FIELD: agrochemistry, plant growing. SUBSTANCE: clinoptilolite-base artificial soil is obtained by mixing cationite and anionite at definite ratio followed by equilibration of the obtained mixture with solution of nutrient substances mixture. Anionite: material obtaining by the successive treatment of clinoptilolite firstly with magnesium salt at 50 C, not less, and then - with alkaline metal or ammonium hydrophosphate at 35 C, not above.
