Know Your Nutrients: Magnesium


Magnesium (Mg) is a secondary nutrient and the only mineral component of chlorophyll, the green pigment in plants. Without magnesium, there would be no chlorophyll and without chlorophyll, there would be no photosynthesis.

Besides being integral to the process of capturing and converting sunlight to energy, magnesium also helps a plant efficiently use carbon dioxide (C02).

Know Your Nutrients: Calcium


Required by all plants to grow and thrive, calcium (Ca) plays a big part in plant development and fruit quality. Although it’s considered a secondary nutrient, a plant’s need for calcium can be as high as its needs for nitrogen and potassium

Calcium is essential for the proper functioning of growing points, particularly root tips and nodules. It aids in cell division, forms compounds which strengthen cell walls, supports the function of cell membranes, and helps control enzyme activity and the metabolism of starch.

Know Your Nutrients: Sulfur


Sulfur (S) is a secondary nutrient, but it can be just as important as the primary (macro) nutrients. In fact, a plant’s sulfur requirements are similar to its needs for phosphorus, which is why some people call it “the fourth macronutrient.”

Sulfur is essential for plant growth, aiding in enzyme and vitamin activities, chlorophyll formation and nitrogen stabilization. It is an integral part of several amino acids which are essential for protein production and is necessary for nodule formation in legumes.

Know Your Nutrients: Potassium


Potassium (K) is a primary (macro) nutrient that functions as a regulator within a plant’s cells, improving the overall quality and resilience of the crop. 

Potassium aids in photosynthesis and the functioning of chlorophyll; helps form and translocate starches, sugars and fats; and supports enzyme actions and the formation of proteins.

Know Your Nutrients: Phosphorus


Phosphorus (P) is a primary (macro) nutrient needed for plant development and growth throughout the entire life cycle – from seedling to maturity.

A macronutrient, phosphorus is necessary for cell formation and division, and plays a key role in photosynthesis and energy transfer in the plant. Phosphorus also stimulates root development and improves plant strength, seed production and overall quality.
