DYNAMICS OF INDICATORS OF SOIL ACIDITY AFTER LIMING
Тhe degree of pH in KCl is quite convenient parameter for evaluation of soil acidity. It is fast to define, and can serve a good indicator of favourable reaction of the soil environment for the growth of plants and determination of liming need. The concrete parameters of pH changes with a change in dose of lime, initial pH and humus content were identified. Under laboratory conditions, using a CaCO3 maximum pH shift was achieved in the first 10 days of the experiment. When dolomite or defecate were used a slight increase in pH was noted even 40 days after application, and 90 days later a decrease of pH in all tested forms of lime was recorded. Parameters of lime consumption for the specific shift the pH value and its prediction were offered.
