NPK
Plants need three main mineral ions for growth: nitrates, phosphates and potassium. They get theses mineral ions from the soil. If there aren't enough, plants suffer deficiency symptoms.
1 of 5
Nitrates
Nitrates contain nitrogen for making amino acids and proteins. These are needed for cell growth. If a plant can't get enough nitrates it will be stunted and will have yellow older leaves.
2 of 5
Phosphates
Phosphates contain phosphorus for making DNA and cell membranes and they're needed for respiration and growth. Plants without enough phosphate have poor root growth and purple older leaves.
3 of 5
Potassium
Potassium is needed to help the enzymes needed for photosynthesis and respiration. If there's not enough potassium in the soil, plants have poor flower and fruit growth and discoloured leaves.
4 of 5
Magnesium
Magnesium is needed in small amounts. It is used for making chlorophyll, needed for photosynthesis. Plants without enough magnesium have yellow leaves.
