| Research Abstract |
In this paper, this experimental study has carried out with the situation of the visible damage and the growth reaction of saplings of ceder, Quercus serrata and sila oak by artificial rain. For 140 days, these saplings planted on the artificially acidified soil were grown in the soil acidified artificially, and last the amount of Al^<3->,Mn^<2+>,Ca^<2+>,Na^+,K^+ in the soil was analyzed to clarify the relationship between each ion and check of the growth to each sapling. Consequently, the growth response of these saplings in the soil didn't vary with the kind of Al^<3-> and Mn^<2+>, but these dry growths fell down with influencing H^+ by an increase of additional sulfur. And it was guessed that superfluous failure is reversely generated with that there are much content on Ca^<2+-> and K^+.
