KayNitro Sulphur

KayNitro Sulphur 25.0.13 + 7 SO3 is the ideal mid and late season fertiliser for grass silage.

Where crops are grown on soils high in phosphate, KayNitro provides balance with large offtakes of potash. Flexible grades are available for forage maize and arable crops where high potash/low phosphate applications are essential. Nitrogen, phosphorous, potassium and sulphur all play essential roles in healthy crop growth.

The benefits of using KayNitro Sulphur

  • Potash applied during the growing season reduces autumn workload
  • By applying sulphur in sulphate form, crops are able to readily absorb the nutrient quickly and efficiently
  • According to government research, ammonium nitrate is the most efficient nitrogen source and the ‘best option for the environment and farming’
  • As a true granular compound, Heartland Sulphur guarantees an even application of all nutrients across the whole spreader bout width, optimising nutrient use efficiency and crop response
  • Potash-sufficient soil optimises the benefits of nitrogen
  • Zero phosphate content makes this compound suitable to fit a range of circumstances where high soil reserves or use of organic matters of biosolids/sewage sludge cake means no fertiliser phosphate is required.

Application Information

The exact recommendation depends on your soil analysis and nutrient management plan. Consult with your Frontier/SOYL agronomist for detailed advice. Find out more about our agronomy services by visiting Soil Life.

Grassland Use as a general grassland fertiliser on soils with high phosphate index. For second and subsequent silage crops apply 300-350kg/ha immediately after previous crop is removed. For grazing, apply 160-200kg/ha NK Sulphur on a monthly basis following turnout. With sulphur, trials have shown increases in DM yield of 25% can be achieved on light and medium soils, alongside increases of 4% in protein and 5% in sugar contents to improve grass quality and palatability.
Maize Use KayNitro Sulphur to supplement organic manures on high phosphorous index soils as a seedbed fertiliser using 200-300kg/ha at crop emergence.
Arable Use as a spring top dressing where additional potash is required to maintain or build soil potash levels. Apply at a rate that delivers the required nitrogen.
Grass silage The optimum sulphur application rate is 40kg SO3/ha per cut.
Cereals The optimum sulphur application rate is 50 kg SO3/ha.
Oilseed rape The optimum sulphur rate is 112 kg SO3/ha. If using KayNitro Sulphur then an early application of DoubleTop can be used to supply more sulphur.
