A global dataset of remote sensing-based soil critical point and permanent wilting point [PDF]

Scientific Data
The critical point (CP) and permanent wilting point (PWP) are key soil hydraulic characteristics that control the land surface energy budget and water balance. There is a lack of available data for these parameters on the global scale.

Determination of the Permanent Wilting Point of Physalis peruviana L.

Horticulturae, 2023
The soil–water potential limit, or permanent wilting point (PWP), of Physalis peruviana L. is not known. Thus, determining the PWP of P. peruviana in different soils is essential to plan crops and manage irrigation in order to optimize the use of water ...

The role of the permanent wilting point in controlling the spatial distribution of precipitation. [PDF]

Proc Natl Acad Sci U S A, 2018
Significance One basic distinction between land and ocean is that the land can dry out. We show that this is of fundamental importance for the precipitation distribution over land as it brings precipitation from the precipitating region to the nonprecipitating region.

Permanent wilt point from two methods for different combinations of citrus rootstock [PDF]

Ciência Rural, 2020
: Considering that water is extremely important in agricultural production, but with restricted availability in some Brazilian regions, this research sought to identify the water limit for the rootstocks: Cleóptra tangerine (Citrus reshni hort.

Particle Size Distribution as a Basic Characteristic for Pedotransfer Prediction of Permanent Wilting Point

Agricultural Science and Practice, 2014
The permanent wilting point (PWP) belongs to the basic soil hydrological constants and plays the important role in an estimation of the natural or irrigating moisture availability to agricultural plants.

Geostatistical approach as a tool for estimation of field capacity and permanent wilting point in semi-arid terrestrial ecosystem

Archives of Agronomy and Soil Science, 2018
ABSTRACTThe understanding of spatial and seasonal variability in soil water retention properties is critical for careful management of soil water in agricultural production in semi-arid regions. The main objectives of this study were to spatially predict and prepare distribution maps of the field capacity and permanent wilting point in semi-arid ...

Prediction of Soil Field Capacity and Permanent Wilting Point Using Accessible Parameters by Machine Learning

AgriEngineering
The field capacity (FC) and permanent wilting point (PWP) are fundamental hydrological properties critical for assessing water availability within soils, rather than direct measures of soil health.
