Description
NPK compound fertiliser is a type of fertilizer that contains nitrogen (\(N\)), phosphorus (\(P\)), and potassium (\(K\)). The letters NPK come from the chemical symbols for these elements. NPK fertilizers are used to help plants grow by providing essential nutrients.
Nutrients
NPK fertilizers provide nitrogen for leaf growth, phosphorus for root, flower, bud, and fruit growth, and potassium for overall plant health and disease resistance.
Ratios
NPK fertilizers have different ratios of nitrogen, phosphorus, and potassium, such as 10-10-10 or 16-20-18. The ratio indicates the percentage of each nutrient in the fertilizer.
Form
NPK fertilizers can be solid, such as powder or granules, or liquid.
Application
NPK fertilizers can be spread by hand or machine to ensure even distribution of nutrients.
Benefits
NPK fertilizers are designed to maximize crop yield and quality.
They can be used on a wide variety of crops, from small plots to large fields.
Other nutrients
Some NPK fertilizers also contain additional nutrients, such as boron, iron, manganese, zinc, sodium, and selenium.
Complex compound formulations may contain a broader range of nutrients.
