Minerals for plant growth

In order to grow healthily, plants need light, carbon dioxide, oxygen, water and up to 16 minerals.
As plants get water and minerals from the soil, it is important that the soil has the right nutrients for the plant
to grow. Different species of plants need different amounts and types of minerals to grow properly.
However, the main nutrients plants need are: nitrogen, phosphorous, potassium and magnesium.

Nitrogen (taken in as water soluble nitrates)

  • needed to make amino acids and proteins
  • needed for cell growth

Lack = short plant + older leaves
Lack = turn yellow

Phosphorous (taken in as water soluble phosphates)

  • needed to make DNA and cell membranes
  • needed for respiration and growth

Lack = poor roots + older leaves
Lack = turn purple
