As well as light energy, water and carbon dioxide, plants need minerals like nitrates and magnesium to grow or they will die.

The plant need carbohydrates for energy, storage and even cell walls, but a plant can't survive without proteins either. It needs proteins to make enzymes and make up a large part of the cytoplasm and the membranes.  

They need nitrates from the soil to make proteins (combined with sugar to make amino acids which then build up into proteins). The nitrates are dissolved in the water and get taken up through the roots of the plant. if the plant is deficient in nitrates, it…
