Agstar Range

Agstar RangeSome of WA’s most popular cropping fertilisers are featured in the Agstar range. The products provide a balanced supply of nitrogen, phosphorus and sulphur for most farming systems.

  • Fully granulated compound fertiliser with granules mainly in the 2-4mm range
  • Balance of nitrogen, phosphorus and sulphur for a wide range of cropping situations and contains all nutrients in every granule
  • Based on Sulphate of Ammonia and have a pH of 4.8-5.2
  • Agstar Extra supplies maintenance rates of trace elements


  • Excellent handling and storage, especially in humid conditions
  • Good starter levels of nitrogen and sulphur for high potential crops
  • Ideal to be applied through air seeders and machines with peg or fluted rollers
  • Ideal supply of phosphorus for soils with a moderate to high requirement
  • Sulphate sulphur is immediately available for plant uptake
  • Other varients include Agstar Zinc (heavy soils), Agstar Copper Zinc, Agstar Copper Zinc Moly (low pH soils or where molybdenum is required) 


  • Trouble free handling and storage at seeding
  • Balanced nutrient application
  • Achieve yield and quality potential with sulphate sulphur
  • Good sulphur levels to achieve yield improve grain quality
  • Improves application rates and the localised acidity of Agstar fertilisers improve trace element availability (zinc and manganese)
  • Increased yields with improved access to immobile nutrients and greater trace element availability
  • Improves seeding timeliness and reduce product loss in storage


Agstar products may be used as a starter fertiliser for all cereal crops over a wide range of soil types and conditions. Especially suited to high potential crops with reasonably high phosphorus requirement.
