A study was carried out in the Grand'Mère plantations on the 10-year growth response from a fertilization trial with various levels of nitrogen and potassium. There was a growth response to potassium at the end of the experiment, while the effect of nitrogen was less apparent. The best four treatments, K 2 , N 2 K 2 , N 1 K 1 and K 1 , produced respectively 27.8, 26.9, 14.7 and 12.6 cubic meters per hectare (4.0, 3.8, 2.1 and 1.8 cunits per acre) of extra wood.
