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.
Highlights
Ukraine has vast areas of fertile lands
Natural zeolite is widely used in agriculture since due to its unique properties it improves the soil quality, capable of retaining the moisture and reducing the mobility of pollutants
The crop increase is observed in both zeolite variants - (Var 2) and (Var 3) - comparing to the control (Var 1)
Summary
Ukraine has vast areas of fertile lands. The most fertile soils in the world – humus soils – occupy almost 27.8 million ha, which is 67.7% of total arable Ukrainian lands and 8.7% of all world humus (Pozniak, 2008). Availability of large areas of fertile lands enables the development of organic agriculture production. Total area of certified for organic farming agricultural lands is of 270226 ha. Ukraine is ranked first in the east-European region by the area of lands certified for organic farming. These farms specialize mostly on production of Received 07 March 2013; Revised 17 April 2013; Accepted 10 May 2013; Published Online 25 August 2013
