METHOD FOR OBTAINING ION EXCHANGE MIXTURE "REKULTIVIN" Russian patent published in 2017 - IPC C09K17/02 A01G31/00 

FIELD: agriculture.

SUBSTANCE: method for obtaining an ion-exchange mixture for permafrost soils is described. The method involves mixing 88 wt % of saturated clinoptilolite and 12 wt % of saturated anionite EDE-10P. Before mixing, initial clinoptilolite of the 0.3-0.4 mm fraction and anionite are subjected to pre-treatment which provides obtaining clinoptilolite saturated with specific biogenic cations and anionite saturated with certain ions of the biogenic elements. The invention provides an ion-exchange mixture saturated with the nutrient elements necessary for plants in the optimal ratio, taking into account the agrochemical properties of the initial permafrost soil.

EFFECT: introducing said ion-exchange mixture into the permafrost sandy soil in the norms of 4-12 t per 1 ha for perennial grasses during reclamation results in increasing the fertility of this soil due to increasing the nutrient content in this soil with increasing the content of humus, nitrate nitrogen, mobile forms of phosphorus and potassium, and with reducing the soil acidity.
