Foliarel is the fertiliser with the highest Boron content on the market. The chemical make up of Foliarel is Disodium Octaborate Tetra Hydrate or Sodium Borate however a superior production process typically results in a higher percentage of Boron than other producers.
Foliarel 21% B is a Sodium borate with a Boron content of 21% It comes in the form of a very fine powder, perfectly soluble even in cold water. Boron is necessary for the following essential plant functions:
- Cell division
- Pollination and fruit setting
- Translocation of sugars and other plant metabolites
- Symbiotic fixation of nitrogen in leguminous plants
- Resistance to cold and phytopathogens
Boron deficiencies are common in sandy or clay soils, soils with pH below 5.5 and above 7.5, in soils with low organic matter, or high irrigation/rainfall.
Foliarel 21% B is fully water soluble, suitable for foliar, fertigation and hydroponic application for prevention and cure of Boron deficiencies. With its high solubility it is suited to produce solutions with low water volumes and in combination with other fertilisers.
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 Campbells distributor or your local agronomist.
