The use of natural zeolites impregnated with zinc and copper ammoniates as carriers of micronutrients in growing vegetables

Abstract

The aim of our study was to obtain prolonged micronutrients for use in organic agriculture and production of row materials for baby food. For this purpose, we proposed to use impregnated with ammoniates of zinc and copper zeolite. Field experiments were conducted during 2011-2012 on the territory of Kyiv region. Results of two-year experiments revealed that during the first year of impregnated zeolite implementation statistically reliable (confidence level 0.95) increase of zinc and copper in carrot and beetroot. On the second year after zeolite implementation, their influence on zinc and copper concentration in spring oats and spring barley grains was observed. Concentration of these micronutrients in oats and barley grains was significantly larger than in the control sample. Implementation of zeolites, impregnated with zinc and copper ammoniates, can be recommended for improving the soil quality and micronutrients level in grain and vegetable production.
