These seeds when grown and dug in can add nutrients,nitrogen and organic matter to the soil, so they are a useful
way of soil improvement to use, in addition to home made composts and manure especially if they are in short supply.
- Green manure seeds are selected from a range of seeds to suit the soil conditions you have. They are also planted not only to suit the soil conditions that you have but also to serve the purpose that you are sowing them for.
- Green manures - provide organic matter and nutrients, in the case of legumes they can provide nitrogen.
They also help to smother weeds and also they help to protect the surface of the soil and can help to stop the nutrients from being washed/leached out of the soil in the winter time. Green manure crops can also be used to produce materials for composting.
- How long the green manure crop is left growing in the ground depends on the type that is planted.
- When deciding which type to sow you need to keep in mind crop rotation patterns.
Different types of green manure plants suit different soil conditions and also help combat different problems -
