Fertilizer
A fertilizer is a chemical that helps plants to grow. It is used to replace the mineral salts taken by plants or removed/washed away by rain.
Common fertilizers:
The important things in fertilizer are:
- Nitrogen (N)
- Phosphorus (P)
- Potash (K)
When fertilizers are offered for sale, the percentage of N, P, and K must be written on the bags or boxes, but for historcal reasons, P is shown as %P2O5 and K is shown as %K2O.
E.g.:9-23-30 which means: 9% N, 23%P2O5 and 30%K2O.
In Australia the percent of elemental sulfur must also be shown. In the UK, the elemental composition (in percentages) may also be shown alongside the mandatory traditional system, provided the numbers are put inside square brackets.
Leafy plants need lots of N. Flowering plants need lots of P and K.
A soil test can tell how much N, P, and K is needed.
