply sufficient nitrogen fertilizer and irrigation water to achieve optimum yield and still maintain a protein content of less than 10.5 per cent. Other nutrients such as phosphorus, potassium, sulphur and micronutrients will also have an effect on the growth of soft wheat.

Description

Home composting is a way of recycling kitchen and yard wastes safely and simply in your own back yard. Composting speeds up the natural breakdown of organic material into particles and nutrients. These particles and nutrients contribute to better growing conditions for plants by breaking up heavy soils, increasing soil nutrient content and helping soil retain air and water.

Description

The cultivation of prairie soils has generally resulted in a decline in organic matter of 30 to 50 per cent. A product of this decline has been the release of large amounts of plant nutrients, particularly nitrogen. Crop rotations with a high frequency of summerfallow have relied on the nitrogen released from soil organic matter to supply crop requirements. More frequent or continuous cropping, less frequent tillage, the production of high yields and the return of crop residues will help to maintain soil organic matter at a satisfactory level. Perennial forages are effective for maintaining or increasing soil organic matter.
