A modified van-Genuchten model for soil-water retention modeling by considering plant additives
Archives of Agronomy and Soil Science, 2018 Applying additives [e.g. rapeseed-oil residue (RR), wheat straw (WS), and wheat husk (WH)] to soils is a common agronomic practice used to improve soil water retention.

Modelling Soil Water Retention for Weed Seed Germination Sensitivity to Water Potential
Applied and Environmental Soil Science, 2012 Soil water retention is important for the study of water availability to germinating weed seeds. Six soil water retention models (Campbell, Brooks-Corey, four- and five-parameter van Genuchten, Tani, and Russo) with residual soil water parameter ...

Filter Paper Method for the Determination of the Soil Water Retention Curve
Revista Brasileira de Ciência do Solo, 2015 High cost and long time required to determine a retention curve by the conventional methods of the Richards Chamber and Haines Funnel limit its use; therefore, alternative methods to facilitate this routine are needed.

Irrigation and Drainage, EarlyView.ABSTRACT Crop modelling is essential for agricultural water management but often relies on simplified water balance routines that limit representation of soil moisture dynamics. To address this limitation, we developed a coupled model that integrates the 1‐D Richards equation, solved using a finite difference method into the FAO AquaCrop.

Pakistan Journal of Agricultural Sciences, 2021 The hydraulic properties of soil are very important to determine the soil relationship with water. The Soil Hydraulic Properties (SHP) are used to determine the soil water relationship as it is very crucial for estimation of water holding capacity of soil.

Land Degradation &Development, EarlyView.ABSTRACT Soil compaction poses a significant threat to soil quality and sustainability, necessitating advanced assessment methods. We hypothesized that incorporating x‐ray computed tomography (XCT)‐derived pore characteristics with hydraulic properties would significantly enhance the development of a soil quality index (SQI) under soil compaction ...

Investigating the performance of the differential evolution algorithm in estimating soil hydraulic parameters [PDF]
مدلسازی و مدیریت آب و خاکIntroduction The soil water curve is one of the most critical soil hydraulic characteristics. This characteristic is used to determine soil water in the field capacity point and the permanent wilting point (PWP) beside it has a vital role in the ...

Land Degradation &Development, EarlyView.ABSTRACT Afforestation in the desert–oasis ecotone induces soil desiccation and secondary salinization. However, the seasonal dynamics of soil water–heat–salt interactions across plantations of different stand ages in arid regions remain unclear. Here, we investigated the seasonal patterns and coupled relationships of soil water–heat–salt dynamics in ...

Land Degradation &Development, EarlyView.ABSTRACT Ditch‐buried straw return (DB) is an innovative practice combining deep tillage and straw incorporation. This study aimed to evaluate its effects on soil physical quality compared to rotary tillage (RT) and identified key constraints to crop in sandy‐loam and clay‐loam paddy soils within rice–wheat systems. Two field experiments were conducted
