Challenging Plants: Fertilisers

Description

Nutrients essential for plant growth are obtained naturally from soil or other growing media. However, supplies become depleted and fertilisers are needed to increase the availability of nutrients to plants. An understanding of chemical changes is used to making fertilisers, often designed to meet specific requirements such as particular nutrient deficiencies and methods of application (including rate of release).

An outline of the essential elements needed for healthy plant growth, indicating the quantities needed and hence the classification into primary, secondary and micro nutrients and describing organic and inorganic fertilisers. Quantities of nutrients in fertilisers might be used as a context for chemical calculations.
