Types of agrochemical
- Fertilisers are concentrated forms of plant nutrients used to enrich soils and enhance crop growth and yields.
- Many fertilisers are ‘NPK’ – they include the key elements of Nitrogen (N), Phosphorous (P) and Potassium (K) which are essential for plant growth.
- Can be both organic (made from living material like animal manure) or synthetic (manufactured chemically).
- Plant protection products (pesticides)
- Chemicals used in animal husbandry
- Antibiotics and pesticides for the control of livestock diseases and parasites.
- Hormones and other animal-growth regulators to regulate animal growth and development.
- Soil conditioners
- Chemicals or organic matter (e.g peat) that alter soil properties including water holding capacity and aeration.
- Liming and Acidifying agents
- Neutralize soils that are too acidic or alkaline to optimize the pH for growing conditions.
- Acidic soils are a particular problem in agriculture and can be caused by factors such as acidic rain and high inputs of nitrogen fertiliser.
- Calcium containing compounds (liming agent) are often used to rectify acidic soils and sulphur compounds (acidifying agents) are often used to rectify alkaline soils.
