Nitrogen is a vital element for plants because it is a major component of amino acids, which are the building blocks of proteins. Proteins are essential for various physiological functions in plants, including enzyme activity, growth, and structural development. Nitrogen is absorbed by plants in the form of nitrates and ammonium ions from the soil, and it is incorporated into proteins, nucleic acids, and other cellular components. Magnesium, on the other hand, is an essential component of the chlorophyll molecule, the pigment responsible for capturing light energy during photosynthesis. Magnesium acts as a central atom in the chlorophyll molecule, which enables the absorption of light in the blue and red regions of the light spectrum. Without magnesium, plants cannot produce chlorophyll properly, which hinders the process of photosynthesis and reduces the plant’s ability to generate energy.
