The effect of redevelopment of the deposits on the fertility of dark-gray soil in the forest-steppe zone of the Krasnoyarsk Natural District was shown. The studies were carried out on the soil catena established by geomorphological profile of the deposit massif on the slope of the eastern ex- posure with a slope. Three points were identified geochemically conjugated to each other, 1.5-2.0located in different parts of the slope: the top, flat- tened middle and the foot of the slope. A part of the array of deposits on the slope was processed and introduced into arable land with planting potatoes. During vegetation season of 2016-2017 an as- sessment of moisture regime, temperature and soil supply with the main nutrients (nitrate and ammoni- um nitrogen, mobile phosphorus and exchangeable potassium) was given. Spatial variation of all indica- tors for judging qualitative state of the ecosystem of clean and fallow land deposited as well as for the purpose of methodologically reasonable compari- son of the objects of study was investigated...
