Physical and Microbiological Properties of Alfalfa-Established Soil in the Semiarid Horqin Sandy Land in Northern China

引用

Journal of Environmental Protection 2024年第4期15卷 439-449页

作者： Yumei kang Tatsuya Kawazawa Taisei Kono Jun Kawamoto Yong zhang Faculty of Agriculture and Marine Science Kochi University Nankoku Japan Institute for Chemical Research Kyoto University Kyoto Japan College of Resources and Environment Southwest University Chongqing China

In a previous article, we reported that a local variety of alfalfa (Medicago sativa L. cv. Aohan) had high potential to be a pioneer plant for ecological restoration in the Horqin Sandy Land, China. The plantation of Aohan significantly improved the organic matter, clay, total carbon and nitrogen contents of the soils. In this study, we investigated the physical properties such as dispersion ratio, water-stable aggregates content, and the soil microbiomes, five years after alfalfa establishment in the same study site. We found no significant difference in the dispersion ratios between the soils before and after alfalfa establishment, and all the soils at the study site were erosive. Water stable aggregates mainly distributed in 96%, suggesting that it would take longer time for improving soil structure. However, large-size aggregates (2 - 5 mm) content was slightly higher in the alfalfa planting plots. This slight increase is presumed to have long-term importance for soil and ecosystem recovery in semi-arid areas like Horqin Sandy Land. Moreover, we also found that Actinomycetes dominated the microbial community in both bulk and rhizosphere soils, and two kinds of rhizobia, Bradyrhizobium and Sinorhizobium fredii, were identified in the rhizosphere soil.
