Pedotransfer functions for predicting soil-water retention under Brazilian Cerrado

Pesquisa Agropecuária Brasileira, 2022
The objective of this work was to determine pedotransfer functions to predict water retention at the -33 and -1500 kPa matric potentials of soils under Cerrado, in the south of the state of Mato Grosso, Brazil.

Global maps of soil water-retention parameters (field capacity and permanent wilting point) at different soil depths

, 2021
Global maps (at the 10 km resolution) of field capacity and permanent wilting point at different soil depths (i.e., 0-5 cm, 5-15 cm, 15-30 cm, 30-60 cm, 60-100 cm, and 100-200 cm) derived from the two ensemble models (i.e., the hierarchical multi-model ...

SOIL HYDRAULIC PROPERTIES OF A CHROMIC LUVISOL IN KATUMANI, KENYA

Tropical and Subtropical Agroecosystems, 2022
Background: Soil hydraulic parameters in non-saturated conditions are crucial for explaining soil water dynamics in the field. It is therefore necessary to understand the link between soil water potential and hydraulic conductivity in the soil in order ...

PHYSIOLOGICAL REACTIONS AND INITIAL GROWTH OF TUXPEÑO CORN WITH VERMICOMPOST AND IRRIGATION SUSPENSION

Tropical and Subtropical Agroecosystems, 2021
Background: The water deficit in the early stages of corn cultivation determines the survival of the seedlings and the establishment of the crop, so it is desirable that the soil can conserve available moisture for long periods of time.

Irrigation Scheduling Based on Wireless Sensors Output and Soil-Water Characteristic Curve in Two Soils

Sensors, 2020
Data-driven irrigation planning can optimize crop yield and reduce adverse impacts on surface and ground water quality. We evaluated an irrigation scheduling strategy based on soil matric potentials recorded by wireless Watermark (WM) sensors installed ...

Plant-available soil water capacity: estimation methods and implications

Revista Brasileira de Ciência do Solo, 2014
The plant-available water capacity of the soil is defined as the water content between field capacity and wilting point, and has wide practical application in planning the land use.

Crop Response to Combined Availability of Soil Water and Its Salinity Level: Theory, Experiments and Validation on Golf Courses

Agronomy, 2021
The phenomenological expression showing crop yield to be directly dependent on water deficiency, under saline conditions, has encouraged a continued focus on salinity as a viable approach to increase crop yields.

Sodium and potassium allocation under drought stress in Atlas mastic tree (Pistacia atlantica subsp. mutica)

iForest - Biogeosciences and Forestry, 2013
Sodium and potassium ions have crucial roles in drought tolerant mechanisms of plants. In a pot experiment, seedlings of Pistacia atlantica subsp. mutica were cultivated in a silty clay soil (Kex=21 mg/l, Naex=143 mg/l) and exposed to different levels of

A relook into plant wilting: observational evidence based on unsaturated soil–plant-photosynthesis interaction

Scientific Reports, 2020
Permanent wilting point (PWP) is generally used to ascertain plant resistance against abiotic drought stress and designated as the soil water content (θ) corresponding to soil suction (ψ) at 1500 kPa obtained from the soil water retention curve ...

Development and Evaluation of Pedotransfer Functions to Estimate Soil Moisture Content at Field Capacity and Permanent Wilting Point for South African Soils

, 2021
This study was undertaken to develop new pedotransfer functions (PTFs) for the estimation of soil moisture content at field capacity (FC, at −33 kPa) and permanent wilting point (PWP, at −1500 kPa) for South African soils based on easily measurable soil ...
