Physical Characteristics

Granusol Managanese contains 36% Manganese by weight.

Using Soil Applied Granusol Manganese: The Benefits Over Spraying

• One application of Granusol® in the Spring Fertiliser will give as much elemental manganese as three heavy or six light sprays of conventional Manganese Sulphate. One dose of Granusol® applied at 22Kgs/ha provides 8 Kgs/Ha [7lbs/ac] of Elemental Manganese incorporated into the soil.
• Manganese deficiency is most critical at the early stages of growth when there is not much leaf cover for a spray to be effective so a solid fertiliser incopororated into the seedbed is effective & persists. Up to 90% of the Manganese in a Manganese Sulphate spray can be lost when spraying young plants owing to inadequate leaf cover.
• Any Manganese Sulphate spray coming in contact with the soil becomes unavailable at pH's above 7.4. Granusol® is buffered with its acidic sugar to ensure availability at higher pH's. American University and Federal Agency Trial Work has shown that while Manganese Sulphate soon becomes locked up, Granusol Manganese remains highly available for the rest of the growing season.
• The Granusol Manganese is available to the plant in the root area as it is growing
• Soil nutrition gives a more natural and even growth habit. Upon application, a flush of Manganese is released to the plant. As the Granusol® powder breaks down further, more Manganese is then slowly released to the soil.
• Using Granusol®will not scorch the crop
• On crops that are sprayed frequently with Manganese Sulphate alone or with tank mixes that include wetting agents, the waxy leaf coating is never re-built. The sulphate in the Manganese Sulphate can then cause mild crop scorch setting back a crop already under stress.
• There is often a chronic [ie unnoticed] Manganese deficiency that affects the plant without being outwardly visible. Granusol® Manganese can be incorporated in the spring fertiliser as an insurance against Manganese deficiency on soils where spraying is not normally required.
• Manganese Spraying still can be delayed until later in the growing season
• If spraying is left until later in the season, crops like peas and root crops suffer less compaction. Fewer passes over the land results in savings on machinery and labour costs and frees up management time. This is especially so with crops grown on hired land away from the main farm.
• A long term treatment programme can build up soil Manganese levels
• The American experience has shown that if Micronutrients are applied over a period of years, soils that were seriously deficient before, can build up their manganese reserves so as to offer better natural plant nutrition.
