METHOD OF CONTROL OF EFFICIENCY OF RECLAMATION OF DISTURBED TUNDRA SOILS OF DIFFERENT PARTICLE-SIZE DISTRIBUTION BY ANALYSING ACTIVITY OF DEHYDROGENASE Russian patent published in 2013 - IPC B09C1/00 A01B79/02 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of ecology and soil science. The method includes the application of peat in the soils and control over their fertility restoration. At the first stage the particle-size distribution of disturbed soil is determined, such as by pyrophosphate method, and the doses of peat are established depending on the particle-size distribution of soils. Then the samples of peat are taken - sample No 1, of disturbed soil - sample No 2, and disturbed soil with the addition of peat - sample No 3. The activity of the enzyme dehydrogenase of the taken samples in the dynamics is determined not less than every 10 days and for not more than 40 days. At that, the start of reclamation of disturbed soil with a dose of peat is judged according to increase in dehydrogenase activity of sample No 3 relative to the dehydrogenase activity of the sample No 2. The completion of reclamation is judged according to leveling the dehydrogenase activity of sample No 3 with the dehydrogenases activity of sample No 1.

EFFECT: method enables to reduce the time of control of efficiency of reclamation of disturbed soils with different particle-size distribution, and to use rationally peat in the conditions of Far North.
