FIELD: agriculture.
SUBSTANCE: inventions relate to agriculture. Method of modifying soil texture and improving profile of concentration of nutrients includes: obtaining discrete particles of mineral substance obtained from coal, separated from discrete unburnt particles of coal, wherein particles of mineral substance are fire-resistant, and coal particles are combustible, and before separation from unburnt coal particles, mineral substance particles are found among coal particles inherent to coal; and mixing mineral particles with soil. Soil enhancer for modifying soil texture and improving profile of nutrient concentration. Improved soil, having modified soil texture and improved profile of nutrient concentration. Method of improvement of cation-exchange capacity (CEC) of soil.
EFFECT: invention increases content of sludge and clay in soil, increases availability of mineral and necessary nutrients for plant growth.
