Abstract
To a highly acidic mineral soil of tertiary origin added CaCO_3 in ascending rates of amount and cultivated barley, italian millet, wheat and spinach. From the experimental results the following summaries are briefly given ; 1. The barley grows best on the soil which contains good supply of lime and react neutral or slightly basic. 2. The italian millet grows best on the soil with moderate supply of lime and with reaction between weakly acidic and slightly basic. But it can thrive fairly good on the soil of wide range of reaction from highly acidic to basic. 3. The wheat behaves almost alike with barley, but it is somewhat more acid tolerant than the latter. 4. The spinach grows best on the soil of weak acid and neutral reaction with moderate supply of exchangeable lime. It fails to thrive both on the highly acidic soil and also on the basic soil with plentiful lime content.
