FIELD: agriculture.SUBSTANCE: method of improvement of fertility of soil for tree and grass cultures includes extraction of silt from places of its formation, after production of silt it is treated to remove excess moisture content and placed into containers for consequent transportation, 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, tree or grass cultures are planted. A trench is formed between longitudinal rows of tree cultures down to the lower level of fertile soil, then the troughs are stacked in one or several parallel sequences, above which at a capillary clearance a sequence of tightly connected plastic tubes with the lower long slots are located. The beginning of plastic tubes and their end are connected to the pipeline for supply of irrigation water and pipeline for air removal from plastic tubes, then layers of extracted silt and removed soil are sequentially backfilled and 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 improvement of soil fertility.EFFECT: improvement of soil fertility.2 dwg |
