Manutec Sulphate of Ammonia provided by Sir Walter is the ammonium sulphate chemical that is used to lower the alkaline levels of soil in gardens and lawns. Therefore, sulphate of ammonia from Manutec is useful to reduce the alkaline level of soil if it is higher than the level of 7. In this case, 6.5 is the optimal alkaline level of the soil.
Manutec Sulphate of Ammonia provided by Sir Walter is available in the form of odourless white or pale crystals. This sulphate content is soluble in water, and generally the product is not harmful when exposed to any body part. But it may cause some irritation in the eyes and skin in case it comes in direct contact. Therefore, it is recommended to use gloves or dust masks, while handling ammonium sulphate. The sulphate has a melting point of up to 280 degrees. But it is not soluble in organic solvents.
