Open AccessPre- and post-harvest evapotranspiration, carbon exchange and water use efficiency of a mature peach orchard in semi-arid climate
Better knowledge of the evapotranspiration and carbon exchange of fruit trees is needed to optimize the trade-off between water use and carbon assimilation and to better understand the role of agriculture in t...

Almond responses to a single season of severe irrigation water restrictions
A substantial area of the new almond plantations in Spain is under irrigation, but due to recurring severe droughts, the irrigation water allocation for agriculture can be drastically reduced eventually. This ...

Long-term almond yield response to deficit irrigation
A substantial area of the new almond plantations in Spain is under irrigation but because of water scarcity, deficit irrigation (DI) strategies have to be adopted. This study assesses the long-term sustainabil...

Water requirements of mature almond trees in response to atmospheric demand
Accurate methods to determine irrigation requirements are necessary for the efficient use of water in agriculture. We conducted measurements of transpiration (T) of one almond tree placed in a large weighing lysi...

Yield response of almond trees to transpiration deficits
Irrigation optimization under limited water supply requires knowledge of the relation between consumptive use and production. The recent expansion of almond production is highly dependent on irrigation which m...

Analysing the combined effect of wetted area and irrigation volume on olive tree transpiration using a SPAC model with a multi-compartment soil solution
In this paper, we analyse the combined effect of wetted area and irrigation volume and its impact on olive tree transpiration (E p) after validating a multi-compartment SPAC model in a dri...

The Components of Evapotranspiration
Evapotranspiration is the sum of evaporation from the soil surface and the plant surfaces, and transpiration. The evaporation from the soil in agronomy follows a two-stage process depending if the soil surface...

Chapter
Wind and Turbulent Transport
The flow of wind over crop canopies causes a transfer of momentum from the air to the canopy that generates turbulence which enhances the exchange of matter and energy between the atmosphere and crops. Turbule...

Chapter
Soil Temperature and Soil Heat Flux
The soil temperature regime depends on its thermal properties (specific heat, thermal conductivity, thermal diffusivity and thermal admittance). The main factors affecting the thermal regime are water content,...

Chapter
Air Temperature and Humidity
Air temperature shows unstable profiles during the day and stable profiles during the night. Therefore, canopy temperature is generally higher than that of the air during the day and lower during the night. He...

Chapter
The Energy Balance
The main components of the energy balance are net radiation, latent heat flux (LE), sensible heat flux (H) and soil heat flux (G). These can be manipulated through changes in net radiation, LE, H or G. The rel...

Calculation of Evapotranspiration and Crop Water Requirements
Reference ET (ET0) is defined as the ET of short grass with full soil cover, and an unlimited supply of water and nutrients. In the absence of water deficit, the ET of any crop may be calculated as the product Kc

Manipulating the Crop Environment
Windbreaks are structures that reduce wind speed and may affect turbulence in the protected zone. The maximum efficiency is obtained with windbreaks of medium porosity that reduce wind speed up to a distance 2...

Using sap flow measurements to estimate net assimilation in olive trees under different irrigation regimes
The measurement of bulk net assimilation (A) in fruit tree species is hindered by the need for sophisticated and complex instrumentation. The aim of this study is to present a simple alternative for estimating A ...

Transpiration of young almond trees in relation to intercepted radiation
Increased water scarcity demands more efficient use of water in the agricultural sector which is the primary consumer of water. Precise determination of irrigation requirements based on specific crop parameter...
