Fertilizer management in conservation tillage affects how plants absorb nutrients. No-tillage systems can reduce nitrate nitrogen in the soil by almost 50%. Phosphorus and potassium tend to stay near the surface in no-tillage systems, making them less mobile. Applying nitrogen fertilizers on the surface can lower the soil pH, especially in sandy soils. To maintain soil health, it's important to monitor pH levels and consider more frequent lime applications on sandy soils.
