Many alternatives for the proper disposal of horticultural plant wastes have been studied, and composting
is one of the most attractive due to its insignificant environmental impact and low cost. The
quality of compost for agronomical use is related to the degree of organic matter maturation and stabilization.
Traditional parameters as well as temperature, ratio C/N, cationic exchange capacity,
extractable carbon, or evolution of humificated substances have been successfully used to assess compost
maturity and stability. However, microorganisms frequently isolated during composting release a wide
range of hydrolytic enzymes, whose activity could apparently give interesting information on the rate of
decomposition of organic matter and, therefore, on the product stability. The aim of this work was to
study the evolution of some important enzymatic activities during composting of agricultural wastes and
their comparison with other chemical parameters commonly employed as quality...
