Abstract Soil field capacity (FC) and permanent wilting point (PWP) are significant parameters in numerous biophysical models and agricultural activities. Although these parameters can be measured directly, their measurements are quite expensive. The purpose of this study was to develop a hybrid Support Vector Machine (SVM) combined with Firefly ...

The purpose of this paper was to evaluate the performance of pedotransfer functions generated by Radial Base Function (RBF) Artificial Neural Network (ANN) to estimate soil water retention at field capacity (FC, suction at −30 kPa) and Permanent Wilting Point (PWP, −1500 kPa) for soils at PROJIR area -RJ/BR.

Impacts of Soil Type and Crop Species on Permanent Wilting of Plants
Geoderma, 2021 The lack of a continuous network of water-filled pores necessary for the flow of water in the soil has been related to the wilting of plants as well as to the limitations of soil sample equilibrium in pressure plates.

Soil field capacity (FC) and permanent wilting point (PWP) are important input parameters in many bio- physical models. Although these parameters can be mea- sured directly, their measurement is quite difficult and expensive. Pedotransfer functions (PTFs) provide an alternative by estimating soil parameters from more readily available soil data.

A New Computational Approach for Estimation of Wilting Point for Green Infrastructure
Measurement: Journal of the International Measurement Confederation, 2017 Wilting point is an important parameter indicating the inhibition of plant transpiration processes, which is essential for green infrastructure. Generalization of wilting point is very essential for analyzing the performance of even green infrastructure (

SIMPLE DEVICE FOR ESTIMATING SOIL WATER CONTENT AT PERMANENT WILTING POINT
Acta Horticulturae, 2003For irrigation management, soil water content at permanent wilting point is generally estimated by the soil water content at -1.5 MPa (W 15 ). However, the measurement of W 15 needs a special device whereas its estimation needs to know some characteristics of the soil.

Field capacity (FC) and permanent wilting point (PWP) are two important properties of the soil when the soil moisture is concerned. Since the determination of these parameters is expensive and time-consuming, this study aims to develop and evaluate a new hybrid of artificial neural network model coupled with a whale optimization algorithm (ANN-WOA) as ...

Spatial predictions of the permanent wilting point in arid and semi-arid regions of Northeast China
Journal of Hydrology, 2018Abstract 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.

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.
