- Intervention effect High-rate mineral N fertilizer in 1996-1997 resulted in high NO3 leachate concentrations of up to 34 mg N L(-1).
- Intervention effect High-rate mineral N fertilizer in 1996-1997 resulted in high NO3 losses of up to 56 kg N ha(-1) yr(-1).
- Intervention effect Manure plus mineral N fertilizer combinations resulted in high NO3 leachate concentrations in 1996-1997.
- Intervention effect Manure plus mineral N fertilizer combinations resulted in high NO3 losses in 1996-1997.
- Observation Nitrate leaching losses were relatively small in the other seasons.
- Intervention effect Nitrate leaching from sole manure treatments was relatively low, at less than 20 kg N ha(-1) yr(-1) on average.
- Intervention effect Combined manure and mineral N fertilizer enhanced crop uptake efficiency of mineral N fertilizer by up to 26%.
