Organic fertilization loosens the soil,promotes soil life, regulates the water balance and increases overall soil fertility.
The effect of mineral fertilization depends on the sufficient supply of organic substances. Humus enables soil bacteria to develop, -fungi and other small creatures, which in turn converts the nutrients present in the soil into a form that plants can absorb. The humus substances lead to better aeration and heat storage in the soil and thus promote the root growth of the plants. In addition to compost, there are also stable manure as organic fertilizers, liquid manure, Peat, bark waste, sewage sludge, Leaves and green manure available. Vegetable land should receive organic fertilization every two years, where about 300 kg manure or 600 kg of compost 100 m2 are to be deployed. Green manure roughly corresponds to normal stable manure application.
