FIELD: agriculture.SUBSTANCE: method of improvement of fertility of soil for tree and grass cultures comprising the extraction of silt from places of its formation, and after production of silt it is treated to remove excess moisture content, then it is packed into containers for consequent transportation and before planting of woody plants or grass cultures in soil a trench is made, and there the layers of extracted silt and removed soil are laid sequentially, and then tree or grass cultures are planted, meanwhile a trench is formed between longitudinal rows of tree cultures down to the lower level of fertile soil, and sequential backfilling of layers of extracted silt and removed soil is performed after the beginning of forming of the trench, then in places of backfilling of silt and removed soil the holes are formed periodically, which are filled by water and injected by biological organisms for conversion of silt and increase of soil fertility.EFFECT: invention allows to reduce a work cycle of forming of soil fertility.2 dwg |
