How can agricultural operations reduce nutrient pollution?

 · Unfortunately, negative effects of agricultural runoff are not limited to inland waters. Polluted waters also affect the oceans. According to the U.S. National Ocean Service, 80 per cent of pollution of the marine environment come from the land, and nonpoint source pollution from agricultural runoff is the major contributor [8].

What is the main cause of runoff pollution?

As a result of installing BMPs to reduce runoff, the feedlots and loafing areas will be drier, allowing farmers to manage their daily operations more easily. Animal health can improve due to reduced foot disease and other ailments. Note Proper runoff management can result in: Avoidance of stream pollution by phosphorus and other potential pollutants.

How can we prevent agricultural runoff pollution?

How does runoff affect agriculture?

As agricultural runoff enters bodies of water it can have negative impacts on the environment. Not only can it contaminate sources of drinking water but the chemicals in the fertilizers can be absorbed into aquatic plants, contribute to algae blooms and effect animals’ ability to find food and reproduce.

How can agricultural pollution be reduced?

Applying fertilizers in the proper amount, at the right time of year and with the right method can significantly reduce how much fertilizer reaches water bodies. Keeping animals and their waste out of streams keeps nitrogen and phosphorus out of the water and protects stream banks.

What is agricultural runoff and how can it be prevented?

Agricultural runoff is the flow of water that occurs when farm irrigation systems apply more water than the ground can absorb. Excessive irrigation can affect water quality by causing erosion, transporting nutrients, pesticides, and heavy metals.

What is agricultural runoff pollution?

Polluted runoff is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into watersheds through lakes, rivers, wetlands, coastal waters, and even our underground sources of drinking water.

What causes agricultural pollution?

Agricultural pollution has many different sources. Nitrogen-based fertilizers produce potent greenhouse gases and can overload waterways with dangerous pollutants; chemical pesticides with varying toxicological effects can contaminate our air and water or reside directly on our food.

How do farmers prevent fertilizer runoff?

Voluntary Conservation is Part of the Solution. Filter strips move row crop operations away from streams and function as collection centers for nutrient runoff. Cover crops reduce soil erosion and hold nutrients in place. No-till practices also reduce soil erosion and improve field-level water infiltration capacity.

Below are the top solutions to the Problems of Agriculture: Provision of Adequate Education to Farmers. … Provision Large Area of Land to Farmers. … Reducing of the Cost Farmer Inputs to Farmers. … Encouragement of the Gender and Age in Farming Sector. … Farmers should be Encourage to Join Co-operative Society.More items…•

Is agricultural runoff a point source of pollution?

As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground waters. Nonpoint source pollution can include: Excess fertilizers, herbicides and insecticides from agricultural lands and residential areas.

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.

How agricultural activities contribute to water pollution?

Agriculture, which accounts for 70 percent of water withdrawals worldwide, plays a major role in water pollution. Farms discharge large quantities of agrochemicals, organic matter, drug residues, sediments and saline drainage into water bodies.

How to collect irrigation runoff?

To collect irrigation runoff, French drains can be placed in the propagation area, along the lower perimeter of the nursery or garden center, and on the lower side of the nursery stock display area. Instead of large retention basins for holding irrigation runoff, something as simple as a concrete septic tank can be used. Small plastic pipe can be used for moving captured runoff in comparison to the 10- or 12-inch pipe that may be necessary for a larger nursery.

How does a capture and recycle system work?

Basically, a capture and recycle system has a network of channels and ditches that capture runoff irrigation water from the nursery beds, and divert it to basins that retain the water. The water can then be pumped from these retention basins back onto production areas or to a storage basin. Wholesale nurseries that irrigate with large volumes of water have large amounts of runoff to capture and recycle.

What is a retention basin?

In a larger capture and recycle system, retention basins are designed to retain runoff from the nursery and to collect and hold storm water. But, in an urban setting, retail nurseries may choose to divert storm water from off-site so they are not responsible for it. Although no storm water retention limits have been set for Oklahoma, other states require that the first one half to one inch of storm water falling on a nursery site be retained. Most rain events do not overflow the retention basins, but sometimes the discharge limit is exceeded. With careful management of the water levels in retention basins, any discharge will be diluted by off-site storm water. If storm water were not retained, the concentrations of pollutants in the early discharge from the nursery could be very high. Regulations concerning runoff from nurseries and garden centers vary from state to state, so check with local authorities such as the Oklahoma Department of Agriculture for additional information.

What is the Illinois River Irrigation Tailwater Project?

This program, the Illinois River Irrigation Tailwater Project, was initiated in 1989 in response to concerns about the irrigation tailwater leaving the nurseries, and the effects on the Illinois River and Lake Tenkiller if the releases were left uncontrolled. The project allowed the nurseries to work with the state department to control the quality of runoff water entering the scenic river and lake.

Why is it important to capture and recycle irrigation runoff?

Constraints on water availability, environmental initiatives, and increasing regulation have compelled ornamental growers and nurserymen to search for alternative water practices, such as capturing and recycling irrigation runoff. Capture and recycle technology began as a strategy to conserve water and to reduce water and energy costs. A recycling system may also control storm water. The cost of implementing a system depends on various factors such as the volume of runoff to be captured and topographic features that determine the number of retention basins needed to capture runoff.

How does runoff affect the environment?

Increases in nutrients, such as phosphorus, can lead to algal blooms and eutrophication of water bodies, while pesticides and herbicides can disturb biotic communities. Capturing and recycling irrig ation runoff can eliminate pollution of local water supplies by nurseries.

What are the disadvantages of a capture and recycle system?

Recycling irrigation water has several disadvantages. Building retention basins, waterways, and additional pumping stations to implement a capture and recycle system can be costly. Some of these costs can be offset by decreased water and fertilizer costs. There is also concern about the buildup of salts, herbicides, and pesticides in recycled irrigation water. The solution to these problems can be found with proper management. A high salt content can be solved through dilution with fresh water, while more precise application and thoughtful selection of pesticides and herbicides can reduce the total amount present in the system. Another problem associated with a capture and recycle system is the distribution of weed seeds that pass through sediment screens.

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 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 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.

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.

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.

When did farming start in Quebec?

Large-scale farming only began in Quebec in the 1950s, but data showed that some of the areas examined already reached the “tipping point” mentioned above by the 1920s.

What are the consequences of agricultural runoff?

Polluted agricultural runoff is a major source of water pollution globally. Agricultural runoff is primarily caused by melted snow or rainfall. It is, in essence, water that does not stay in the soil but instead flows on the surface and carries a variety of polluting elements.

What is runoff management?

Runoff management allows dairy farmers to direct rainwater and/or other runoff water away from their manure storage facilities and confined animal feeding areas. Benefits from runoff control include but are not limited to:

Why do barnyards need to be cleaned?

The barnyard/feedlot needs to be on a surface that can be cleaned so that manure may be removed. This limits the quantity of manure that could potentially be washed off. Providing a hard surface allows the cleaning operation to be done without forming pockets that can collect leachate or change the runoff flow.

Why are BMPs needed in the feedlot?

As a result of installing BMPs to reduce runoff, the feedlots and loafing areas will be drier, allowing farmers to manage their daily operations more easily.

Why should runoff water be collected?

The runoff water should be collected so that it can be stored or treated. If it is to be stored, gravity flow to an appropriately sized waste storage facility is preferred. If the runoff will be treated, pretreatment, by settling to remove most of the solids, and topography are suitable for improved barnyard/feedlot construction.

What keeps water clean in barnyard?

Roof gutters, surface water diversions and drip trenches can keep water clean, and away from the barnyard.

Why are buffers important in fields?

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. 9.

What happens to phosphorus and nitrogen in water?

This excess nitrogen and phosphorus can be washed from farm fields and into waterways during rain events and when snow melts, and can also leach through the soil and into groundwater over time. High levels of nitrogen and phosphorus can cause eutrophication of water bodies.

What nutrients do farmers use to grow food?

Farmers apply nutrients on their fields in the form of chemical fertilizers and animal manure, which provide crops with the nitrogen and phosphorus necessary to grow and produce the food we eat. However, when nitrogen and phosphorus are not fully utilized by the growing plants, they can be lost from the farm fields and negatively impact air …

What keeps nitrogen and phosphorus out of the water?

Keeping animals and their waste out of streams keeps nitrogen and phosphorus out of the water and protects stream banks.

What is conservation drainage?

Using Conservation Drainage Practices: Subsurface tile drainage is an important practice to manage water movement on and through many soils, typically in the Midwest. Drainage water can carry soluble forms of nitrogen and phosphorus, so strategies are needed to reduce nutrient loads while maintaining adequate drainage for crop production. Conservation drainage describes practices including modifying drainage system design and operation, woodchip bioreactors, saturated buffers, and modifications to the drainage ditch system. 5,6
