Long-term effects of no tillage and Ca-amendment on the activity of soil proteases and ß-glucosidase in a Mediterranean agricultural field

Popis výsledku v původním jazyce

The depolymerization of organic proteinaceous compounds is a critical step of nitrogen cycling in many agroecosystems, but our understanding of this process and the overall effect on N cycling is still limited. We have investigated long-term impacts of tillage practices and Ca-amendment on the activity of soil casein protease, BAA protease and glucosidase in relation with organic matter pools and the composition of extractable soil organic matter. While the adoption of NT increased the glucosidase activity and the total and extractable organic C contents in the soil, only casein protease was increased by NT in the upper soil layer. In contrast, Ca-amended plots showed higher casein protease and a lower BAA protease activity while glucosidase was unaffected. The decrease of BAA protease activity could be due to the reduction of easily extractable glomalin-related soil protein caused by amendment and highlights the tight relations between soil protease and glomalin. The imbalance in enzymatic activity
