U.S. Department of Agriculture to Showcase Conservation Practices on Farmland

The U.S. Department of Agriculture (USDA) will expand outreach and innovative conservation practices on farmland in three small watersheds in Maryland, Pennsylvania and Virginia to show how focusing funding, sound science and strong partnerships in small geographic areas can help improve the health of local waterways and ultimately the Chesapeake Bay.

The three small watersheds, called “showcase watersheds,” are:

  •     The 23,000-acre upper Chester River watershed on Maryland’s Eastern Shore
  •     The 34,000-acre Conewago Creek watershed in central Pennsylvania
  •     The 67,000-acre Smith Creek watershed in Virginia’s Shenandoah Valley

USDA’s goal is to reach out to all of the farmers in each watershed to learn about the types of voluntary conservation practices they are currently using and to let them know about opportunities for financial and technical assistance.

Each watershed has its own restoration goals and will receive additional funding and staff to help increase the use of agricultural conservation practices on local farms. The U.S. Environmental Protection Agency is also contributing funding, and the U.S. Geological Survey will conduct local water monitoring. Local watershed groups and nonprofits are also involved in the efforts.

The showcase watersheds concept is part of the USDA’s plan to implement new conservation practices on four million acres of farmland in the Bay watershed by 2025, a commitment included in the federal government’s recently released Strategy for Restoration and Protection of the Chesapeake Bay Watershed.

“The showcase watersheds strengthen USDA’s commitment to funding priority conservation practices in places that will do the most good for water quality in the Bay and its tributaries,” said USDA Deputy Secretary Kathleen Merrigan at an event to announce the showcase watersheds.

The USDA’s Bay watershed work is funded in large part by the Chesapeake Bay Watershed Initiative, which was established in the 2008 Farm Bill and provides $188 million from 2009-2012.

Turning Over to No-till

Agricultural practices account for roughly one-quarter of the land use in the Bay watershed. Of that land, approximately 17 percent is devoted to crop production, which contributes significant amounts of nutrients and sediment to the Bay and its tributaries. But an increasing number of farmers in the Bay watershed are turning to a new, more Bay-friendly method of crop production called “no-till” farming.

Traditionally, cropland is fertilized and plowed in the spring to turn over the soil and prepare a good seedbed for planting. However, strong, frequent spring rains cause stormwater to rush across bare crop fields, which do not yet have plants to stabilize the soil and absorb the fertilizer. Excess nutrients and sediment from fertilizers and freshly plowed fields run off into surrounding waterways, eventually winding up in the Bay.

No-till farming, also known as conservation tillage or zero-tillage, leaves the soil undisturbed from the fall harvest to spring planting. Seeds are planted in very narrow slots that are “drilled” into the ground using disk openers, or coulters.

There are many benefits of no-till farming compared with traditional methods, including:

  •     Decreased rate of soil erosion and nutrient runoff.
  •     Increase in soil's organic matter.
  •     Improvement in soil's ability to soak up precipitation.
  •     Reduction of farm equipment fuel consumption by up to 50 percent.

No-till farming is considered such a critical part of Bay restoration that several no-till programs have recently received Chesapeake Bay Targeted Watershed Grants, funded by the National Fish and Wildlife Foundation and the U.S. Environmental Protection Agency. These grants help organizations implement innovative programs to reduce the amount of nitrogen, phosphorous and sediment that flow into the Bay.

In 2006, the Pennsylvania Department of Environmental Protection - in partnership with Penn State Cooperative Extension, USDA's Natural Resources Conservation Service, the Capital Area RC&D Council, the Chesapeake Bay Foundation and the Pennsylvania Environmental Council - received a grant to oversee the conversion of 12,750 acres of cropland to continuous no-till agriculture. This conversion will reduce the annual nitrogen load to the Susquehanna River by over 99,000 pounds, and the annual phosphorous load by over 17,000 pounds.

Farmers and landowners interested in no-till farming can contact their local USDA Natural Resources Conservation Service (NRCS) office for more information.
