It was found that high fertilization used in greenhouse cultivation of crops causes a significant increase of the elements and other nutrients not only in arable layer, but also in the deeper layers of soil. The range of changes in the chemical properties of investigated soil depends more on length of greenhouse utilization and on the accepted production program than on the soil texture. The extent and depth of soil contamination in greenhouses proves that it is necessary to propagate close system of fertilization
