If you garden, do lawn maintenance, or farm, you’ve probably added nitrogen fertilizer to your soil. Nitrogen is the most common nutrient to limit plant growth – because plants need quite a lot of it (10-60 g per kg of plant mass, to be exact). It also doesn’t stick around very long in the soil. Instead, it ends up in places where we don’t want it: in groundwater, water bodies, and even the atmosphere.
But, why? And how can we get nitrogen to stay in the soil, where plants need it?
