Answer:
Adopting Nutrient Management Techniques: Farmers can improve nutrient management practices by applying nutrients (fertilizer and manure) in the right amount, at the right time of year, with the right method and with the right placement.2,3
Ensuring Year-Round Ground Cover: Farmers can plant cover crops4 or perennial species5 to prevent periods of bare ground on farm fields when the soil (and the nutrients it contains) are most susceptible to erosion and loss into waterways.
Planting Field Buffers: Farmers can plant trees, shrubs and grasses along the edges of fields; this is especially important for a field that borders water bodies. Planted buffers can help prevent nutrient loss from fields by absorbing or filtering out nutrients before they reach a water body.6
Implementing Conservation Tillage: Farmers can reduce how often and how intensely the fields are tilled. Doing so can help to reduce erosion, runoff and soil compaction, and therefore the chance of nutrients reaching waterways.7
Managing Livestock Access to Streams: Farmers and ranchers can install fence along streams, rivers and lakes to block access from animals to help restore stream banks and prevent excess nutrients from entering the water.8
Engaging in Watershed Efforts: The collaboration of a wide range of people, stakeholders and organizations across an entire watershed is vital to reducing nutrient pollution to our water and air. Farmers can play an important leadership role in these efforts when they get involved and engage with their State governments, farm organizations, conservation groups, educational institutions, non-profit organizations, and community groups.
