Sulphur for Autumn

Soil analyses from Lancrop labs during spring of 2011 showed that 88% of soils tested were low in sulphur for all crops.
In 2010 42% of wheat crops received an average application of 22kg S/ha, and 64% of OSR crops were treated receiving an average of 34kg S/ha.
Only 6% of grass fields received sulphur fertiliser and the average application was 12kg/ha.
Increasing costs of nitrogen emphasize the need to use it efficiently and Sulphur is essential for the plant to utilise N correctly.
Deficiency results in poor winter hardiness of crops.
Sulphur deficiency decreases photosynthesis and inhibits protein synthesis this results in smaller plant size. Autumn applied elemental S will feed the crop as it establishes and allow efficient use of nitrogen which was not utilised by the previous cropping.

Scientists at SAC and in Germany found lower concentrations of S containing metabolic compounds in S deficient plants with reduced vigour and increased susceptibility to disease. Recent work at the Institute of Plant Nutrition in Germany has shown that a constantly high available plant S reserve in the soil might be required to satisfy the enhanced demand for S for plant defence during infection by fungal pathogens.
German work has also shown that oilseed rape can take up more than 100kg nitrogen/ha reducing leaching and pollution but creating a demand for S to allow protein formation.
Minimum S level in leaf for high yielding oilseed rape crops is 0.65% S.
Most crops contain as much S as P in the plant.
Sulphur Supreme is the most efficient way of providing the plant with sulphur as the majority of particles within the pastille are < 150 microns and will be broken down during the life of the crop.
Available as 2-4mm pastilles.
