Using organic amendments in fertilization offers a range of benefits, one of which is the reduced risk of nutrient leaching. Organic materials, such as compost or well-rotted manure, have a more complex structure than synthetic fertilizers, which results in slower nutrient release. This slower release allows nutrients to remain available in the soil for an extended period, reducing the likelihood that they will be washed away by rain or irrigation. When nutrients leach, they can contaminate groundwater and surface water, leading to pollution and nutrient imbalances in aquatic ecosystems. The use of organic amendments helps maintain soil health, promotes better moisture retention, and enhances soil structure, further contributing to the prevention of nutrient loss.

Immediate nutrient release, higher toxicity to pests, and lower cost than synthetic fertilizers do not capture the primary environmental and agronomic advantages organic amendments provide in the context of reducing nutrient leaching.
