| cover cropping to reduce nitrate loss through subsurface drainage in the northern u.s. corn belt. | despite the use of best management practices for nitrogen (n) application rate and timing, significant losses of nitrate nitrogen (no3(-)-n) in drainage discharge continue to occur from row crop cropping systems. our objective was to determine whether a autumn-seeded winter rye (secale cereale l.) cover crop following corn (zea mays l.) would reduce no3(-)-n losses through subsurface tile drainage in a corn-soybean [glycine mar (l.) merr.] cropping system in the northern corn belt (usa) in a mod ... | 2004 | 15224938 |
