Effects of different irrigation methods on micro-environments and root distribution in winter wheat fields

Journal of Integrative Agriculture, 2015
The irrigation method used in winter wheat fields affects micro-environment factors, such as relative humidity (RH) within canopy, soil temperature, topsoil bulk density, soil matric potential, and soil nutrients, and these changes may affect plant root ...

Vegetation Improves Hydro‐Mechanical Soil Resilience on Humid Tropical Slopes: Field Evidence for Sustainable Land Management

Land Degradation &Development, EarlyView.
ABSTRACT Landslides represent a recurring hazard in humid tropical regions, primarily driven by intense rainfall that weakens slope materials and reduces shear resistance. Vegetation is widely promoted as a nature‐based solution to improve near‐surface soil conditions; however, systematic field‐based hydro‐mechanical evidence from humid tropical ...

Soil water isotherm model for particle surface sorption and interlamellar sorption

Vadose Zone Journal, 2022
Soil–water retention curve (SWRC) describes the relationship between soil matric potential and soil water content, which is recognized as the most important constitutive function for unsaturated soil that governs many hydrological and mechanical ...

Ditch‐Buried Straw Return Improves Soil Physical Quality and Crop Biomass in Two Rice–Wheat Paddy Soil Systems

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

Determining the Optimal Water Storage Depth of Apple Orchards in the Chinese Loess Plateau: Balancing Soil Desiccation Mitigation, Plant Utilization, and Engineering Construction

Land Degradation &Development, EarlyView.
ABSTRACT Deep‐rooted plantations are central to dryland ecological restoration, yet their long‐term cultivation drives widespread deep soil desiccation, threatening ecosystem sustainability. While artificial water replenishment is a key deep soil desiccation mitigation strategy, the depth‐dependent positional effect of stored water on eco‐hydrological ...

Pressure Dependence of Soil Water Matric Potential

, 1963
The partial specific Gibbs1 free energy or the chemical potential has been shown to be the most desirable thermodynamic function for describing soil-water systems. The absolute value of the chemical potential of soil water cannot be determined. If pure water at standard temperature and pressure is taken as the reference, the difference between the ...

Low-Cost Control and Measurement Circuit for the Implementation of Single Element Heat Dissipation Soil Water Matric Potential Sensor Based on a SnSe₂ Thermosensitive Resistor

Sensors, 2021
A low-cost signal processing circuit developed to measure and drive a heat dissipation soil matric potential sensor based on a single thermosensitive resistor is demonstrated. The SnSe2 has a high thermal coefficient, from −2.4Ω/°C in the 20 to 25 °C to −

Salt leaching of heavy coastal saline silty soil by controlling the soil matric potential [PDF]

Soil and Water Research, 2019
Techniques of drip irrigation are broadly applied for the reclamation of saline-alkali lands, during which effective management of water use to accelerate salt leaching is essential for crop production. In 2017, a field experiment with five treatments of soil matric potential (SMP) levels of -5, -10, -15, -20, and -25 kPa was conducted in heavy saline ...

Innovations in polysaccharide‐based hydrogels in sustainable agriculture

Polymer International, EarlyView.
Polysaccharide‐based hydrogels are promising in sustainable agriculture, as these natural polymers have the ability to absorb water and nutrients and release them gradually in the soil, in addition to ensuring biodegradability and lower cost. However, some challenges still need to be overcome.

Quantification of flash flood peaks using computer simulation for potential hill torrents of Pakistan: A modeling study

River, EarlyView.
Abstract This study investigates rainfall runoff behavior of five major torrential Nullahs' of Dera Ghazi Khan (D. G. Khan) for flash flood events. The integration, and fusion of satellite‐based meteorological, topographical, and pedo‐transferred function's (PTF) derived soil hydraulic datasets at 250 m grid size substantially proves a viable approach ...
