Potassium is an essential plant nutrient that is required in large amounts for proper growth and the reproduction of plants. Potassium is commonly considered as the ‘quality nutrient’. It affects the shape, size, colour, taste of the plant and other measurements attributed for a healthy crop production.
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 many plant functions. One of the magnesium’s well-known roles is in the photosynthesis process, as it is a building block of Chlorophyll, which makes leaves appear green. Some amino acids contain magnesium as well; 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.
