Organic Matter

Green Manure cover crops have been the standard in cover cropping for quite some time.  A few favorites in this category are Merced Rye, Barley, Triticale, and other blends including various varieties of peas, beans, and vetch. 

Farmers seem to like these blends for the large amount of green material that is produced above ground. 

Although they provide easy establishment and sufficient erosion control, green manure cover crops have many drawbacks.  These drawbacks include frequent mowing, shallow root systems (dependent upon mix), little nitrogen fixation, and volunteer crops.
