Soil N mineralization involves an upstream cascade of depolymerization rxn, largely amino-N (i.e., peptides, amino sugars).
1. Are enzyme activities that catalyze N depolymerization sensitive to pH? Yes.
2. Are currently assumed pH optima correct? No.

Illinois landowners & producers, we seek your help in identifying contact and permissions to re-sample locations at which soils were originally sampled across the state as far back as the late 1800s. Map here: google.com/maps/d/u/1/vie…

New test plots at the College of ACES will be over 70 times the size of the current Morrow Plots. Andrew Margenot shares plans for the 'living lab' and how the new plots will shape the next 150 years of research: bit.ly/49qkwS7 #FWN

Does synthetic nitrogen fertilizer burn up soil organic matter?
Multiple studies say NO.

N fertilizer actually slows loss of old soil organic matter and increases microbial biomass and new soil organic matter.
