In 1998, the Maryland General Assembly passed the “Maryland Nutrient Management Law” that requires certain agricultural operations, including horse farms, to obtain a nutrient management plan. This document is intended to help horse farm operators determine if a plan is needed for their farm and what basic steps are necessary to obtain a plan.
The Water Quality Improvement Act (WQIA), also known as the Maryland Nutrient Management Law, was passed in 1998 by the Maryland State Legislature. The goal of nutrient management planning is to reduce non-point source pollution (e.g., nitrogen and phosphorus from cropland) by balancing nutrient applications with crop nutrient requirements. Nutrient management planning, which is an array of best management practices (BMPs), is considered to be one of the most cost-effective means of controlling excessive nutrient applications.
