Reduction in tillage of the fields in order to reduce runoffs, soil compaction and erosion.
How can we reduce nutrient runoff?
Buffer strips of native grasses, plants, or turf reduce nitrogen and phosphorous in runoff water. Buffer areas receiving infrequent irrigation and fertilization provide a filter for nutrients from surface runoff water. The dense vegetation of a buffer slows runoff and allows time for water to infiltrate into the soil.
What is an example of agricultural runoff?
Agricultural runoff flows into the lakes and rivers that hundreds of towns draw their water from. For example, herbicide runoff from a farm in Centralia, Mo., might end up in Goodwater Creek, which empties into the Salt River, which then flows into Mark Twain Lake.

What is the leading source of impairments to surveyed rivers and lakes?
The U.S. Environmental Protection Agency (EPA) says this runoff is the leading source of impairments to surveyed rivers and lakes. Complicating matters is the fact that there’s no single source of this kind of runoff — farmers can’t just make one change to solve the problem.
How can farmers address the problem of cattle?
Two ways that farmers could address that problem are to fence cattle off from local rivers and lakes and to buffer pasture lands with bushes and trees. The potential for agricultural runoff is one impact of meat that people don’t often consider.
How does runoff affect agriculture?
Soil and nutrient loss and runoff from agricultural fields are major problems environmentally and economically in the U.S. and globally. After heavy spring rains, soil and water runoff containing fertilizer and pesticides is washed downstream, carrying the sediment and chemicals to the Gulf of Mexico. This process creates a large oxygen-starved area which is toxic to aquatic organisms and damages the commercial fishing and tourism industries. Tree-based buffers are an effective method for preventing runoff, however they can negatively affect crop yields. Based on years of research, University of Missouri scientists suggest farmers use buffers between crops and trees; this technique reduces soil runoff and maintains good growing conditions, creating economic benefits for farmers and, ultimately, for society in general.
Why are tree buffers important?
It is clear that tree-based buffers are an effective method to prevent soil runoff and can be an important strategy to protect farmland and downstream ecology and water quality ,” lead researcher Ranjith Udawatta said. “Finding the best ways to use tree buffers effectively while still maintaining high crop yields is imperative for the long-term success of the agricultural economy.”
