Shoot water content and reference evapotranspiration for determination of crop evapotranspiration

African Crop Science Journal, 2017
Determination of water requirement for crops in resource limited areas is  challenging, yet worsened by the common assumption that all crop varieties within a species have similar water requirements. The objective of the study was to  indirectly determine crop evapotranspiration of soybean varieties, using reference evapotranspiration and shoot water ...

Multi-temporal evaluation of soil moisture and land surface temperature dynamics using in situ and satellite observations [PDF]

, 2016
Soil moisture (SM) is an important component of the Earth’s surface water balance and by extension the energy balance, regulating the land surface temperature (LST) and evapotranspiration (ET). Nowadays, there are two missions dedicated to monitoring the

Quantifying the Distribution of Evapotranspiration at PV and APV Sites Using Soil Moisture

AgriVoltaics Conference Proceedings
Solar panels affect the distribution of water and energy reaching the ground causing changes in soil moisture, evapotranspiration and percolation. In the context of Agri-Photovoltaics those changes influence plant growth and yield as well as irrigation ...

Reference evapotranspiration of screenhouse‐grown crops

Actas del III Workshop en Investigación Agroalimentaria. WiA 3.1
The reference evapotranspiration Eref was measured under three screenhouses and compared to outside Eref. The reduction with respect to outside Eref was quantified by means of two factors, rad and adv. rad was found to depend linearly on transmittance (), and adv on wind ratio (). A model was proposed for screenhouse Eref based on

Behaviour of carbon dioxide and water vapour flux densities from a disturbed raised peat bog [PDF]

, 2002
Measurements of carbon dioxide and water vapour flux densities were carried out for a disturbed raised peat bog in the north of the Netherlands during an 18 month continuous experiment. Tussock grass (sp. Molinea caerulae) mainly dominated the vegetation

GAIA: A New Formula for Reference Evapotranspiration

Atmosphere
Estimating evapotranspiration is crucial for irrigation and agricultural applications. Although the FAO-56 Penman–Monteith method is highly accurate under conditions of abundant data, its extensive requirements limit its practical application.

Heuristic methods applied in reference evapotranspiration modeling

Ciência e Agrotecnologia
The importance of the precise estimation of evapotranspiration is directly related to sustainable water usage. Since agriculture represents 70% of Brazil’s water consumption, adequate and efficient application of water may reduce the conflicts over the ...

Upscaling key ecosystem functions across the conterminous United States by a water-centric ecosystem model [PDF]

, 2011
We developed a water-centric monthly scale simulation model (WaSSI-C) by integrating empirical water and carbon flux measurements from the FLUXNET network and an existing water supply and demand accounting model (WaSSI).

Assessing Stormwater Nutrient and Heavy Metal Plant Uptake in an Experimental Bioretention Pond [PDF]

, 2018
With the purpose to study a solution based on Sustainable Urban Drainage Systems (SUDS) to reduce and treat stormwater runoff in urban areas, a bioretention pond (BP) was realized in the Agripolis campus of the University of Padova, Italy.
