EFFICIENCY ASSESSMENT METHODOLOGY APPLICATIONS OF PHOSPHOGYPSE IN AGRICULTURE
A new method for assessing the efficiency of using phosphogypsum in agriculture has been developed. The methodology is based on the general properties of plant growth curves established in field and vegetation experiments on crops of cereals, potatoes, and other crops, as well as the dependences obtained in the study of soil moisture during alkaline soils cleavage, etc. In the mathematical model, it is assumed that the yield ( Y ) and its addition increase with an increase in the amount of growth factor ( X ), are proportional to the amount of the yield ( A - Y ), which does not reach the maximum limit value ( A ) and the possible value yield ( B + Y ), above some minimum initial value ( B ) yield. The article contains general formulas that allow finding the value of the “coefficient of action of the growth factor”. Examples of finding the “coefficient of action of a growth factor” when using phosphogypsum on potato crops and calculating the effectiveness of using phosphogypsum in alkaline soils are considered.
