Cal-BOOST is a fertilizer containing nitrogen, calcium, magnesium, potassium and sulphur specially designed for new substrates. To get the best out of Cal-BOOST, combine it with standard Osmocote dose rates in new growing media. In fact it is developed for use in peat-free and peat-reduced substrates, in case of nitrogen draw down as well as when/if extra calcium and magnesium are needed or result beneficial in production. In case of substrates with less lime, use Cal-BOOST to increase Ca level. Its mini granules grant optimal distribution in growing media. The coated nitrogen (urea) allows a 2-3 month longevity. Calcium, magnesium, potassium and sulphur come available over a period of 6-8 weeks.

  • Coated N for optimal nutrient use efficiency
  • Greener leaf color thanks to N, Ca, Mg and S
  • Plant result more bushy and well branched as well as stronger and more resilient
  • Higher Calcium level in substrate, contributing to plant quality

Contact your ICL advisor for more detailed advice. Run trial first on a small scale before changing the rate, application, or any other variables. As circumstances can differ and as the application of our products is beyond our control, ICL cannot be held responsible for any adverse results.

1
Use in peat reduced or peat free growing media
2
Use in combination with standard Osmocote 5, Osmocote Exact or Osmocote Pro dose rate
3
Lower the general dose rate in indoor or hot climate situations or in peat based substrates without/low nitrogen draw down
4
Application by mixing or topdress (no planthole dibbling)
5
Water directly after application.
6
Reduce the starter fertilizer dose rate to maximum 0,5 kg/m3
7
Do not add extra nitrogen products like Osmocote-N, slow-release N, calcium nitrate or other N sources
8
Consider to increase dose rate of Micromax Premium if you lower dose rate of starter fertilizer (less traces in mix) to compensate
9
Do not use in Boron susceptible crops because product contains some boron
