Product Technical Sheet - Foliar Nutrition OMEX Sulphomex® An inorganic liquid formulation containing nitrogen and sulphur. Sulphomex is suitable for foliar application and is formulated for rapid plant uptake. Crops Most agricultural crops including cereals, oilseed rape, grassland, sugar beet and potatoes. Use To correct nutrient deficiency. Pack Sizes 20, 1000 litres Analysis w/w w/v Function of Sulphur Sulphur is a key element for plant growth and development being a key constituent of enzymes and amino acids involved in photosynthesis and protein formation. The amino acids cysteine and methionine, which contain sulphur, are particularly important in the bread making process. Sulphur is also a key constituent in oilseed crops. Sulphomex is a true foliar nutrient supplying sulphur through the leaf at times of maximum requirement. Sulphur can only be taken into the plant as SO2 or SO4 and Sulphomex is an ideal formulation ensuring maximum uptake of nutrient. Sulphur Deficiency Sulphur has been traditionally supplied by atmospheric deposition, animal slurries and an impurity of mineral fertilisers. The implementation of the Clean Air Act, the move to arable farming and changes in fertiliser usage have resulted in lower applications of sulphur to many crops throughout the UK. Sulphur deficiencies have been observed in a number of crops, notably oilseed rape, 2nd and 3rd cut silage, and vegetable brassicas. The benefits of sulphur application have been seen on the crops above and on cereals and sugar beet. The mobility of sulphur in plants is poor, thus yellowing is seen on the newest growth rather than on older leaves. This distinguishes sulphur deficiency from nitrogen deficiency. Yield benefits of sulphur application have been seen even when sulphur deficiencies have not been seen in the crop.
