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 is it important to engage in watershed efforts?

Engaging in Watershed Efforts: The collaboration of a wide range of people, stakeholders and organizations across an entire watershed is vital to reducing nutrient pollution to our water and air. Farmers can play an important leadership role in these efforts when they get involved and engage with their State governments, farm organizations, conservation groups, educational institutions, non-profit organizations, and community groups.

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 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.

How to prevent agricultural pollution?

5. Have a Manure Management Plan. Along with having an accurate nutrient management technique, having a manure management plan is important to preventing agricultural pollution. Using manure is a common practice that can help replace fertilizer application. The long-term benefits include an increase in soil productivity in the long run.

How to prevent pollution on farm?

There are several ways to prevent accidents caused by pollution on the farm, especially regarding nutrient runoff. 1. Add Conservation Buffers to Catch Runoff. Landscaping isn’t just for beauty anymore. Planting trees, shrubs and grasses along the edges of your fields to add as a conservation buffer can help prevent any runoff.

How does tillage help soil?

Using a more conservative tillage schedule can help reduce erosion, runoff and soil compaction, which helps reduce the chances of nutrients reaching waterways or non-owned land. Minimal tilling is also beneficial in improving soil quality, reducing soil sheet erosion and reducing crop establishment time and energy use.

How to keep livestock out of streams?

Installing fences along any streams, rivers or lakes to keep livestock out of them can help restore the stream banks. It also prevents the livestock from dragging in nutrients or other agricultural pollutants into the water. Make sure the livestock have access to other sources of fresh water instead.

How to improve nutrient management practices?

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.

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.

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 problems caused by leached nutrients?

2.19 If leached in excessive amounts, nutrients such as nitrogen (N) and phosphorus (P) can cause severe problems for rivers, lochs, estuaries and coastal waters by, for instance, contributing to the development of toxic algal blooms or foul smelling mats of algae on our coastline. Nutrients can be lost from manures and slurries as well as from other organic wastes spread on land, and significant losses can also be associated with fertilisers and soil. Advice must be tailored to the particular farm and catchment area in order to prevent such losses and reduce the risk of pollution.

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.
