ResourceChallenging Plants: Fertilisers
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 ...
