Farm and Agricultural Land

Management of livestock manures and effluent is a serious concern for Hawai‘i. Environmental impacts include contamination of groundwater and surface water with nutrients such as nitrogen and phosphorus, as well as disease organisms from manures.

APTA is committed to assisting farmers in Hawai‘i in minimizing water pollution from animal feeding operations (AFOs). We offer expert consultancy on best management practices (BMPs) for nutrient and waste management, including storage solutions, dead animal management, clean water practices, prevention of animal contact with state waters, chemical handling, runoff control, and comprehensive water and soil sampling.
