A liquid fertiliser that provides Calcium and Sulphur nutrition for vegetables, fruits, vines, flowers, turf and ornamentals.


Campbells Thiocal supplies the plant nutrients Calcium and Sulphur, available for plant uptake. Thiocal is a true solution and is at least 500 times more soluble than Gypsum and therefore means it not only supplies plant nutrients, but acts as a soil amendment that can be used to improve water penetration and leach harmful salts from the root-zone.

Where salt (Sodium) issues are more serious, consider using Campbells Thiocal in conjunction with Valagro Retrosal.

Campbells Thiocal is ideally suited to fertigation programs, where Calcium nitrate applications are incorporated into early development of the crop, but Calcium requirements are ongoing and Nitrogen applications are required to be limited.

Campbells Thiocal:

  • Provides immediately available Calcium and Sulphur in water soluble forms
  • An ideal choice when chloride-based or nitrate-based Calcium products are not appropriate
  • Helps to control soil sodium issues and maintain productive capacity



Campbells Thiocal is a useful addition to the range of other soil amendments such as Gypsum, but as a true solution can be applied via irrigation systems at any time during the growing season


General rates for horticultural crops are between 20 to 50 L/ ha, repeating at regular intervals throughout the season, as necessary (ideally apply during middle 1/3 of the irrigation period). The actual rates, number of applications and their timing will vary considerably for different crops and for different districts.  Before application, seek advice from your Campbell’s distributor or your local agronomist.
