> 1)Megnesium Sulphate: Magnesium is the central core of the chlorophyll molecule in plant tissue. If magnesium is deficient, the shortage of chlorophyll results in poor and stunted plant growth. Magnesium also helps to activate specific enzyme systems. Desert energy magnesium sulphate is a Water soluble, straight fertilizer, with sulphur and magnesium. It is free from chlorine, sodium and heavy metals. Appeared as White crystals. Dissolve quickly in water without any residues. Excellent source of Mg, useful in high saline irrigation water with very low EC value and to correct soil pH. > 2) Ammonium Sulphate:It is completely water soluble fertilizer with combination of Nitrogen (N) and Sulphur (S). It is free from chlorine, sodium and heavy metals and having crystals appearance. Sulphur is vital for the production of amino acids that form protein and is necessary for chlorophyll formation and photosynthesis. Nitrogen is also vital for these plant cell metabolic processes and deficiency results in poor growth and chlorotic discoloration. Sulphate of Ammonia is a quick acting, nitrogen fertilizer which encourages leafy growth. It is especially beneficial for crops such as brassicas, lettuce, spinach, rhubarb, leeks and onions. > 3)potassium sulphate: (SOP) is added to improve the yield and quality of fruits and plants growing in soils that are lacking an adequate supply of this essential nutrients. SOP is free of heavy metals and free flowing fine crystalline powder which dissolves quickly in water without any residues. Rich source of sulphur which is very important for protein and fatty acid building. The low pH of SOP contributes to a slight acidification of the zone surrounding roots, enhancing the availability of both macro and micro-nutrients present in the soil. SOP is a perfect source of a potassium in open field and hydroponic system.
