Which animals are primarily monitored under the Nutrient Management Law in Delaware?

The selection highlighting livestock, including poultry, dairy, and beef cattle, is correct because these categories represent the primary focus of nutrient management regulations in Delaware. The Nutrient Management Law was established to address the environmental impacts of agricultural practices, particularly in relation to nutrient runoff and water quality. Livestock operations generate significant amounts of manure, which, if not managed appropriately, can lead to excessive nutrient loading in nearby water bodies. Monitoring these animals helps ensure that the nutrients from their waste are applied at levels that crops can utilize without degrading the soil and water resources.

In contrast, other animals like pigs, sheep, turkeys, ducks, fish, and amphibians, while important in the context of agriculture and ecology, do not fall under the specific provisions of the Nutrient Management Law in Delaware. The law is primarily concerned with the larger livestock operations that have a more substantial impact on nutrient management and environmental health.
