Greater soil C inputs accelerate loss of C in cropping systems with low N input

BACKGROUND AND AIMS: Managing soil organic matter (SOM) levels in agricultural systems has focused predominantly on the quantity of plant residues returned to the soil but residue quality may also affect SOM stores and dynamics. Our objective in this research was to evaluate the influence of crop ro...
