How does agriculture cause 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.

Why is it important for farmers to protect the environment?

Pasture and cropland occupy around 50 percent of the Earth’s habitable land and provide habitat and food for a multitude of species. When agricultural operations are sustainably managed, they can preserve and restore critical habitats, help protect watersheds, and improve soil health and water quality.

What are five environmental effects of agriculture?

Agriculture contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.

How can we stop nitrogen pollution?

We already know how to reduce our nitrogen footprint: use less nitrogen fertilizer, eat fewer energy-intensive foods, and try to minimize fuel-heavy forms of transportation, like airplane travel.

How can we prevent farm runoffs?

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.

How farmers can reduce water pollution?

Farmers can reduce NPS pollution from irrigation by improving water use efficiency. They can measure actual crop needs and apply only the amount of water required. Farmers may also choose to convert irrigation systems to higher efficiency equipment.

How can we reduce the use of fertilizers?

Agroforestry, mulching, intercropping, crop rotation, organic farming are management strategies to reduce chemical fertilizers usage.


What is agricultural pollution?

Agricultural pollution can be defined as the degradation or contamination of the environment through abiotic and biotic byproducts of farming. For many years, our ancestors did farming in a sustainable way, thus there were almost no problems with agricultural pollution.

How does agricultural pollution affect plants?

Agricultural pollution can become a problem for parts of the local plants since invasive species could impact the population of native species in an adverse way which in turn can change the dynamics of the whole ecosystem.

Why should farmers build fences around water bodies?

Farmers can build fences around water bodies in order to prevent access for animals and thus excessive amounts of nutrients enter the water. Although this is just a small measure in order to reduce agricultural pollution, it still is a small step in order to reach our goal of less pollution.

Why is animal waste important?

Animal waste is a big cause of agricultural pollution. Thus, it is crucial to set up and improve processes concerning the management of these pollutants. There are several manure treatment processes that aim to reduce the adverse impact of manure on the environmental system.

Why should farmers consider the reduction in the tillage of their fields?

Farmers should consider the reduction in the tillage of their fields in order to reduce runoffs, soil compaction and erosion. Thus, a more sustainable path towards farming and a reduction in agricultural pollution could be accomplished.

Why should farmers try to improve nutrition management?

Farmers should try to improve nutrition management so that fertilizer and pesticides are not used in excessive amounts in order to mitigate the agricultural pollution problem. This means to determine in a scientific way how much pesticides and fertilizer are necessary to get a reasonable crop yield.

How does fertilizer affect aquatic life?

Effects on aquatic life. There is also an adverse effect on the aquatic system from agricultural pollution. Since the excessive use of fertilizer can contaminate rivers with an excessive supply of nitrates and phosphates, the production of algae can be enhanced.

How can farmers improve nutrient management practices?

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. 3,4.

How can conservation tillage help the environment?

Implementing Conservation Tillage: Farmers can reduce how often and how intensely the fields are tilled. Doing so can help to improve soil health, and reduce erosion, runoff and soil compaction, and therefore the chance of nutrients reaching waterways through runoff. 10

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 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

What happens to fish in eutrophication?

Eutrophication can lead to hypoxia (“dead zones”), causing fish kills and a decrease in aquatic life. Excess nutrients can cause harmful algal blooms (HABs) in freshwater systems, which not only disrupt wildlife but can also produce toxins harmful to humans.

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.

Why is low input agriculture important?

Low-input agriculture aims to reduce levels of applied products, including fertilizers, to fields. Along with best management practices, it should help reduce both greenhouse gas production and the environmental impact of farming.

How to reduce nitrous oxide emissions?

We know that, in climates where the ground freezes, overwintering plants on the soil (that is, leaving plants intact on the soil surface after harvest instead of plowing them in or removing them in the fall) can help reduce nitrous oxide emissions.

How do plants affect soil temperature?

The insulating effect of leaving the plants on the ground surface will affect soil temperature. And the plants contribute nutrients that are added to the soil as they slowly decay during periods above freezing. It’s a complicated system, to be certain, and work into this subject is ongoing.

What is the process of methane production?

In nature, microorganisms known as methanogens convert simple forms of carbon to methane (CH4). Methane production, or methanogenesis, happens in the absence of oxygen. So waterlogged soils (such as bogs or rice paddies) tend to produce more methane, as do methanogens that live in the rumen (stomach) of ruminant animals, such as cows and sheep.

When fertilizer is added to soil, what happens?

When the amount of fertilizer added to a soil is more than can be taken up and used by plants, bursts of nitrous oxide are often produced. In climates where the ground freezes in winter, spring thaw is often accompanied by bursts of nitrous oxide production as well.

Why do farmers use fertilizer?

Providing nitrogen for their crops is one of the main reasons farmers apply fertilizer, whether organic or synthetic. A natural biological process called denitrification converts the nitrogen in fertilizer (in the form of nitrate or ammonium) to harmless nitrogen gas (N2, a major component in Earth’s atmosphere).

How does water vapor affect the atmosphere?

Water vapor levels depend on atmospheric temperature, which is in turn affected by levels of heat-trapping gases in the air. By reducing levels of other greenhouse gases in the air, we’ll also reduce the amount of heat-trapping water vapor produced via evaporation of surface water. This has implications for farms that use irrigation.

What are some examples of measures to reduce the risk of pollution at the farm steading?

2.6 Measures to reduce the risk of pollution at the farm steading (for example, improved collection and storage of silage effluent, slurry, fuel oil and pesticides) have successfully reduced the risk of direct discharges to rivers. Attention is now increasingly being focused on the activities being carried out in the fields.

How does farming affect the environment?

By applying these inputs in the right amounts and at the right time both farmers and the environment can benefit. Excess nutrients, such as nitrogen and phosphorus, can harm soils, rivers, lochs and estuaries by causing algal blooms and by changing the natural balance of plants, insects and other life. In the wrong place, pesticides can kill river insects and fish and can remain in river sediments for many years. Run-off from dirty yards, roads and grazing fields or land that has been spread with livestock slurries can also contribute to the bacterial contamination of inland and coastal waters and the failure of environmental quality standards. Fellow farmers downstream may experience poor quality water or incur extra expense in dealing with the effects of diffuse pollution including the possibility of disease transmission. In addition, groundwater (i.e. water held below the surface of the land; an important source of drinking water in rural areas) can be put at risk as a result of the leaching or percolation of nutrients and pesticides from the surface of the land. Groundwater is also important in maintaining river flow and for other aquatic environments. If it becomes polluted, surface waters are also at risk.

What are the risks of industrial waste?

2.17 Sewage sludge or industrial wastes can contain potentially toxic substances such as heavy metals and persistent organic chemicals which may contaminate soil and pollute rivers. Certain precautions must be taken and statutory obligations complied with. Analysis of the waste before use, assessing the land suitability prior to spreading, calculation of the growing crop requirements, soil sampling and nutrient budgeting can all reduce the risk of diffuse agricultural pollution occurring. The waste producer or their contractor may carry out some, or all, of this work for farmers. Anyone wishing to apply industrial wastes to agricultural land must demonstrate in advance, and to SEPA’s satisfaction, that such an application will result in benefit to agricultural or ecological improvement. Note that the statutory controls on the application of sewage sludge to agricultural land must be complied with to be eligible for the Single Farm Payment.

Why are soil particles important?

2.11 Soil particles are also important because they can carry more serious pollutants. For example, some pesticides bind firmly onto soil particles and are therefore liable to contaminate watercourses when soil is lost from fields. Similarly, mud on farmyards and roads may carry oily residues. Phosphorus can be lost from farmland to water and can cause pollution. In excess, certain trace elements transported with the soil can also damage the aquatic environment. It should also be remembered that erosion very often involves the loss of the most fertile soil from a field.

Is soil a nonrenewable resource?

Soil particles. 2.10 Soil is effectively a non-renewable resource due to the time it takes to be formed. It should therefore be protected from damage or loss in order to sustain agricultural production, as well as for the life it supports in itself. In addition, soil and water quality are very closely linked.

Is the water quality in Scotland good?

2.3 Water quality in Scotland is generally good , and adherence to good agricultural practice is on the increase. Nevertheless, there are areas of concern. SEPA considers that diffuse agricultural pollution is now the most significant cause of poor river quality in certain parts of Scotland and that it will continue to be unless appropriate action is taken at individual farm and catchment level to turn the situation around.

Why is maintaining a high quality environment important in Scotland?

2.2 Maintaining a high quality environment in Scotland is essential for marketing high quality agricultural products. This link is one of Scotland’s strengths and should be at the heart of every successful farming business.

How can landowners prevent runoff?

It can also contaminate groundwater. Landowners can prevent runoff by using best practices that keep soil and other pollution out of streams and rivers.

How to keep livestock away from water?

Plant native trees and shrubs, keep livestock away from water’s edges, and leave grass or native buffers between tilled fields and streams. Leave stubble on tilled fields through the winter, cover manure piles, and plant a grass or native buffer between agriculture activities and streams.

What happens when landowners modify stream channels?

When landowners modify stream channels by ditching, dredging, or allowing animals to trample streamside vegetation, soil erodes and water temperature increases.

What is the water that carries manure, polluted sediment, bacteria, and chemicals?

Rainwater, snowmelt, and irrigation runoff carries manure, polluted sediment, bacteria, and chemicals into water.

How does land use affect water quality?

How does agricultural land-use affect water quality? 1 Rainwater, snowmelt, and irrigation runoff carries manure, polluted sediment, bacteria, and chemicals into water. 2 Leaky manure lagoons, over-application of nitrates, nutrients, and chemicals from manure pollutes groundwater. 3 When landowners modify stream channels by ditching, dredging, or allowing animals to trample streamside vegetation, soil erodes and water temperature increases.

Is there a one size fits all approach to improving operations and protecting clean water?

We understand that there is no one-size-fits-all approach to improving operations and protecting clean water. 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 can we reduce agricultural runoff?

One potential way to reduce the amount of agricultural runoff is by collecting and removing the contaminants in the runoff before it can enter the watershed. The advantage of this solution is that farmers do not need to change their growing practices or chemical usage.

How to reduce runoff from a field?

Another method to reduce agricultural runoff is to change the way crops are grown. One way to reduce runoff without changing the layout or profitability of the fields is to avoid tilling the field before planting. This increases the amount of nutrients in the field to begin with, and helps reduce soil erosion. Both of these reduce the amount of runoff coming from a field. The downside of this is that it increases the number of weeds in a field and requires stronger planting equipment than if a field was tilled before planting.

What is a simple but effective filter?

A simple but effective filter is a plastic tank filled with sand, rocks, topsoil, and wood chips. The simple design means that it is both low maintenance and low cost. Using this design, a research team achieved an 80% reduction in Nitrogen in the runoff, along with reductions in Phosphorus deposits and other contaminants.

Why is there a 6 point plan for farmers?

Farmers across the country are being encouraged to follow a 6-point plan in order to reduce the risk of polluting waterways by Inland Fisheries Ireland. An appeal has been made to farmers to remain vigilant during the summer months when harvesting silage and spreading slurry, in order to avoid water pollution and the loss of nutrients to water.

Is silage effluent a problem?

Silage operations are ongoing all summer and silage effluent has the potential to cause devastating pollution in streams and rivers, it added.
