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.
Oil Seed Rape
- 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.
