ABSTRACT
500 trees, at two localities were treated with different
concentrations of H2SO4 in solution and paste form in
conjunction with American bark hack method. The
conventional French method of tapping with and without
10% sodium chloride solution was also used. Increase in
diameter of the trees under each treatment was measured
after 5 year and it turned out that acid treatments had
not adversely affected the tree growth. Also no tree
died due to acid treatment.
