CropMaster® Sulphur

CropMaster® Sulphur 27-4-4 (7SO3) is a True Granular Compound fertiliser product for grazed grass providing low levels of Phosphate and Potash with added Sulphur to enhance forage yield and quality. 

CropMaster Sulphur can also be used on arable crops where soil Phosphate and Potash indices are high.

2015 research shows that even at soil index 2/3 maintenance Phosphate applications increase grass yield.

Sulphur facts

  • Sulphur 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 applications.
  • Foliar applied Sulphur is a less efficient approach to correcting Sulphur deficiency.  This is because only 2% of the Sulphur is being intercepted and absorbed through the leaf and often these products don’t contain enough Sulphur.
  • The average UK deposition of Sulphur is now negligible compared with the 25kg SO3/ha/year of 20 years ago.  In fact Sulphur deposition is no longer measured, due to such low levels occurring.
  • Organic manures contain Sulphur, but in variable quantity and availability.  Like elemental Sulphur, most of the Sulphur in organic manures cannot directly be taken up by crops for growth.

 

BROAD RECOMMENDATION FOR APPLICATIONS TO CROPS

Grassland – Use as a general grazing fertiliser where a simple one product system is required.  Rates and number of applications vary by system and location but as a general guide apply 130-185 kg/ha CropMaster® Sulphur monthly or for each grazing.

Can be used in conjunction with spring applied EarlyBite® to build soil P and K levels, or with spring and early summer applied SingleTop® to maintain soil P and K. 

With Sulphur, 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.

Arable – CropMaster Sulphur is suitable for use in any arable crop where soil P and K indices are high and where in-season application of readily available nutrients is desired. Use in conjunction with organic manures or in combination with other CF Fertilisers products. As a sole product, it is unlikely to supply the required level of P and K to balance crop offtakes. 

PRODUCT DESCRIPTION

Ammonium Nitrate is the most efficient and predictable form of Nitrogen for UK farmers.

Ammonium Sulphate offers a readily available source of Sulphur to the growing crop.

Water soluble Phosphate provides rapid uptake to support root development and plant growth.

A True Granular Compound ensures even and accurate spread of all nutrients across the crop.

FEATURES AND BENEFITS

FEATURE

BENEFIT

Phosphate and Potash applied during the growing season

Reduces autumn workload and potentially fertiliser application costs.  Nutrients are provided when the crop uses them most efficiently giving better yields and crop quality.

Contains Ammonium Sulphate

A readily available form of Sulphur for rapid uptake - elemental Sulphur cannot be taken up directly by crops because plants only take up Sulphur in the Sulphate form.

Contains Ammonium Nitrate

AN is the most efficient Nitrogen source and the ‘Best Option for the Environment and Farming’ according to Government research.

Contains water soluble Phosphate

Crop roots will only take up Phosphorus from soil solution so providing Phosphate in a form that is over 97% water soluble ensures rapid and efficient uptake, supporting root development and plant growth.

A True Granular Compound fertiliser

Even application of all nutrients across the whole spreader bout width, which optimises nutrient use efficiency and crop response.

Manufactured at sites which are accredited to ISO 9001

Reliable product with consistent high quality every year.

CARBON FOOTPRINT AND NUMBER FOR THE PRODUCT

More Yield.  Less CO2

At CF Fertilisers we are committed to improving carbon efficiency in our production processes.  All of our products have a carbon footprint, certified by the Carbon Trust in June 2012 and reviewed annually.

CF Fertilisers has promised to reduce the footprint Nitrogen production, demonstrating an on-going commitment to carbon reduction.

The footprints for fertiliser products are given as kg CO2e per kg Nitrogen (N). Most fertiliser usage is considered on the basis of N requirement, so this allows the simplest comparison between our products for a given crop requirement.

The Carbon Footprint for CropMaster Sulphur is 4.0 kg CO2e per kg Nitrogen. Carbon Trust Logo

CALIBRATION

CALIBRATE BEFORE YOU SPREAD FOR APPLICATION RATE AND SPREAD PATTERN

CF Fertilisers 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 fertiliser spreaders, whatever bout width you work at.

For optimum results, CF Fertilisers recommends that you follow the industry standard and set up your spreader for both application rate and spread pattern for each different fertiliser that you use. Product Safety Data Sheets are available here.

Notes:

  • For grazed grass, the optimum Sulphur application rate is 60 to 70 kg SO3/ha.
  • For cereals, the optimum Sulphur application rate is 50 kg SO3/ha.
  • For oilseed rape, the optimum Sulphur rate is 112 kg SO3/ha.  If using CropMaster® Sulphur then an early application of DoubleTop® can be used to supply more Sulphur.
  • 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)
