Term Definitions

Best Management Practices (BMPs): Agricultural "Best Management Practices" for pollution control are management practices and structural measures which are determined to be the most effective, practicable means of controlling and preventing pollution from agricultural activities. BMPs are singular practices that, when put together in combination with other practices, will reduce soil erosion, nutrient and pesticide runoff or leaching, and manage animal manure. BMPs are actions taken by each individual agricultural operation to protect water quality while achieving production.

Resource Management System (RMS): combines management and conservation practices that, when installed, will prevent degradation and permit sustained use of the natural resources (soil, water, air, plants, animals) by meeting specific quality criteria.

Integrated Crop Management (ICM): A comprehensive system that involves considering the environment when selecting pesticides and nutrients. ICM emphasizes a more comprehensive systems approach toward agricultural production systems rather than concentrating on the benefits of individual practices. ICM is an informed decision-making process that takes into account production practices, economic, soil and water quality, and nutrient and pest management.

Tolerable Soil Loss value ("T"): The amount of soil loss that can be tolerated each year while still maintaining high soil productivity.
