KayNitro® Sulphur

1 of 1 products in this brand
KayNitro® Sulfur is a true granular compound ideal as a mid and late season fertilizer for grass silage. The product balances large offtakes of Potash where crops are grown on soils high in Phosphate. It is also a flexible grade for forage maize and arable crops where high Potash/low Phosphate applications are required to balance soil nutrient supply and where biosolids high in Phosphate are used in the fertilizer program. The addition of Sulfur enhances crop yield and quality in Sulfur-deficient situations.

Product Description
  • Ammonium Nitrate is the most efficient and predictable form of Nitrogen for UK growers.
  • Ammonium Sulfate offers a readily available source of Sulfur to the growing crop.
  • Water soluble Potash provides rapid uptake to support Nitrogen use efficiency and plant growth.
  • A True Granular Compound ensures even and accurate spread of all nutrients across the crop.
  • Bulk density typical range 900-1000 kg/m3, average 960 kg/m3.
  • The Carbon Footprint for KayNitro Sulfur is 4.0kg CO2 e per kg Nitrogen.
Features
  • Contains Ammonium Sulfate.
  • Contains Ammonium Nitrate.
  • Contains water soluble Potash.
  • A True Granular Compound.
  • Potash applied during the growing season.
  • Zero Phosphate content.
  • Manufactured at sites which are accredited to ISO 9001.
Benefits
  • A readily available form of Sulfur for rapid uptake – elemental Sulfur cannot be taken up directly by crops because plants only take up Sulfur in the Sulfate form.
  • AN is the most efficient Nitrogen source and the ‘Best Option for the Environment and Farming’ according to Government research.
  • ‘To optimize the benefits of N, it is essential to have sufficient exchangeable Potash in the soil.’ ref PDA March 2008.
  • Even application of all nutrients across the whole spreader bout width, which optimizes nutrient use efficiency and crop response.
  • Reduces autumn workload and potentially fertilizer application costs on arable crops. Potash is provided when the crop uses it most efficiently giving better yields and N uptake.
  • To fit a range of circumstances where high soil reserves or use of organic manures or biosolids/ sewage sludge cake means no fertilizer Phosphate is required. Reduces the risk of Phosphate loss to the environment.
  • Reliable product with consistent high quality, every year.

Applications & Uses

Applicable Crop
Applications

Grassland- Use as a general grassland fertilizer 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 Sulfur on a monthly basis following turnout. With Sulfur, 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 Sulfur to supplement organic manures on high P index soils as a seedbed fertilizer 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.

Notes: 

  • For grass silage, the optimum Sulfur application rate is 40 to 60 kg SO3/ha for 2 cuts and 60 to 80 kg SO3/ha for 3 cuts.
  • For cereals, the optimum Sulfur application rate is 50 kg SO3/ha.
  • For oilseed rape, the optimum Sulfur rate is 112 kg SO3/ha.  If using KayNitro Sulfur then an early application of DoubleTop can be used to supply more Sulfur.
  • To convert from kg product/ha to bags/acre, multiply by 0.4, then divide by 50 (e.g. 250kg product/ha X 0.4 = 100 / 50 = 2 bags/acre)
  • To convert from kg nutrient/ha to units/acre, multiply by 0.8 (e.g. 200kg N/ha X 0.8 = 160 units N/acre)

Calibrate before you spread for application rate and spread pattern

CF Fertilizers products spread to 32m bout widths. Widths of 36m are achievable with certain spreaders and products in suitable conditions, however, please seek advice. It is important to maintain fertilizer spreaders, whatever bout width you work at.

Sulphur Facts
  • Sulfur is very mobile in the soil and can leach through the soil profile. Where large amounts are required it is advisable to split the recommended requirement in two or more applications.
  • Foliar applied Sulfur is a less efficient approach to correcting Sulfur deficiency. This is because only 2% of the Sulfur is intercepted and absorbed through the leaf and often these products don’t contain enough Sulfur.
  • The average UK deposition of Sulfur is now negligible compared with the 25kg SO3 /ha/year of 20 years ago. In fact Sulfur deposition is no longer measured, due to such low levels occurring.
  • Organic manures contain Sulfur, but in variable quantity and availability. Like elemental Sulfur, most of the Sulfur in organic manures cannot be directly taken up by crops for growth.
