What can I do with spent mushroom compost after the crop?

Spent mushroom compost is far from waste and is one of the nicer side benefits of mushroom growing. After the crop, the leftover compost is a useful organic manure and soil conditioner that can be returned to your fields, vegetable beds or orchard to improve soil structure and add organic matter, after a little curing or composting to mature it. Some growers also sell it to nearby vegetable, horticulture or nursery growers as an organic soil amendment, so it can bring a small extra income rather than being thrown away. It can also go into vermicompost or general farm compost. Avoid using very fresh spent compost straight on sensitive seedlings, and let it mature first. So plan to recycle it back into your farm or sell it locally as organic manure. Your KVK can advise on the best local use and any treatment before field application.
