Magnesium Based Fertilizers

Magnesium (Mg) is required by all plants. Plants obtain this magnesium from the soil under ideal growing circumstances. However, leaching, particularly in sandy soils, as well as environmental factors including moisture, temperature, and an acidic root environment might limit the availability of magnesium. Magnesium uptake by plants can also be hampered by an imbalance of nutrients in the soil, such as high levels of potassium, calcium, or ammonia.

The Role of Magnesium in Crops

Magnesium is necessary for photosynthesis, the process through which plants use the sun’s energy to grow and produce. Chlorophyll, the green pigment found in plants, is the product of photosynthesis. Each chlorophyll molecule contains 6.7% magnesium; thus, Mg serves as the molecule’s core element.

Magnesium is also essential for the activation of enzymes necessary for respiration, photosynthesis, and the production of nucleic acids. It acts as a transporter of phosphate molecules throughout the plant, assisting in phosphate metabolism. Magnesium helps move carbohydrates (such as sugars and starches) around the body, boosts the creation of fats and oils, and is important for cell division and growth.

 

 

Symptoms of Magnesium Deficiency

Older leaves of magnesium-deficient plants have interveinal chlorosis, which consists of dark green veins with yellow spaces in between. The edges of these yellowed or chlorotic leaves curl, and spots of dead tissue appear on them. The lower or older leaves are always the first to be impacted since magnesium is mobile in plants.
