Effects of root systems on crack formation: experiments, modeling, and analyses Soil Tillage Res. (IF 7.366) Pub Date : 2023-06-02 Rui Nong, Yukuai Wan, Yimin Ding, Mingtang Chai, Lei Zhu
Plant roots can increase soil shearing resistance directly by mechanical reinforcing. The 2D crack pattern of the surface soil near the plant were observed experimentally, and it was found that the soil cracking near the plant roots was inhibited, which may be due to the influence of the plant roots. This paper focuses on the mechanical reinforcement of soil by plant roots and investigates the development

Impacts of straw return coupled with tillage practices on soil organic carbon stock in upland wheat and maize croplands in China: A meta-analysis Soil Tillage Res. (IF 7.366) Pub Date : 2023-06-02 Mahbub Ul Islam, Fahui Jiang, Zichun Guo, Shuai Liu, Xinhua Peng
Despite numerous individual studies evaluating the impact of straw return on soil organic carbon (SOC) stock in upland wheat and maize croplands in China using no-tillage (NTS), rotary tillage (RTS), and deep tillage (DTS) practices, the results have shown inconsistency. In addition, several factors influence the effects of various tillage practices with straw return on SOC stock that are not well

To describe various important soil processes like the release of greenhouse gases or the proliferation of microorganisms, it is necessary to assess quantitatively how the geometry and in particular the connectivity of the air-filled pore space of a soil evolves as it is progressively dried. The availability of X-ray computed microtomography (μCT) images of soil samples now allows this information to

Digital soil mapping (DSM) typically requires three common ingredients: georeferenced samples, environmental covariates, and a model. Of the three, sample design, or the selection of sample size and locations, has received considerably less attention. This is not surprising given that most studies are primarily limited by budget, the result being a focus on stratification of sampling locations in covariate

Plastic film mulching (PFM) is critical for agricultural planting and maximizing production in semiarid and arid areas. Particulate organic matter (POM) is assumed to be a sensitive indicator of evaluating the effects for different agricultural practices on soil fertility and the soil organic carbon (SOC) pool. Soil aggregates have the function of “wrap” and protect the POM stored in them. However

Empirical evidence for the positive relationship between tree species richness and wood decomposition is weak, despite the greater numbers of decomposers in diverse stands. Tree species identity affects decomposition rates strongly by altering soil communities and micro-environments. It is therefore likely that tree species richness influences spatial variation rather than the mean rate of decomposition

Thermal conductivity is a key parameter characterizing heat and water transfer in soils. It is difficult to measure thermal conductivity under freezing conditions. For this reason, some models have been proposed to estimate the thermal conductivity of freezing soils, but most of them failed to mimic the variation of thermal conductivity with temperature.

Storage and controlling factors of soil organic carbon in alpine wetlands and meadow across the Tibetan Plateau Eur. J. Soil Sci. (IF 4.178) Pub Date : 2023-05-25 Xiuqing Nie, Dong Wang, Guoying Zhou, Lining Ren, Yangong Du
Alpine wetlands and meadow across the Three Rivers Source Region (TRSR) store high soil organic carbon (SOC). However, information on factors affecting SOC storage is scanty. Herein, we investigated SOC storage and explored factors affecting SOC storage, including climate, soil properties, above- and belowground biomass, using 50 soil profiles across the TRSR on the Tibetan Plateau. The SOC storage
