Tavdishvili, L. (Research Institute for Horticulture, Viticulture and Wine-Making) Georgia
The indices of crop increase in Red soils samples with the use of different forms of nitrogen fertilizers (Na, Nm, Naa) are not alite. With carbamite-72%, ammonium sulpate-60%, ammonium nitrate-67%. The use of different forms of nitrogen fertilizers favored to agrochemical indices of soil. Both macro and microelement supply was indicated but the lack of same elements was observed too. Specifically of Mg(6,1-3,1 mg/100g. dry substance). Mobile Mn content on PK background under the influence of nitrogen fertilizers increases twice.
