Effects of alfalfa and oatgrass on soil nutrients in newly cultivated land on the Loess Plateau, China [PDF]

Scientific Reports
Some newly cultivated land formed by “ditch and make land” on the Loess Plateau has poor soil nutrient, low fertility and unsustainable development. Medicago falcata L. and Arena sativa L. were selected as experimental subjects to investigate the effects

Comprehensive analysis of the influence of loess structure on strength on the Loess Plateau, China. [PDF]

PLoS One
This study examines the influence of loess structure on strength by selecting three representative regions of the Loess Plateau in northern Shaanxi as the research area. Malan loess serves as the test subject, and in-situ direct shear tests, particle flow modeling, and theoretical analysis are employed to investigate the impact of loess structure on ...

Genesis of Loess Particles on the Chinese Loess Plateau

Geochemistry, Geophysics, Geosystems, 2022
AbstractThe sources of the sediments in distinct areas of the Chinese Loess Plateau (CLP) are still disputed, starting with the particle formation in the original desert areas, as well as the neighboring river systems. The formation of loess particles in the southern CLP was investigated using Scanning Electron Microscopy (SEM) and combined material ...

Hydrogen sulphide alleviates iron deficiency by promoting iron availability and plant hormone levels in Glycine max seedlings

BMC Plant Biology, 2020
Background Hydrogen sulphide (H2S) is involved in regulating physiological processes in plants. We investigated how H2S ameliorates iron (Fe) deficiency in soybean (Glycine max L.) seedlings.

Arbuscular Mycorrhizal Fungi Alleviate Low Phosphorus Stress in Maize Genotypes with Contrasting Root Systems

Plants, 2022
Soil available phosphorus (P) is one of the main factors limiting plant growth and yield. This study aimed to determine the role of arbuscular mycorrhizal fungi (AMF) in P-use efficiency in two maize genotypes with contrasting root systems in response to
