You Can Reduce Nitrogen Pollution 1. Use Organic Fertilizers Organic fertilizers do not contribute to the nitrogen glut because they use recycled nitrogen. Also, the nitrogen in organic fertilizers is insoluble and is released to the plants slowly over time.
Synthetic fertilizers are water-soluble and can be easily washed away into lakes and streams.
Your Soil Find out what level of nitrogen and other nutrients your soil already has. Follow the soil test recommendations, using organic fertilizers. Call your local extension service to find out how to test your soil. Also, never apply fertilizer to frozen ground, it will wash away when the ice melts. Or better yet, grow your own.
