The growth of pine trees has diminished in recent years in industrial areas of Korea. Soil acidification is believed to be responsible. To study its effects, we grew seedlings of three-year-old Korean pine in brown forest soil derived from granite, which had been treated with an acid solution, for 182 days. The anion mol ratio in the solution was SO4(2-):NO3-:Cl-=5:3:2, which is the average in the total precipitation in Korea; six H+ ion concentrations in the soil were studied (0 (control), 10… CONTINUE READING
