One way to manage sewage sludge, which is consistent with the assumptions of European Green Deal, use it in agriculture. The study focused on possibility using soil enzyme activity and GMea index (the geometric mean activities) connection total organic carbon (TOC) nitrogen (TN) content assess quality fallow light after exogenous matter (EOM) fertilization. Exogenous form stabilized municipal sludge was introduced into soil. experiment included five variants: one control site four sites 30, 75, 150, 300 Mg ha−1 added contents TOC, TN heavy metals (Zn, Cu, Pb, Cd) material were assayed. In addition, enzymes, i.e., neutral phosphatase, urease, protease dehydrogenase, examined, activities (GMea index) calculated. Fertilization resulted an increase TOC proportionally EOM dose. addition increased tested did not exceed levels considered acceptable. introduction contributed stimulation biological life This evidenced by intensification activity. However, individual enzymes showed a different response fertilization, while significant fallowed soils as rate 150 ha−1.
