Spatial predictions of the permanent wilting point in arid and semi-arid regions of Northeast China

Journal of Hydrology, 2018
Abstract The permanent wilting point (PWP) is the minimal point of soil moisture a plant requires not to wilt. If moisture decreases to this, or any lower point, a plant wilts, and can no longer recover its turgidity when placed in a saturated atmosphere for 12 h.

Perlis State Soil Series: Plant Available Water, Field Capacity, Permanent Wilting Point, and its Uncertainty

Journal of Advanced Research in Fluid Mechanics and Thermal Sciences, 2022
Hydrological cycle is affecting the recycling of water in the human sphere. A smaller scale of the environment like Perlis state is also in constant exchange of water with its surrounding environment like atmospheric air, soil, groundwater, lake, and river. This study focusses on the Perlis state soil.

Estimating Permanent Wilting Point in the Field by a Direct Laboratory Calibration

Soil Science Society of America Journal, 1958
Abstract A method is described whereby soils may be calibrated with fiberglass soil moisture units at 15‐atm. tension using the pressure membrane apparatus. Moisture units to be installed in the field were first calibrated in a shallow pan with a bulk soil sample taken from the site of the proposed field installation.

Estimation of soil water content at permanent wilting point using hygroscopic water content

European Journal of Soil Science, 2019
Abstract Traditional methods for determining soil water content at permanent wilting point (θ PWP ) are time consuming. The objectives of this study are to develop a model for predicting θ PWP

Estimation of soil texture from permanent wilting point measured with a chilled‐mirror dewpoint technique

Journal of Plant Nutrition and Soil Science, 2018
Abstract Soil texture is an important factor governing a range of physical properties and processes in soil. The clay and fine fractions of soil are particularly important in controlling soil water retention, hydraulic properties, water flow and transport.

Permanent wilting point plays an important role in simulating winter wheat growth under water deficit conditions

Agricultural Water Management, 2020
Abstract Soil parameters related to soil water holding capacity could play an important role in simulating winter wheat growth under severe soil water stress, which could heavily influence the simulated soil water contents, and then biomass and final yield.

Modelling and prediction of soil water contents at field capacity and permanent wilting point of dryland cropping soils

Soil Research, 2011
Field capacity (FC) and permanent wilting point (PWP) are two critical input parameters required in various biophysical models. There are limited published data on FC and PWP of dryland cropping soils across north-western Victoria. Direct measurements of FC and PWP are time-consuming and expensive.

Soil aggregates structure-based approach for quantifying the field capacity, permanent wilting point and available water capacity

Irrigation Science, 2019
Soil plays a pivotal role in enhancing global water and food security. Irrigation water constitutes more than 70% of the global water demand. The anticipated demographic increase and changing climate will impose more pressures on the global water and food systems.

Performance Evaluation of Pedotransfer Functions to Predict Field Capacity and Permanent Wilting Point Using UNSODA and HYPRES Datasets

Arid Land Research and Management, 2015
Using basic soil properties could save time and costs in determining field capacity (FC) and permanent wilting point (PWP). The objectives of this study were to investigate the relationship between FC and PWP and basic soil properties, develop two new equations for estimating FC and PWP, and evaluating their performance as compared to some existing ...
