Failure to simulate C and N mineralization in soil using biomass C-toN ratios as measured by the fumigation extraction method ?

Abstract

A C and N mineralization model (DETRAN) was used to simulate C and N dynamics in an unfertilized soil (NIL plot) and a soil annually fertilized with organic (FYM plot) or inorganic fertilizer (NPK plot). The soils amended with or without rye, i.e. 500 mg C and 30 mg N kgÿ1 dry soil (D.S.), were incubated for 180 d at 258C and microbial biomass C and N, CO2… (More)
