METHOD OF DETERMINING AVERAGE DEGREE OF RESTORATION OF PEAT SOILS

摘要

FIELD: agriculture.;SUBSTANCE: method includes sampling of peat and vegetation growing on it. The samples of peat and vegetation are incinerated and the total content of Mn and Cr is determined in the ash. Biohpility of metals is calculated by the following formulae: A_Mn=Mn_vegetation:Mn_peat and A_cr=Cr_vegetation:Cr_peat. The average degree of restoration of peat soil K_Red is calculated by the formula: K_Red=A_Mn:A_Cr.;EFFECT: method enables to determine quickly and accurately the average reductive-oxidative conditions in peat.;1 tbl, 1 ex
