Minerals for Healthy Growth.

Plants need various mineral salts and carbohydrates made by photosynthesis so they can growth properly. They get mineral ions from soil by absorbing them through their roots, There are two minerals in particular:

1) NITRATES

Nitrates are needed for making amino acids, which are used to make proteins.

2) MAGNESIUM

Magnesium is needed to make chlorophyll, which in turn is needed for photosynthesis. Other minerals needed by plants include potassium and phosphates, which make things like DNA and cell membranes, also helping enzymes involved in photosynthesis and respiration to work properly.

Lack of These Nutrients Causes Deficiency Symptoms.
