SulphaGro46 contains large amounts of Sulphur (46% SO3) and Calcium (24% Ca) along with smaller quantities of trace elements including Iron, Sodium, Copper and Boron. The Sulphur is available and is an extremely cost-effective way of building up soil Sulphur levels.
Sulphur dioxide emission was once the major source of Sulphur for crop growth but pollution legislation has resulted in a dramatic decline.
Most of the country now receives less than 40 kg/ha of Sulphur (32 units/acre) with much of the north and Scotland receiving less than is removed annually in arable and grass crops.
SulphaGro46 is designed to correct and prevent Sulphur problems.
Why is Sulphur so important?
Sulphur is the fourth major nutrient effecting both yield and quality of crops. The crop demand for Sulphur is about equal to that for phosphate.
Soils in Britain do not contain a permanent reserve of Sulphur since surplus is removed by leaching in the winter and it is essential to replace Sulphur losses each year. This problem becomes more acute in high rainfall areas.
In many areas of Britain, cereals and oilseed rape are receiving inadequate levels of Sulphur resulting in lower yields and grain quality.
Second and third silage cuts can also be affected by low Sulphur levels. application of SulphurGro-46 can be used as a cost-effective way of correcting this deficiency.
A series of 32 field trials between 1985 and 1993 in the main grassland areas showed an average yield increase for Sulphur at second cut stage of 0.24 t dm/ha increasing to 0.71 t dm/ha on responsive sites.
What are the benefits of SulphaGro46?
SulphaGro46 is a unique soil improver. It helps to increase the permeability and friability of heavy clay soils by encouraging dispersed clay particles to coagulate. This not only helps in surface draining but also makes the soils easier to break down reducing diesels and machinery costs.
Crop and grass roots grow more strongly after application of Sulphagro46 due to easier penetration by plant roots. Yield benefits can be demonstrated on most crops.
In six field trials conducted by Levington Agriculture in 1986 in the main oilseed rape growing areas, results showed an average yield increase of 0.14t/ha when Sulphagro46 was applied.
