A fully soluble fertiliser containing Nitrogen and Sulphur recommended for vegetables, fruits, flowers, turf, vines and ornamentals.

Nutrient Form:

Campbells Solu-Sam is a fully water soluble, chloride free fertiliser containing Ammonium Nitrogen and Sulphur nutrition for consistent growth responses on a range of plants. Nitrogen plays an important role in the growth and vigour of fruit and vegetable crops.


Solu-Sam is of high purity, highly soluble, and particularly important for:

  • Quick greening of crops, particularly turf and leafy vegetables
  • Where Nitrogen and Sulphur are required
  • Promoting growth and vigour
  • Crops requiring a low pH such as blueberries


Campbells Solu-Sam is suitable where Nitrogen and Sulphur requirement is high and supply is lacking. Solu-Sam is for application via irrigation systems (fertigation) in soil grown crops. It dissolves rapidly and completely and remains in solution ready for root adsorption.


General fertigation rates for horticultural crops are between 25 to 50 kg/ha through the fertigation system. When applying Solu-Sam through the irrigation system more frequently and smaller applications guarantee the nutrients are supplied to the plants without being lost due to leaching or excessive rainfall. The actual rates, number of applications and timings for specific crops will vary considerably between crops and districts. As with any fertiliser program, it is best to seek advice from your Campbell’s distributor or your local agronomist.
