NOVELTY - Method for preparing organic nutrient soil, involves selecting manures of sheep and cattle fed by natural forage, grinding the dried sheep and cattle manures, adding water, stirring the mixture, subjecting the mixture to natural anaerobic fermentation or industrial biological aerobic fermentation, inactivating all worm eggs, harmful germs and weed seeds in the mixture to obtain final dark brown-colored product without any odor, and adding the obtained product with sand and natural peat in a ratio of 10-50:20-70:10-30 with respect to crop.    USE - The method is useful for preparing organic nutrient soil (claimed).    ADVANTAGE - The usage method enables planting without any geographical restrictions, adjusts row and plant spacing during planting with respect to growth spacing, is environmentally-friendly, prevents fertilizer leakage, enables drip irrigation, sprinkler irrigation, infiltration irrigation or flood irrigation for watering methods, maintains and content to 40-50 based on different crops, environment temperature and environment humidity.    DETAILED DESCRIPTION - Method for preparing organic nutrient soil, involves selecting 80% manures of sheep and 20% cattle fed by natural forage as raw fertilizer sources and nutrient sources, where the natural forage is grass grown naturally and never been applied with pesticides, chemical fertilizers or artificial additives, and the sheep manure comprises sheep urine which is rich in organic nutrients to stabilize plant growth, grinding the dried sheep and cattle manures to mesh size of 0.2-0.5 mm, adding water to obtain moisture content of 55 plus minus 5%, stirring the mixture, subjecting the mixture to natural anaerobic fermentation or industrial biological aerobic fermentation, inactivating all worm eggs, harmful germs and weed seeds in the mixture to obtain final dark brown-colored product without any odor and adding the obtained product with sand and natural peat in a ratio of 10-50:20-70:10-30 with respect to crop, where plants grown in the above-mentioned nutrient soil meets all technical indicators of organic food standards. An INDEPENDENT CLAIM is included for method for using the organic nutrient soil, which is by taking semi-closed cultivation tank having width of 50-150 cm and height of 20-40 cm used for planting, sealing all inner surfaces of the cultivation tank using plastic sheet with proper thickness to isolate from soil and surroundings excluding portion used for planting, adding the organic nutrient soil to a thickness of 15-40 cm into the tank, and transplanting seedling to the tank, where the length of the tank is determined with respect to size of the greenhouse, and height of plants, and the solanaceous vegetables requires thickness of the soil of 40 cm.
