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

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.

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.

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.

Pedotransfer functions for estimating the field capacity and permanent wilting point in the critical zone of the Loess Plateau, China

Journal of Soils and Sediments, 2018
Field capacity (FC) and permanent wilting point (PWP) are important physical properties for evaluating the available soil water storage, as well as being used as input variables for related agro-hydrological models. Direct measurements of FC and PWP are time consuming and expensive, and thus, it is necessary to develop related pedotransfer functions ...

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.

Determination of water content at permanent wilting point in a large set of soils

Master thesis of Lorenzo Ceriscioli, conducted at the Università degli Studi Mediterranea di Reggio Calabria (Italy) together with Agroscope (Switzerland) Summary Modern agriculture faces challenges that no longer concern only the sphere of economic sustainability of production per se, but rather socio-environmental issues that claim to place it at ...
