Too much
In 100-year-old crop lands used for research, Illinois scientists found that 50 years of massive nitrogen fertilization reduced corn yields and that level of organic carbon in the soil was greatly diminished, which leads to greater drought vulnerability. Conclusion? Lower doses of fertilizer often are better for crops, soil, water and air.
