Frequency of fertilization on mid-rotation Eucalyptus grandis plantations was evaluated on 9 sites in Colombia. After fertilization, maximum monthly growth response reached up to extra 4 m3ha-1 with a duration of four years at the most reponsive sites. The cummulative volume for a six year old responsive stand was 420 m3ha-1 compared to 280 m3ha-1. Site specific responses of fertilization indicated that low productivity sites surpased previously considered highest productivity sites when fertilization was applied.
