FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, in particular to the closed and open ground plant cultivation nutrient substrates, which contain complete set of nutrients for plant growth in high concentrations and intended for long-term use without additional fertilizers application with watering with slightly mineralized water at the drinking norms level. Substrate consists of the potassium 10÷89 wt%, ammonium 20÷79 wt% and hydrogen 0÷30 wt% forms of natural clinoptilolite and calcium, magnesium sparingly soluble salts, and phosphoric and / or sulfuric acid 0÷10 wt% mixture. Substrate solubility provides the total ion concentration in the contacting substrate aqueous solution of 0.1÷50 mEq/dm3.
EFFECT: enabling creation of the environmentally friendly nutrient substrate for ionitoponics based on natural ionites, saturated with the biological ions complex, in equilibrium with water forming the nutrient solution.
