Application Of Manganese Sulphate

Uses
Manganese, supplied as manganese sulphate, is used to alleviate Mn deficiencies which are most common in Northland & on the West Coast of the South Island & in peat soils. Manganese sulphate is also applied to soils or as a foliar application for cereal production where a history of Mn deficiency exists. If applied as a foliar, ensure Manganese Sulphate Soluble is requested.

application :
Typical soil application rates for manganese sulphate are 15kg/ha, however in some highly deficient situations rates of up to 25kg/ha may be required. Can be added to most fertilisers. For foliar applications to cereal crops, apply Manganese Sulphate Soluble at 8-10 kg/ha, dissolved in 200 litres of water. Include a wetting agent (Agriwett 77) for improved spread on foliage. For crops with visual Mn deficiencies, it is advisable to apply 2 applications, 3 weeks apart.

other use :

Used as a porcelain glaze, as a fertilizer additive and as a catalyst. It is added to soils to promote plant growth, especially of citrus crops. It is a good reducing agent for manufacturing paints, varnish driers. It is used in textile dyes, fungicides, medicines and ceramics. In foods, it is used as a nutrient and dietary supplement. It is also used in ore flotation, as a catalyst in viscose pro- cess and in synthetic manganese dioxide. In veterinary medicine, it is used as a nutritional factor and in the prevention of perosis in poultry.
