Wet subtropics, Salpine: Eucalyptus grandis × urophylla
In a 12-month open-field trial in Salpine, South Africa, Forest3 Rootzone was compared with standard forestry fertilization practices during Eucalyptus grandis x urophylla establishment.
At 7 months after transplanting, trees treated with Forest3 Rootzone reached a mean height of 2.4 m, compared with 2.0 m under standard fertilization practices. A +20% difference under wet subtropical conditions.

%
Greater mean tree height
At 7 months after transplanting, compared with standard forestry fertilization practices.
Forest3 Rootzone-treated trees reached 2.4 m after 7 months.
Mean height was 2.4 m with Forest3 Rootzone versus 2.0 m under standard forestry fertilization practices.
Greater early height performance under wet subtropical field conditions.
The observed height advantage was measured 7 months after transplanting during Eucalyptus grandis x urophylla establishment.

The graph compares tree height at 7 months after transplanting for trees treated with Forest3 Rootzone and those receiving standard forestry fertilization. Heights are expressed in m.
Taller trees after transplanting
At 7 months after transplanting, trees treated with Forest3 Rootzone reached a mean height of 2.4 m, compared with 2.0 m for trees receiving standard forestry fertilization. This measured difference of 0.4 m corresponds to 20% greater mean tree height under wet subtropical field conditions.
