Wet subtropics, KwaZulu-Natal: Eucalyptus grandis x urophylla
In a 12-month open-field trial in KwaZulu-Natal, South Africa, Forest3 Rootzone fertilization was compared with standard forestry fertilization practices during Eucalyptus grandis x urophylla establishment.
Under wet subtropical field conditions, mean tree height was 17% greater at 7 months (+24 cm) and 8% greater at 11 months (+36 cm) after transplanting, compared with standard forestry fertilization practices.
Key conclusions
+17
%
Greater mean tree height
At 7 months after transplanting, compared with standard forestry fertilization practices.
Trees treated with Forest3 Rootzone were 24 cm taller after 7 months.
A 17% increase in mean tree height compared with standard forestry fertilization practices.
The height advantage was also observed at 11 months after transplanting.
Forest3 Rootzone-treated trees were 36 cm (8%) taller on average than trees receiving standard forestry fertilization practices.

Field performance
Tree height is an important indicator of early stand development during Eucalyptus establishment. This 12-month open-field trial compared Forest3 Rootzone with standard forestry fertilization practices under wet subtropical conditions in KwaZulu-Natal, South Africa. Mean tree height was assessed at 7 and 11 months after transplanting.
Taller trees after transplanting
At 7 months after transplanting, trees treated with Forest3 Rootzone were 24 cm taller (+17%) than trees treated with standard forestry fertilization practices. At 11 months, the mean tree height advantage was 36 cm (+8%) compared with standard forestry fertilization. These results refer to two measurement points within a 12-month open-field trial.
Mean tree height difference compared with standard forestry fertilization at 7 and 11 months after transplanting.
