METHOD OF SETTING VALUES OF PYROGENIC CHANGE IN PEAT LAYER THICKNESS ON PLOT OF RECLAIMED LANDS

摘要

FIELD: agriculture.;SUBSTANCE: method includes device of cutting, measurement of parameters of soil layer and calculation. In the layer of peat ash the mass of diatomic algae shells is measured per one unit of plot area. The value of pyrogenic change of peat layer thickness is calculated by the following formula: H=α·m, where H - is the value of pyrogenic change of peat layer thickness, cm; α - is the coefficient, cm·m²/g; n - is mass of diatomic algae shells per unit of plot area, g/m². The coefficient α is evaluate according to the formula: α=H₁/m₁, where H₁ - is the peat layer thickness of the analogue plot, cm; and m₁ - is the mass of diatomic algae shells per unit of analogue plot area, g/m².;EFFECT: method enables calculate quickly and accurately the pyrogenic change value of peat layer thickness.;1 ex
