Effects of no-tillage and liming amendment combination on soil carbon and nitrogen mineralization

Popis výsledku v původním jazyce

Although no-tillage (NT), as opposed to traditional tillage (TT), and lime application are both common practices to increase productivity of degraded soils, our understanding of their interactive effects on C and N cyclig remains limited. Structural Equation Model (SEM) provides the opportunity to assess the direct and indirect effect of each agronomic practice on soil biogeochemical processes and determine the causal links among studied variables. We investigated the causal relationships among soil chemical and biological properties and C and N mineralization rates as affected by tillage practices (NT versus TT) and liming amendment (sugar foam plus red gypsum versus no amendment) using SEM. The adoption of NT increased soil C content, microbial activity and C mineralization in the topsoil, while amendment increased soil pH and accelerated the N cycling. The SEM revealed that C mineralization was only affected by tillage practices while net N mineralization (NNM) was increased by NT adoption and
