Potassium is an essential plant nutrient and is required in large amounts for proper growth and reproduction of plants. Potassium is commonly considered as the “quality nutrient.” It affects the plant shape, size, color, taste and other measurements attributed to healthy produce.
Potassium plays a major role in the regulation of water in plants. Both uptake of water through plant roots and its loss through the stomata are affected by potassium. Protein and starch synthesis in plants require potassium as well. Potassium is essential at almost every step of the protein synthesis. In starch synthesis, the enzyme responsible for the process is activated by potassium.
Magnesium is an essential plant nutrient. It has a wide range of roles in many plant functions. One of the magnesium’s well-known roles is in the photosynthesis process, as it is a building block of the Chlorophyll, which makes leaves appear green. Also some amino acids contain magnesium; a deficiency will result in an insufficient supply of true proteins requiring those amino acids. The missing proteins reduce the quality of produce for both animal and human consumption.
