Biohumus and zeolite effect on irrigated meadow-grey soils fertility and bean performance

During the period of the research, the productivity of irrigated meadow-grey (in WRB - Irragic Calsisols) soils and the economic efficiency of beans were studied. Schemes used in practice: 1. control (without fertilizers); 2. biohumus 5 t/ha; 3. zeolite 5 t/ha; 4. biohumus 5 t/ha + zeolite 5 t/ha; 5. biohumus 7.5 t/ha; 6. zeolite 7.5 t/ha; 4. biohumus 7.5 t/ha + zeolite 7.5 t/ha. Soil productivity and economic efficiency of beans differed significantly depending on the rate of applied biohumus and zeolite. In bean cultivation, although the productivity was relatively high in the biohumus 7.5 t/ha + zeolite 7.5 t/ha option, the biohumus 5 t/ha + zeolite 5 t/ha option was more economically efficient.
