| Legume crop (no nitrogen application recommended) |
Lb N removed/unit of yield |
Lb N removed/A |
Comments |
|---|---|---|---|
| Alfalfa (5 ton/A) |
50 | 250 | Although legumes will use N from manure and other sources, applying N may increase the competition from weeds and grasses. If you apply manure, limit it to an application rate that balances the crop's P requirement. |
| Clover (3.5 ton/A) |
40 | 140 | Although legumes will use N from manure and other sources, applying N may increase the competition from weeds and grasses. If you apply manure, limit it to an application rate that balances the crop's P requirement. |
| Trefoil (3.5 ton/A) |
50 | 175 | Although legumes will use N from manure and other sources, applying N may increase the competition from weeds and grasses. If you apply manure, limit it to an application rate that balances the crop's P requirement. |
| Soybeans (40 bu/A) |
3.2 | 130 | Although legumes will use N from manure and other sources, applying N may increase the competition from weeds and grasses. If you apply manure, limit it to an application rate that balances the crop's P requirement. |
