arsenic contaminated paddy soil Raw sequence reads. soil metagenome

Silica fertilization and nano-MnO2 amendment are reported as useful approaches in lowering the accumulation of arsenic in rice grains, but the effects of silica fertilization or nano-MnO2 amendment on microbial community in paddy soil with high arsenic is still unknown. In order to elucidate this question, the structures and composition of microbial community in the paddy soil, in response to silica fertilization and nano-MnO2 amendment, were studied using pyrosequencing technique.
