The mathematical modeling of mobile zinc and cobalt level in soil

Abstract

Abstract According to the research results, the coefficients of applied zinc and cobalt fertilizers activity are calculated. It is established that each kilogram of zinc and cobalt applied into the soil layer of 0-30 cm increases the level of mobile zinc by 0.012 and 0.013 mg/kg of soil, mobile form of cobalt by 0.028 and 0.025 mg/kg of soil.
