Iron sulphate is used to green & toughen up grass as well as suppress the growth of moss. Apply by knapsack or boom sprayer to ensure there is good coverage of the moss. Use 500L of water per hectare to help improve coverage of thicker swards of grass. This particular Iron Sulphate has a built in acidifier system which helps to slow the oxidising effect which in turn blocks nozzles & sprayers. This is a high-quality iron formulation used by many professionals.
Iron sulphate can be used all year round including during colder spells of weather, where it will help strengthen the plant against frost and disease. Iron is absorbed by the leaf giving rapid results and has been known to blacken moss within hours. This product is fully dissolvable in water although good agitation is advised in order to avoid blocked nozzles. It is ideal for treating large areas such as horse paddocks & amenity areas.
