We bale the soybean stubble off of our fields. After grinding and bagging it is ready to sell.
It is quite a process, but it is a great product and offers many benefits. It helps the soil retain moisture and is great protection for the plants because it has a higher retention level. With typical cedar mulch, people experience a greater amount of loss due to wind, but this is less of a problem with the soybean mulch. After several years of using soybean mulch, it also improves the quality of the soil.
