On the relation between the reaction of soil and the germination and growth of Digitaria ciliaris Pers

Abstract: 1. The author reported the experiment on the effect of soil reaction upon the germination and growth of Digitaria ciliaris Pers.2. A strong acid mineral soil originated from tertiary strata was used for this experiment, to this soil several amounts of CaCO3 (ranging O.-1.4% of the soil) was added, so as every part to the soil indicated respectively a pH value of 5.0-8.0, and the plants were cultivated in unglazed pots contaiing soil with respective pH values above mentioned.3. The seed sprouts earlier by some extent on the soil of pH value of 5.0-5.5 than that of 6.0-8.0, and the optimum reaction for germination of seeds is probably pH 5.5.4. A soil of pH value of 5.3-7.5 was favorable for the growth of that plant having the optimum point at pH 6.0-7.0 but the soil with pH values below 5 as well as above 8 seemed decidedly unfavorable.5. Mesurements of reaction of soil before and after the cultivation showed that there is a general tendency to result in a decrease in a hydrogen-ion concentration of the soil during this experiment.
