Abstract:

The presented data were collected at the experimental fields of the Institute of Agriculture in Skopje, Republic of Macedonia during
2008 and 2009. The experiment with corn plant was conducted to study the effect of fertilizer Mega green on some elements in
corn grain (hybrid ZP 677, FAO 600). Mega green is ecological foliar fertilizer made of calcite, micronized by a new tribomechanical
technology. Main components are: CaCO3: 82.3%; Si�?2: 5.56%; MgO: 3.02%; CaO: 41.7%; Fe: 8783 mg/kg; Mn: 156 mg/kg; Se: 0.24
mg/kg. Foliar treatments consisted of three levels of Mega green with in a concentration of 0.3, 0.6 and 0.9 percent and control variant
(without fertilizing). The experiment was carried out on two different experimental sites on alluvial soils. Soil samples (0-20 and 20-
40 cm depths) were collected to determinate the chemical properties of the experimental field. During the harvest, the samples of
corn grain were taken for chemical analysis from each variant. The soil and plant analysis were made carried out according officially
adopted international methods. The statistical analyses showed significant positive effect of foliar applications of Mega green in
concentration of 0.9 % on the content of K, Mn and Zn in corn grain. The concentration of these elements in grain samples for the
2008 and 2009 growing seasons was as follows: K- 0.27 and 0.29%; Mn-5 and 6 mg/kg and Zn-22 and 26.33 mg/kg. The findings
showed that effects of Mega green on the P (0.18-0.20 %), Ca (0.13-0.15%), Mg (0.07-0.08%) and Fe (23.5-25.66 mg/kg) concentration
in the grain were insignificant. Results showed the high relationship between some macro and microelements in corn grain. A
significant positive correlation was found between concentration of Ca (like main fertilizer component) and Fe and Cu. Mega green
applications in the both years of our research showed significant negative correlations between Ca and N concentration.
