Applicability of the indicator method for the determination of dynamics of the soil profile density against the background of gravimetric procedures

Commonly used gravimetric; method of determining soil density was compared under laboratory conditions with the indicator method developed at the Department of Soil Cultivation and Fertilization Techniques, IUNG Jelcz-Laskowice. The tests were carried out on artificial soil profiles with four degrees of compaction. Differences in the soil density determined with respective methods were in most eases contained within the limits of the measurement error. Discrepancies of the results obtained with the methods compared were decreasing along an increasing degree of soil density and thickness of the layer measured. The results obtained encourage to acknowledge the indicator method tested as an applicable measuring device lbr the density dynamics of soil profile.
