Project

The role of nutrient availability in microbial soil organic matter formation and stabilization in agricultural soils of different C saturation status (GA19-17139S)

and efficiency and SOM accumulation in soils differing in C saturation status. We will further asses total soil C balance and the composition and stability of the formed SOM.The soil organic matt...
