| | Taking a New Look at Green Manure Crops (Site not responding. Last check: ) |
 | | Green manure crops are grown for their green matter, which is incorporated into the soil. |
 | | Many crops can be used as green manures: annual species such as pea, lentil, chickling vetch, buckwheat, mustard, oilseed radish, and faba bean; winter annual species like fall rye and winter wheat; biennial species like sweet clover and red clover; and perennial species such as alfalfa and white clover. |
 | | Green manure crops, with their many biological roles, are useful in low-input cropping systems. |
