ABSTRACT. The gross content of Manganese in soils of agricultural grounds of Central Siberia fluctuates from 45.4 to 3336.0 mg/kg. The concentration and distribution of manganese in regional soils depend on different conditions of soil formation, distinctions in particle size and mineralogical distribution and concentration of the element in soil-making layer. The background concentration of manganese in soils on the area of 2.54 million hectares is equal to 463.0 mg/kg or 0.5 Clark. The amount of mobile manganese in soils depends on reaction of the environment, oxidative- re-covering potential, the gross contents, particle size distribution, conditions of moistening and biological features of crops. In regional soils the content of mobile manganese fluctuates from 4.2 to 19.4 mg/kg or 2.0–3.0% of the gross contents. On the area of 2.22 million hectares (87.3%) in soils of agricultural grounds of the region the deficiency of mobile manganese is noted. The concentration of manganese in different crops depends on weather conditions, proper-ties of soils, mobile form of the element and biological features of plants. The concentration of manganese in grain yield, forage and vegetable crops fluctuates from 8.5 to 120.9 mg/kg. In forest-steppe, steppe and subtaiga zones of Central Siberia in forage crops the deficiency of manganese is noted. The improvement of quality of vegetable production on soils with the low and average content of mobile manganese requires rational use of organic and manganese fertilizers.
