5 Objectives (2003) 1. Determine if mnure mngement pln pproches provide sufficient crop nutrient requirements for optiml grin yield. 2. Compre soil P build up when following N or P bsed mngement plns. 3. Compre Nitrogen crry over when following either fertilizer or mnure mngement pproches Bord of Regents, South Dkot Stte University

6 Long Term Mnure Studies Tretments: 1. Check no fertilizer or mnure. 2. Rec recommended fertilizer bsed on soil test levels. 3. Mn P mnure rte pplied to supply crop P needs or replce removed P. 4. Mn N mnure rte pplied to meet crop N needs. 5. Mn 2N mnure pplied t 2X rte of tretment High Fert higher rtes of fertilizer nutrients (N,P,K,S nd Zn) 2014 Bord of Regents, South Dkot Stte University

24 Mnure mintined soil ph. However, inorgnic fertilizer decresed the soil ph s compred to mnure nd control tretments. Mnure ppliction incresed the SOC for ll the soil depths t either site s compred to inorgnic fertilizer nd control tretments. A similr trend ws observed for the TN, EC, WAS. Overll, the ppliction of mnure helps in improving the soil qulity indictors s compred to tht of inorgnic fertilizer.
