Wpływ polepszaczy glebowych zastosowanych w uprawie Medicago sativa na wybrane właściwości chemiczne i biologiczne gleby

The objective of this study was to determine the effect of selected calcium-based soil improvers applied to field-grown alfalfa (Fraver) on the some chemical and biological properties of soil. The research revealed that the application of the improvers noticeably increased the pH of soil and the content of magnesium. The influence of the soil improvers on the microbial and enzymatic properties of soil was equivocal. However, it can be concluded that this speciments increased the number of total bacteria and oligotrophs and the enzymatic activity of soil.
