Dentrification and mineralization in soil amended with legume, grass, and corn residues

The dentrification dissimilatory NO3- reduction and nitrogen mineralization immobilization in a Brookston clay loan was studied to establish the effect of incorporating hairy vetch (HV, Vicia villosa), reed canarygrass (RCG, Phalaris arundinacea L.), annual ryegrass (AGR, Lolium multiflorum), red clover (RC, Trifolium pratense L.) and corn (Zea mays L.) residues. From the third to the fifth day of the aerobic inerbation, mineralization took place during the treatment of HV. During the anaerobic phase, nitrite was accumulated in all cases.
