Green manures
robust crops are used to improve and protect the soil. They are a valuable tool in a garden and should be included in plans for cultivation. The main benefits include improved use drainage, fertility, structure, water holding capacity and weed control.
retain nutrients in the soil preventing water drag. A time to reap the green manure and decompose returning nutrients to the soil for the next crop the advantage. They also provide extra protection to the soil in the surface layer, preserving the structure of heavy rains and other phenomena that cause soil erosion.
green manure crops.
In the case of legumes (beans, peas ...), they take nitrogen from the air by increasing soil fertility, making them an interesting option.
can be grown in any season, from spring through fall.
The soil is prepared as any other plant, from the rake to the ground is level and then broadcast the seed sown or planted in small grooves. Should be mowed and get into the soil before it becomes rock hard and more difficult decomposition and in the case of annual green manure must be before they bloom. Forbs such as clover can be pruned when they bloom. Before planting allowed to spend about 4 weeks to allow time for the compost to decompose.
When it's time to incorporate green manure, mowing with a sickle or mulching and use a shovel or hoe to plunge the plants in the ground. You can put up mowing once a layer of compost or mulch to avoid having to bury the green manure.
The most used are: vetch, fodder bean, pea, lentil, black oats, rye, mustard and turnip rape and annual forage species such as white clover, red clover and alfalfa.
Grasses are generally interesting for its rapid growth and have deep roots that till the ground and steal nutrients from the bottom to deposit on the surface, with particular emphasis on rye has the ability to improve sandy and clay soils and dig deep.
legumes as mentioned have the power to obtain N from the air to fix to the surface. They are also effective against weeds. It is interesting to joint planting of several species: legumes & grasses to deepen the land while protecting the surface and provide nutrients.
