True or False: Changes to manure management systems that affect nutrient content require an amendment.

The statement is true because any changes to manure management systems that significantly affect the nutrient content necessitate an amendment to the nutrient management plan. This requirement is in place to ensure that nutrient applications are managed correctly and that the levels of nutrients being applied to the land accurately reflect current practices. Keeping the nutrient management plan updated and reflective of any changes ensures compliance with state regulations and helps in the sustainable management of nutrients to minimize environmental impact.

Failure to amend the nutrient management plan when changes occur could lead to misunderstandings regarding nutrient application rates, potentially causing excess nutrient runoff or crop deficiencies. Hence, any modifications that alter the nutrient profile of the manure must be documented through an amendment process to maintain the integrity and effectiveness of the nutrient management strategy.
