What You'll Learn
Using organic and mineral fertilisers
Organic fertilisers are made from natural materials such as animal manure, compost, and plant residues. They release nutrients slowly over time, which helps to improve soil structure and fertility. Mineral fertilisers, on the other hand, are made from inorganic materials such as rock phosphate and greensand. They provide a quick boost of nutrients to plants and are often used to correct specific nutrient deficiencies in the soil.
One of the main benefits of using organic and mineral fertilisers is that they do not contribute to the release of excess nitrogen into the atmosphere. Excess nitrogen from synthetic fertilisers can have a detrimental impact on both the environment and human health. By using organic and mineral fertilisers, farmers can help to reduce air pollution and mitigate the negative effects of chemical fertilisers.
Another advantage of organic and mineral fertilisers is that they can be used in conjunction with sustainable agricultural practices such as crop rotation and organic farming. Crop rotation helps to improve soil health and reduce the need for fertilisers, while organic farming emphasises the use of natural processes and materials to produce crops. By combining organic and mineral fertilisers with these practices, farmers can further reduce their environmental impact and promote a more sustainable approach to agriculture.
In addition to the environmental benefits, using organic and mineral fertilisers can also have economic advantages for farmers. By reducing their reliance on synthetic fertilisers, farmers can lower their input costs and increase their long-term profitability. Additionally, by improving soil health and fertility, organic and mineral fertilisers can lead to increased crop yields and better-quality produce, which can command higher prices in the market.

Using manure instead of fertiliser
Fertilisers contribute to air pollution, especially when excess nitrogen is released into the atmosphere. To stop fertiliser pollution, you can use manure instead of fertiliser. Manure is a common practice that can help replace fertiliser application and increase soil productivity in the long run. To do this, you should have a manure management plan that includes 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.
You can also prevent fertiliser pollution by implementing the use of organic and mineral fertilisers, which provide nutrients to plants and improve agricultural crops in a more balanced way for the soil, without emitting synthetic derivatives that pollute soil, water and air. This means encouraging crops free of fertiliser residues such as nitrates through sustainable agricultural practices such as crop rotation and organic farming.
Another way to prevent fertiliser pollution is to improve your nutrient management techniques. This means ensuring you are applying the fertiliser in the right amount, at the right time of the year, using the correct method, and in the right spot. You can also add a conservation buffer by planting trees, shrubs and grasses along the edges of your fields to help prevent any runoff, especially if your field borders a body of water. These buffers will help absorb nutrients that may run off or can help filter nutrients before they reach the water.

Reducing nutrient runoff
Another way to reduce nutrient runoff is to ensure you are applying the fertiliser in the right amount, at the right time of the year, using the correct method and in the right spot. This can be improved by having an accurate nutrient management technique, which can be part of a manure management plan. Manure can help replace fertiliser application and increase soil productivity in the long run.
You can also prevent nutrient runoff by planting trees, shrubs and grasses along the edges of fields to act as a conservation buffer. These buffers will help absorb nutrients that may run off or can help filter nutrients before they reach the water.
In addition, you can reduce personal nutrient pollution by keeping leaves and grass clippings on the lawn, rather than blowing them into the street or down the drain. This keeps those nutrients in your yard as a natural fertiliser.

Accurate measurements of agricultural emissions
Firstly, managing fertilizer usage is crucial. This involves monitoring the amount and type of fertilizer applied, as well as the timing and method of application. By using fertilizers with at least 65% slow-release nitrogen, for example, farmers can reduce the risk of runoff and leaching, which are significant sources of nutrient pollution in waterways.
Secondly, following local rules and best practices is important for reducing emissions and protecting the environment. For instance, in Miami-Dade County, the Florida-Friendly fertilizer ordinance includes rules such as skipping fertilizers during the rainy season (May 15 – Oct. 31) and applying fertilizers at least 20 feet away from bodies of water and storm drains. Adhering to such guidelines can significantly reduce nitrogen and phosphorus levels in waterways, enhancing the health of aquatic ecosystems.
Additionally, spreading awareness and educating the community about fertilizer pollution can lead to collective action and a more sustainable approach to fertilizer usage. Homeowners, landscapers, and other professionals can play a crucial role in preventing environmental pollution by staying updated on best management practices and regulations. This includes recognizing and reporting pollution incidents, as well as adopting sustainable practices in their own communities.
Furthermore, implementing a rotational grazing system can facilitate composting and reduce nutrient impacts. By rotating grazing areas, farmers can more effectively manage manure and organic waste, reducing emissions and improving soil health. This approach also promotes even fertilizer distribution, as grazing animals naturally distribute nutrients across the land.
By combining accurate measurements of agricultural emissions with sustainable practices, communities can effectively reduce fertilizer pollution and safeguard their local environments for future generations. These measurements provide a scientific basis for decision-making, ensuring that actions taken are effective and targeted, ultimately leading to a more sustainable and harmonious relationship with nature.

Sustainable agricultural practices
One way to reduce fertiliser pollution is to use organic and mineral fertilisers instead of synthetic ones. These provide nutrients to plants and improve agricultural crops in a more balanced way for the soil, without emitting synthetic derivatives that pollute soil, water and air. Sustainable agricultural practices such as crop rotation and organic farming can also help to encourage crops free of fertiliser residues such as nitrates.
Another way to reduce fertiliser pollution is to improve nutrient management techniques. This includes applying the right amount of fertiliser, at the right time of year, using the correct method and in the right spot. Having a manure management plan can also help to prevent agricultural pollution. Manure can help to replace fertiliser application and increase soil productivity in the long run. A plan could include soil sampling and assessment, nutrient management techniques, and investing in manure storage structures to avoid spills and water contamination.
Landscaping can also help to prevent fertiliser pollution, especially nutrient runoff. Planting trees, shrubs and grasses along the edges of fields can act as a conservation buffer, helping to absorb nutrients that may run off or filtering them before they reach the water.
