Agricultural fertiliser, i.e. chemical fertiliser, or chemical fertiliser for short, is a fertiliser containing one or several nutrients needed for crop growth, made by chemical and/or physical methods. Common chemical fertilisers include nitrogen fertiliser, phosphate fertiliser, potash fertiliser, compound fertiliser and micronutrient fertiliser. Fertiliser plays a vital role in agricultural production, as it can increase crop yields, improve soil fertility, promote plant growth, regulate the crop growth cycle, and even have the effect of controlling pests and diseases.
