【 摘 要 】
It was established that the mashed soils in the tundra zone have a light granulometric composition. The humus content in the washed soils of Bovanenkovo gas field does not exceed 0.8%. The humus content in the soil of the sand pit is even less - only 0.1%. Disturbed soils have low reserves of gross and mobile nitrogen, phosphorus and potassium, without additional application of which it is impossible to grow perennial grasses. An effective method of increasing the content of substances in the soil is the application of high standards of mineral fertilizers (N150P150K150). Ammonia nitrogen at low temperature is better absorbed than nitrate nitrogen. The use of peat biomes in combination with mineral fertilizers (N160P160K160) increases the content of nitrate nitrogen in the root layer of the soil 6.3 times, available phosphorus - 1.7 times, potassium - 3.7 times. Nitrate nitrogen is mainly accumulated in the layer where peat was introduced. Introduction to the sandy soil of 4-12 t/ha substrate of BIONE increases the amount of nitrate nitrogen 3.4-5.8 times, available phosphorus - 1.4-1.8 times, mobile potassium -3-4.1 times. Conditions of water and temperature regimes of disturbed soils of the far North and poverty in nutrients necessitate the application of multicomponent mixtures. Technologies of restoration of disturbed sandy soils after their technogenic disturbance in industrial development of the Far North are offered.
