We are currently working to develop guidance about practices that will protect water quality. This clean water guidance will identify practices that are most effective in achieving and maintaining water quality standards.

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.

The long-term benefits include an increase in soil productivity in the long run. Your plan could include soil sampling and assessment, your preferred nutrient management techniques, and investing in manure storage structures that can help avoid the risk of spills and water contamination.

Why is landscaping important?

Planting trees, shrubs and grasses along the edges of your fields to add as a conservation buffer can help prevent any runoff. This is especially helpful if you have a field that borders any body of water. These buffers will help absorb nutrients that may run off or can help filter nutrients before they reach the water.

How can humans limit agricultural runoff?

That said, humans can limit agricultural runoff by being careful not to over-water their crops and avoiding excessive pesticide use. Many farms have switched to drip irrigation to conserve water.

Why do farmers use drip irrigation?

Many farms have switched to drip irrigation to conserve water. It gives water directly to a plant’s root rather than the entire surrounding area. This change is one example of a relatively simple choice that could cut down on unnecessary water usage and prevent agricultural runoff.

What happens when water from rain, melted snow, or irrigation doesn’t sink into the soil?

Runoff happens when the water from rain, melted snow or irrigation doesn’t sink into the soil for proper absorption. Instead, it moves over the ground, picking up natural and artificial pollutants along the way. Eventually, those contaminants get deposited into coastal waterways, lakes, rivers and even underground sources of drinking water.

Why do we have 80% of marine pollution?

A relevant statistic to be aware of here is that 80% of marine pollution happens because of activities on land. There’s also a potential link between agricultural runoff and the “red tide” phenomenon that occurs when a toxic algae arrives, killing fish and causing skin and eye irritation for some people who decide to swim in the ocean.

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.
