Pore‐Based Modeling of Hydraulic Conductivity Function of Unsaturated Rooted Soils

International Journal for Numerical and Analytical Methods in Geomechanics, Journal Year: 2025, Volume and Issue: unknown

ABSTRACT Mualem's approach has been widely used to predict hydraulic conductivity functions (HCFs) of bare soils if a soil water retention curve (SWRC) model is available. The assumption that holds the distribution pores spatially completely random. Under this assumption, relative ( K r ) determined by continuance probability water‐filled pores. However, not valid for rooted soils, as root growth causes particle rearrangement, and thus pore altering connectivity. After reconsidering study attempts develop new predicting HCF modeling root‐induced rearrangement resultant change in Two approaches mentioned were incorporated with root‐dependent SWRC express function matric suction. proposed was validated against nine sets measured HCFs from published studies. It found reduced mean square error (RMSE) lg 33% 53%, respectively, compared traditional model. Physically, model's effectiveness depended on texture type. In fine‐textured roots capable displacing particles, thereby causing rearrangement. Also, coarse high strength tend alter distribution. considering effects pore‐level root‐soil interaction provided significant improvement prediction unsaturated soils.

The effect of AMF combined with biochar on plant growth and soil quality under saline-alkali stress: Insights from microbial community analysis

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 281, P. 116592 - 116592

Published: June 19, 2024

Arbuscular mycorrhizal fungi (AMF) and biochar application individually can enhance plant tolerance to saline-alkali stress promote growth efficiency. However, little is known about the potential synergistic effects of their combination on improving soil quality under stress. This experiment adopted potted method explore four treatments switchgrass quality: (BC), Rhizophagus irregularis (Ri), + Ri (BR) a control without or (CK). Compared CK treatment, biomass increased by 92.4 %, 148.6 177.3 % in BC, Ri, BR treatment groups, respectively. Similarly, rhizosphere index 29.33 22.7 49.1 respective groups. The significantly altered microbial composition diversity. Notably, compared other treatments, archaeal α-diversity group showed significant decrease. relative abundance bacteria, archaea at genus level (e.g., Bacillus, Trichome candidatus_methanopenens). Network analysis that complexity closeness interactions between different taxa were stronger than with being more prominent. In summary, combined has better effect promoting stress, soil, increasing study provides new approach for efficient development utilization land.

Hydraulic characteristics and vegetation performance of the Yellow River sediment modified by biochar

Biogeotechnics, Journal Year: 2024, Volume and Issue: 2(2), P. 100070 - 100070

Published: Jan. 15, 2024

The Yellow River sediment (YRS) is an important potential soil resource for the mine land reclamation and ecological restoration in arid regions of northern China. However, it has shortcomings poor water-holding capacity needs to be modified urgently. Therefore, two types biochar, namely rice husk biochar (RHB) coconut shell (CSB), were utilized this study modify YRS compared with ash (RHA). Some engineering properties (MYRS), including pore structure, water retention, permeability, vegetation performance, investigated by considering effects dosages. Results showed that addition three materials decreased bulk density increased volume extremely micro (d<0.3μm), as well effective porosity capillary porosity, thus contributed increase sediment. Among conditioners, RHB optimal choice improving YRS. Furthermore, effect becomes more pronounced increasing application rates. With materials, permeability coefficients MYRS gradually decreased, while retention rate during evaporation significantly increased. pot experiment conditioners all had significant promoting on growth oats. In particular, plain soil, total biomass oats grown 21 days 17.46%, 32.14%, 49.60% after adding 2%, 4%, 8% RHB, respectively. This introduces a new approach using planting semi-arid areas China facilitate restoration.
