What are the benefits of green manures?
Green manures have many advantages but have two key roles: they add organic matter to soil, and make nitrogen and other nutrients available to the next crop. Some crops such as legumes fix N into the soil. Others mop up available nitrate from the soil and release it over many months after incorporation, especially good for wheat or brassica crops.
Should green manures be destroyed before setting seed?
All summer green manures must be destroyed before setting seed. Inter cropping is the growing of a green manure at the same time as a cash crop. Seed is sown into a newly established cereal or brassica crop, usually in the spring, and left underneath until the main crop is harvested.
These quick growing green manures are fast to establish. They are short term, lasting between two and six months. They can be sown on their own between cash crops or as an understory to a main crop. They are sown to add organic matter, fix nitrogen and suppress weeds.
When to plant winter hardy green manure?
