Ca. S. H is an Egyptian company specializing in the manufacture of organic mineral fertilizers that aim to correct the damage to soil salinity levels caused by sewage dumping and a lack of irrigation. In Fayoum, 38% of agricultural land lacks sufficient supply of minerals for farming, and this figure is on the rise. In order to compensate for the lack of irrigation water and increase agricultural production rate, Ca. S.H provides a solution in the form of an organic mineral compound that is combined with fertilizers and can also be sprayed directly onto the plants. This solution increases the crop supply and, because it is also rich in antioxidants, the compound nurtures produce grown allowing farmers to reduce their use of phosphates, retain the natural benefits of their crop and maximize the harvest. Ca. S. H stands for calcium, sulphate, and potassium humic – the components of the soil enriching compound.
