Fertiliser - GCSE Biology Definition

Fertiliser is a substance that is added to soil to help plants grow better. It contains important nutrients like nitrogen, phosphorus, and potassium, which plants need to thrive. These nutrients can be natural, coming from animal manure or compost, or they can be made artificially in factories. Fertilisers are used in farming and gardening to improve the health and growth of crops and plants. However, using too much fertiliser can harm the environment by causing pollution, so it’s important to use the right amount.
