'''Green manures''' are particular plants which are grown to improve the structure and/or the fertility of the soil. They break up heavy soils and improve [[drainage]]. They can help light soils hold more water. Different green manures have roots of differing depths. These can mine for different minerals in the soil, bring them to the surface and keep them there. Green manures of the [[Legume]] family increase [[Nitrogen]] in the soil which will benefit the following crop. Some, such as [[Alfalfa]], root down very deep and bring up [[minerals]] to the top layer of the soil. The green tops, when dug in, add [[humus]] and [[nutrients]].
Turn the plants into the soil at the appropriate time for each variety. Some Green Manures can be clipped during their season and these clippings can be left on the soil to be dug in eventually to improve the [[tilth]] still further.
Overwintered Green Manures, such as Alfalfa, [[Tares]] and [[Ryegrass]], will keep the ground covered and so protect the soil and help prevent the leaching of nutrients.
If used in a [[rotation]] system, check the family of plants being used. [[Red Clover]], for example, being a Legume would fit into a rotation in place of [[beans]], and would be followed by a leafy vegetable such as [[spinach]] or [[lettuce]].
==MAIN GROWING SEASON==
Sow a quick-growing Green manure (such as Mustard, Buckwheat or Fenugreek), fitted in before sowing a second vegetable crop on that patch of ground.
==LATE SUMMER==
Sow a Green manure that will keep the ground covered and protected over the winter (such as Red Clover, [[Field Beans]], Alfalfa, Tares, Annual Ryegrass or [[Phacelia]])
