Fertilizer - Simple English Wikipedia

# Fertilizer

### From Wikipedia, a free encyclopedia written in simple English for easy reading.

A fertilizer is a chemical that helps plants to grow. It is used to replace the mineral salts taken by plants or removed by rain.

Manure was the first fertilizer.

Common fertilizers:

- Ammonia
- Manure (Animal waste)
- Compost
- Urea

The important things in fertilizer are:

- Nitrogen (N)
- Phosphorus (P)
- Potash (K)

When you buy fertilizer, the percentage of N, P, and K in it is written on the bag or box, like this:

  9-23-30

That means 9% N, 23% P, and 30% K.

Leafy plants need lots of N. Flowering plants need lots of P and K.

A soil test can tell you how much N, P, and K you need.
