Conservative Agriculture Based on Irrigation Increased the Connections in Inter-Kingdom Co-Occurrence Networks in Arid Zones of Argentina
Background
Water is one of the most important natural resources in agricultural systems, and the adoption of irrigation systems is producing the expansion of the productive agriculture frontier in Northern Patagonia's arid zone (Argentina). It is critical to evaluate how agricultural management shapes this soil process, like soil microbial communities, nutrient transformation, and ecosystem functions.
Aims
For this reason, we analyzed how converting from a semi-arid steppe to an irrigated agricultural system based on no-till and crop rotations impacted the soil microbiome (bacteria and fungi), focusing on the soil core microbiome and the connections between the soil members.
Methods
Soil microbiota was analyzed by soil DNA amplicon sequences V3-V4 region of 16S rRNA for bacteria and ITS1–5F region of the ITS rRNA for fungi. Soil enzymes, aggregation, and chemical properties were analyzed related to microbiota structure.
Results
Our results suggest that irrigated agriculture enhanced the connections between members but not the number of network members per se. Additionally, we were able to identify a soil core microbiome, which played an important role in the co-occurrence networks.
Conclusions
We concluded by demonstrating the critical role that the core microbiome plays in preserving soil bacterial–fungal interactions and their influence on inter-kingdom relationships in complex microbial soil ecosystems in the arid zones of northern Patagonia.
期刊介绍:
Established in 1922, the Journal of Plant Nutrition and Soil Science (JPNSS) is an international peer-reviewed journal devoted to cover the entire spectrum of plant nutrition and soil science from different scale units, e.g. agroecosystem to natural systems. With its wide scope and focus on soil-plant interactions, JPNSS is one of the leading journals on this topic. Articles in JPNSS include reviews, high-standard original papers, and short communications and represent challenging research of international significance. The Journal of Plant Nutrition and Soil Science is one of the world’s oldest journals. You can trust in a peer-reviewed journal that has been established in the plant and soil science community for almost 100 years.
Journal of Plant Nutrition and Soil Science (ISSN 1436-8730) is published in six volumes per year, by the German Societies of Plant Nutrition (DGP) and Soil Science (DBG). Furthermore, the Journal of Plant Nutrition and Soil Science (JPNSS) is a Cooperating Journal of the International Union of Soil Science (IUSS). The journal is produced by Wiley-VCH.
Topical Divisions of the Journal of Plant Nutrition and Soil Science that are receiving increasing attention are:
