What is the purpose of a nutrient management plan (NMP)?

A nutrient management plan (NMP) serves a crucial role in promoting sustainable agricultural practices. The primary purpose of an NMP is to outline how nutrients—such as fertilizers and organic materials—will be managed in a way that safeguards water quality. This involves assessing the nutrient requirements of crops, understanding the nutrient content of soils, and considering environmental factors that can influence nutrient runoff into nearby water bodies.

By documenting these management practices, the plan aims to minimize the risk of nutrient loading and pollution, ensuring that excess nutrients do not enter waterways, which can lead to issues like algal blooms and water quality degradation. This strategic approach not only supports crop health and productivity but also aligns agricultural practices with environmental stewardship.

In contrast, the other options do not focus on the core objectives of an NMP. Increasing pesticide use does not align with nutrient management and could potentially harm environmental health. Documenting nutrient management for health inspections might be a component of regulatory compliance but lacks the broader intent of actively protecting water quality. Listing all crops planted does not encompass the comprehensive planning and management aspect that an NMP provides related to nutrient usage and its environmental implications.
