Nutrient Function

Nitrogen Icon
Nitrogen is the main plant protein component and is needed in large quantities for healthy plant growth. Nitrogen deficiency can lead to root disease, reduced photosynthesis, stunted plants and reduced crop yield, while sufficient nitrogen can increase tolerance to early-season soil diseases.
Magnesium Icon
Magnesium is critical for chlorophyll production as it serves as the backbone of the chlorophyll molecule. Magnesium also stimulates enzyme reactions in the plant that help with phosphorus transport. Elevated calcium, potassium and ammonium levels in the soil will reduce magnesium availability for the plant.
