Rhizodeposition efficiency of pearl millet genotypes assessed on a short growing period by carbon isotopes (δ13C and F14C) Soil (IF 6.373) Pub Date : 2022-01-20 Papa Mamadou Sitor Ndour, Christine Hatté, Wafa Achouak, Thierry Heulin, Laurent Cournac
Rhizosheath size varies significantly with crop genotype, and root exudation is one among its driving factors. Unravelling the relationships between rhizosheath formation, root exudation and soil carbon dynamics may bring interesting perspectives in terms of crop breeding towards sustainable agriculture. Here we grew four pearl millet (C4 plant type: δ13C of −12.8 ‰, F14C = 1.012) inbred lines showing

Are agricultural plastic covers a source of plastic debris in soil? A first screening study Soil (IF 6.373) Pub Date : 2022-01-19 Zacharias Steinmetz, Paul Löffler, Silvia Eichhöfer, Jan David, Katherine Muñoz, Gabriele E. Schaumann
Agricultural plastic covers made from polyethylene (PE) and polypropylene (PP) provide increased yields and an improved crop quality. However, such covers are suspected of partially breaking down into smaller debris and thereby contributing to soil pollution with microplastics. To scrutinize this, we randomly sampled 240 topsoil cores (0–5 cm) from eight fields which were covered with fleeces, perforated

Lower functional redundancy in “narrow” than “broad” functions in global soil metagenomics Soil (IF 6.373) Pub Date : 2022-01-13 Huaihai Chen, Kayan Ma, Yu Huang, Jiajiang Lin, Christopher Schadt, Hao Chen
Abstract. Understanding the relationship between soil microbial taxonomic compositions and functional profiles is essential for predicting ecosystem functions under various environmental disturbances. However, even though microbial communities are sensitive to disturbance, ecosystem functions remain relatively stable, as soil microbes are likely to be functionally redundant. Microbial functional redundancy

Phosphorus dynamics during early soil development in a cold desert: insights from oxygen isotopes in phosphate Soil (IF 6.373) Pub Date : 2022-01-12 Zuzana Frkova, Chiara Pistocchi, Yuliya Vystavna, Katerina Capkova, Jiri Dolezal, Federica Tamburini
At the early stages of pedogenesis, the dynamics of phosphorus (P) in soils are controlled by microbial communities, the physicochemical properties of the soil and the environmental conditions. While various microorganisms involved in carrying out biogeochemical processes have been identified, little is known about the actual contribution of microbial processes, such as organic P hydrolysis and microbial

Polyester Microplastic Fibers affect Soil Physical Properties and Erosion as a Function of Soil Type Soil (IF 6.373) Pub Date : 2021-12-14 Rosolino Ingraffia, Gaetano Amato, Vincenzo Bagarello, Francesco G. Carollo, Dario Giambalvo, Massimo Iovino, Anika Lehmann, Matthias C. Rillig, Alfonso S. Frenda
Abstract. Microplastic is recognized as a factor of global change affecting many environmental compartments. Agricultural soils are likely hotspots of microplastic contamination in terrestrial ecosystems and are of particular concern due to their role in food production. Microplastic has already been shown to be able to affect soil properties, but its effect on different soil types is poorly understood
