EFFICACY FERTILIZERS FOR POTATOES ON SOD-PODZOLIC LOAMY SAND SOIL
Abstract
The оptimum system of the fertilizer of the potatoes is an using 50 t/hа organic fertilizers and mineral fertilizers in dose N80+40Р30K120. The most high productivity is received under such system of the fertilizer in experience club 256 ц/га at contents of the starch 16,2 %, net income 594,0 USD/ha and profitability 119 %. Specific stand bear main element of the feeding under given system of the fertilizer has formed: nitrogen - 7,1 kg/t, phosphorus - 2,9 kg/t, potassium - 14,8 kg/t.
