Lysimeters in Vadose Zone Research

open access: yesVadose Zone Journal, 2018
Lysimeters are methodological experimental tools to study the water and matter fluxes in the vadose zone, as well as the environmental fate of chemicals. Lysimeters are available in various types.

An overview of the experimental research use of lysimeters

open access: yesEnvironmental & Socio-economic Studies, 2019
The lysimeter is most often defined as a box filled with soil with an intact structure for measuring the amount of infiltration and evapotranspiration in natural conditions.

Development, calibration and validation of weighing lysimeters for measurement of evapotranspiration of crops

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2019
The evapotranspiration process is critical to studies on the water balance and water demand of crops and can be determined by several methods. A widely-used method, despite its high installation costs, is weighing lysimeters, which consists of a box over

Evaluation of fast growing tree water use under different soil moisture regimes using wick lysimeters

open access: yesiForest - Biogeosciences and Forestry, 2013
The cultivation of fast growing trees has high potential for bioenergy production on marginal lands. Information about the water use efficiency in combination with the ecophysiological response to drought stress is still incomplete.

Large Variations in the Transpiration of Sorghum Canopies Under High Evaporative Demand Are Positively Related to Water Use Efficiency. [PDF]

open access: yesPlant Cell Environ
ABSTRACT Transpiration restriction under high vapour pressure deficit (VPD), measured indoors with individual plants, increases water use efficiency (WUE). However, VPD is not the only factor driving transpiration, individual plants in a field rapidly become a canopy, and reports on the transpiration restriction versus WUE are scant.

Measuring and Validating the Actual Evaporation and Soil Moisture Dynamic in Arid Regions under Unirrigated Land Using Smart Field Lysimeters and Numerical Modeling

open access: yesWater, 2022
Though forming a fundamental component of the water budget, soil evaporation is challenging to quantify in practice. Most water balance and soil moisture studies rely on pan evaporation or empirical relations to calculate evaporation, which is later used

Crop coefficients, growth rates and quality of cool-season turfgrasses [PDF]

open access: yes, 2015
Determination of crop coefficients (Kc), the ratio between actual (ETa) and reference evapotranspiration (ET0), is necessary to schedule irrigation. Our objective was to determine Kc, turf quality and growth rate under daily irrigation to field capacity (

Crop coefficient and water requirement of prickly pear in the Agreste region of Alagoas state, Brazil [PDF]

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2019
Prickly pear cultivation has played an important role in the Brazilian livestock farming, being used as forage for animals in the Northeast region, especially during the drying season, because it is an excellent source of water.

An expression for land surface water storage monitoring using a two-formation geological weighing lysimeter [PDF]

open access: yes, 2007
Field studies have demonstrated that ground surface rainfall accumulation can be detected at depth by synchronous increases in static confined groundwater pore pressures.
