Description
Five kinds of grasses which are common in Hokkaido were studied for the purpose of comparing these grasses' tolerances to soil acidified mainly by fertilyzer anions. The experiments were separated into categories, : aluminum tolerance (pot experiment) and tolerance to acidic soil (pot and field experiments). Orchardgrass, Timothy and Perennial ryegrass showed strong tolerances and Ladino clover showed weak tolerance in each experiment. Although Alfalfa showed a weak tolerance in the pot experiment it was not as weak in the field. In this experiment the role of the root system seemed to be very important. That is, in the case of Ladino clover, it showed a sensitive reaction to the acidifying of grassland soil, because of a very small root mass and a weak tolerance to acidity. On the contrary in the case of Alfalfa, because of its deep, and steady root system, its weakness to acidity did not appear in the field.
