METHOD OF POLYFACTORIAL EXPERIMENTS FOR SUBSTANTIATION OF TECHNOLOGY OF CULTIVATING OF AGRICULTURED CROPS ON SOIL CONTAMINATED BY HEAVY METALS

V.G. Golovatyi, V.N. Buravtsev, E.A. Kotova

By the example tetraploid ryegrass the method was described of polyfactorial experiments and analysis of experimental data, permitted on the basis of numeral operations with the use of regression models to select the doses of fertilizations (NPK) for obtaining of standard pure production on the soils contaminated by the complex of heavy metals (Zn, Cu, Pb).

Key words: agricultural plants, polluted soil, heavy metals, complex vegetation experiment, numerical analysis, ridge analysis.
