A method to forecast provision of soils with micronutrients includes taking samples, analysing thereof and forecasting the content of micronutrients in the soil according to mathematical models. The average content of carbon of humic acids (C) and fulvic acids (C) is determined in the samples. Based on statistical-mathematical analysis, regression equations are obtained. According to said equations, the forecasted content of MN (CMN), for example Zn (1) and Mn (2), is determined:Y() = 0.852 – 0.466X + 0.071X, (1)Y() = 53.887-28.371X + 3.974X, (2) |
