As a result, they add to the process of agricultural pollution by way of emissions.
How do farmers affect the environment?
Farmers often unknowingly cause harm to the environmental system. They should be taught that the excessive use of fertilizer and pesticides has a huge adverse impact on the whole ecosystem. Thus, by increasing the farmers’ knowledge and awareness, agricultural pollution can be mitigated to a certain degree. They must know: 1 Applying the right quantity of pesticides and fertilizers that are necessary to get a reasonable crop yield. 2 Using cover crops to prevent bare ground when the actual harvest is over, thus preventing soil erosion and loss of waterways. 3 Planting grasses, trees and fences along the edges of a field that lies on the borders of water bodies. They could act as buffers, and nutrient losses can be avoided by filtering out nutrients before reaching the groundwater. 4 Reduction in tillage of the fields in order to reduce runoffs, soil compaction and erosion. 5 Animal or cattle waste is a big cause of agricultural pollution. The management of these pollutants is crucial. 6 Several manure treatment processes need to follow, which aim to reduce the adverse impact of manure on the environmental system.
What causes soil to build up in areas such as rivers, streams, ditches and surrounding fields?
The resulting sedimentation causes the soil to build up in areas such as rivers, streams, ditches and surrounding fields. And so, the process of agricultural pollution prevents the natural movement of water, aquatic animals and nutrients to other fertile areas. 4. Livestock.
How does agriculture affect soil fertility?
Soil Pollution and Depletion of Soil Fertility. The agricultural pollution contaminates soil that leads to soil pollution and depletion of soil fertility by killing soil microorganisms.

What are the main sources of agricultural pollution?
Use of fertilizers and pesticides. Pesticides and fertilizers are one of the major sources of agricultural pollution. The purpose of these fertilizers and pesticides is to kill the local pests that damage the crops. When these pesticides are sprayed on crops, some of its chemicals get absorbed by soil, water and by the plants itself.
What are some agricultural activities that contribute to air pollution?
Some agricultural activities considered as sources of air pollution such as the burning of fossil fuels in tractors, emission of gases through livestock & fertilizers, emission of greenhouse gases from machinery used for farming purposes, etc.
How does agriculture affect the aquatic ecosystem?
Agricultural pollution affects aquatic life. Agricultural wastes also affect the aquatic ecosystem. When fertilizers and pesticides mix with water it converts into nitrate which minimizes the level of oxygen present in water. A low level of oxygen causes the death of innocent water animals.
What are the traces of heavy metals in soil?
Traces of heavy metal. The pesticides, fertilizers and industrial wastes sometimes contain some traces of heavy metals like cadmium, lead, arsenic, etc. These heavy metal traces get dissolved with soil, mix with water sources, sucks by the groundwater and sometimes are absorbed by the crops also.
What are the causes of water pollution?
Agricultural pollution is one of the main causes of water pollution. When the chemicals from different manure, pesticides, fertilizers are dissolved in water bodies (especially in groundwater), it ended up drinking polluted water.

How does agriculture affect the environment?
Effects of agricultural pollution. Since agricultural pollution is not a lone standing entity, its effects are carried over as water pollution and air pollution. It affects every aspect of the environment and every organism from the earthworm to humans. Some of the adverse effects are as follows:
How can agriculture reduce water pollution?
Prevention of Agricultural pollution 1 Prevention can never be a solo effort. The state governments, farmers’ organisations, collectives and cooperatives, educational institutions and conservation groups need to work together for regulating and reducing farming related water pollution. 2 Planning the application of fertilizer at the right time, in the right quantity with the correct methods can reduce the run off 3 Planting certain grasses and clovers that can absorb and recycle the additional nutrients and prevent soil erosion. Planting rows of trees and shrubs around fields and along the borders of the stream or lake also help in the same way. 4 Over tilling of the soil must be avoided to prevent soil erosion and soil compaction. 5 Managing the correct disposal of animal wastes and keeping farm animals away from water will reduce the nitrogen pollution of the water. 6 Composting, solid liquid separation, anaerobic digestion and lagoons are different ways of managing animal manure. Of these anaerobic digestion is the most effective. It involves the use of anaerobic bacteria and heat. The products of this process are nutrient rich liquid used as fertiliser and methane gas that can be burned to produce electricity and heat. Anaerobic digestion is a best method for controlling odour associated with manure management.
