Fertilizer placement affects nutrient leaching patterns

Controlled-release fertilizers (CRFs) are a widely used method of delivering nutrients to nursery container crops. The fertilizers contain encapsulated solid mineral nutrients that dissolve slowly in water, and are then released into substrates over an extended period of time. Although the use of CRFs is an accepted practice, growers and researchers are always looking for ways to decrease fertilizer and irrigation expenses and reduce the impact of nutrient leaching into the environment. A new study contains recommendations for CRF placement methods that can address these issues.
