7 Å, is identified Kaolinit. Some minerals have expressed characteristics of ad- sorption, as it is the case with some minerals of clay, so the soil with greater quantity of clay is from the side of plants bind in soil, while only smaller part gets to underneath water. However, in case of sandy soil, that have not so big capability of adsorption, we have to be careful while washing out not adopted nourishments on the nitrate basis, because their substrate can come to underneath water, that negatively influence on environment. Two different kind experiments of sorption characteristics of soil were conducted. Examining sobbing were done as difference of concentration of nitrate ion in solution be- fore and after passing through solution as well as extracting from soil after wetting with solution of certain concentration of nitrate. Those experiments were:
