Abstract
Carbon material such as graphite and activated charcoal can promote the growth of some formsog bacteria. We examined whether this bacterial growth promoting effect can have a positive influence on field crops. Refined graphite was mixed into the standard soil used in rice cultivation. Varying soil graphite mixtures of 0.1%, 0.5% and 1% were used to cultivate rice seedling for 3 weeks. After transplanting in the filed, rice plants were cultivated for 4 months. To observe the effect of graphite(carbon material) during the cultivation of rice, we examined various different growth components in this research. During the transplanting stage, growth promoting effect of carbon was observed in the 0.1% carbon added soil. However, there were not much difference between graphite added soil and standard soil in the other stages. Rice yield was highest in the soil with 0.1% graphite.
