Conteúdo: |
Concern over groundwater contamination from agricultural chemicals has increased in recent years, and nitrates from heavy nitrogen fertilizer applications on small grain are a frequently accused culprit. However, tests by the Alabama Agricultural Experiment Station indicate that leaching of nitrogen (N) fertilizers is not a major problem. Nitrates leached into the subsoil by N fertilizers are in the tenths of a part per million range and nitrate from organic matter is only a few parts per million. |
