Which animal management practice is mandated by Pennsylvania's Nutrient Management Act for large producers?

The mandated practice under Pennsylvania's Nutrient Management Act for large producers is nutrient management planning. This requirement aims to prevent nutrient runoff into water sources and to optimize the use of nutrients in agricultural practices. By creating a nutrient management plan, producers can assess the nutrient needs of their crops and livestock while balancing those needs with environmental protection.

Such plans typically include soil testing, crop nutrient requirements, and application rates for manure and fertilizers, ensuring that nutrients are applied in a way that minimizes environmental impact and maximizes agricultural productivity. This comprehensive approach helps maintain soil health and prevents pollution, which are critical goals of effective agricultural management.
