  • distinct effects of short term reconstructed topsoil on soya bean and corn rhizosphere bacterial abundance and communities in chinese Mollisol
    Royal Society Open Science, 2019
    Co-Authors: Jian Jin, Yue Yang, Yue Zhao, Changkai Liu, Xiaobing Liu
    Abstract:

    Eroded black soils (classified as Mollisols) lead to a thinner topsoil layer, reduced organic carbon storage and declined crop productivity. Understanding the changes in soil microbial communities owing to soil erosion is of vital importance as soil microbial communities are sensitive indicators of soil condition and are essential in soil nutrient cycling. This study used the reconstructed facility with 10, 20 and 30 cm topsoil thickness under no-till soya bean-corn rotation in black soil region of Northeast China. Illumina MiSeq sequencing targeting 16S rRNA, qPCR and soil respiration measurement were performed to assess the changes in soya bean and corn rhizosphere bacterial communities, as well as their abundance and activities due to the topsoil thickness. The results showed that soil bacterial communities from both soya bean and corn were more sensitive to topsoil removal than to soil biogeochemical characteristics. Topsoil depths significantly influenced both soya bean and corn bacterial communities, while they only significantly influenced the bacterial abundance and respiration in corn. We also found that the topsoil depths significantly induced the changes in phyla and genera from both soya bean and corn rhizosphere bacterial community, which aid further understandings on how topsoil layer influences the global nutrient cycling of Mollisols by influencing the change in microbial communities.

    Co-Authors: Tufaila M, La Mpia, Karim Jufri
    Abstract:

    Soil water balance is describes the condition of the water in an area. The difference of climatic conditions and land characteristic denotes the effect of the soil water balance. The objective of this study is to determine soil water balance on the type of soil that developed at parent material karts. Village Parigi district Muna has an area of 16245.88 ha consists of Inceptisol, Mollisol, and Andosol and developing in Qal and Qpw geological formation. The results of research showed that surplus on rainwater occurred in February, March, and April. While the water deficit occurred in January, May, June, July, August, September, October, November, and December. Soil water balance in the research site was affected by climate, soil condition, and soil characteristic. Soil was formed above the karst rock showing little effect on the soil water balance. ABSTRAK Neraca air lahan menggambarkan kondisi air pada suatu wilayah.
