Abstract

In the work of the tracked changes in the content of water-soluble organic substances (WSOS) 5 years after liming acid soddy-podzolic sandy loam soil with different doses of ameliorant (conversion of chalk). It is revealed that in the embodiment of experience with evidence-based dose of ameliorant number C orgue, extracted with water at room temperature has not changed, and when extracted with boiling water decreased by 24%. When using the ameliorant in a dose of 2.5 hydrolytic acidity (H a) output C orgue, extracted with water at t = 20°C, increased by 17%, extractable with boiling water was reduced by 22%. It is shown that increasing the dose of chalk 2.7 times increased loss of WSOS migration to 1.19 times. When the 1-3 rd washing, regardless of the variants of the experiment, there was a sharp decrease in the content C orgue by the exponential type. Starting with the 4 th flushing, marked by complex nonlinear dynamics of the studied indicator. The proposed empirical model adequately describing the general trend of the dynamics washed WSOS. The index of the optical density of the eluate WSOS (Е с т §/ т 1), percolating through the soil was typical for solutions of fulvic acids and changed regardless of experience option from 0.4 to 2.2 units.
