As the long-term studies, the use of humates not only leads to environmental improvement and detoxification of contaminated land, but also to improve the productivity of plants and improve their quality. We investigated the effect of humates different manufacturers on the yield and quality of different potato varieties. Experience laid in 2008 in Solnechnogorsky district of Moscow region on the territory of training experimental soil-ecological center of Moscow State University on sod-podzolic cultural medium loamy on moraine deposits soil. This area belongs to the Non-chernozem zone. The main part of it is occupied by a sod-podzolic soils, which have a low level of fertility by natural features of their genesis. These soils are poor in organic matter, therefore, have limited capacity to meet the needs of plants in nitrogen from its own resources. There is little phosphorus, potassium and other plant nutrients in it. The goal of our study is to investigate the effect of non-traditional organic fertilizers (humates) on yield and quality of potatoes. To achieve the goal we have been identified the following tasks:  To determine the yield of the following grades: "Bryansk novelty", "Santa", "Lasunak";  Assess the impact of humate fertilizer type on the quality of potato tubers of these varieties.
