Magni Top




Bags kg. 25

Magnesium is a fundamental chlorophyll element and is an essential nutrient for crops; it plays an important role in the synthesis of carbohydrates, proteins and fats and is involved in catalytic reactions of enzymatic systems and in vitamin formation. The first symptoms of Magnesium shortage are shown as yellow patches along either side of the leaf midrib and occasionally close to the tip. In other cases the whole leaf yellows or falls. Serious shortages are seen on several crops like grapes, citrus, top-fruit and vegetables. Decreasing organic fertilizer application and intensifying cropping cycles often induces magnesium deficiency compromising yields. In grapes, for example, magnesium deficiency causes the rachis to dry up leading to withering of the entire bunch; in citrus fruit size decreases substantially together with vitamin C content causing an early drop. All these problems are easily solved using MAGNI TOP. Because it is based on Magnesium Nitrate (a more soluble molecule than the sulphate or chloride) it is immediately and completely absorbed by the crop. The nitrogen supplied by the nitrate ion also helps the plant to recover more rapidly from the symptoms of chlorosis.
