Sandy soils are widely distributed across the world. Due to the growing global population
and urbanization, these soils are increasingly used to provide food, feed, fiber, energy, and …

Abstract The FAO Irrigation and Drainage Paper No 56 on Crop Evapotranspiration has
been in publication for more than 15 years. The paper advanced the accuracy and …

Abstract This Manual of Practice (MOP) is a comprehensive reference to estimating the
water quantities needed for irrigation of crops based upon the physics of evaporation and …

One of the main problems confronting the world of the 21st Century is a shortage of water.
There is already severe scarcity in many regions of the world, causing tremendous problems …

The FAO-56 procedure for estimating the crop coefficient K c as a function of fraction of
ground cover and crop height has been formalized in this study using a density coefficient K …

Evapotranspiration (ET) calculation guidelines are based on the crop coefficient-reference
evapotranspiration method (Kc ETref). Equations for the ASCE-EWRI standardized Penman …

To achieve sustainable development and to ensure water availability in hydrological basins,
water managers need tools to determine the actual evapotranspiration (ET) on a large scale …

Irrigated agriculture produces about 40% of all food and fibre on about 16% of all cropped
land. As such, irrigated agriculture is a productive user of resources; both in terms of yield …

Evapotranspiration (ET), linking water, energy and carbon cycles, is frequently a major
component of the water balance for terrestrial ecosystems. The accurate estimation of water …

The main goal of this research was to evaluate the potential of the dual approach of FAO-56
for estimating actual crop evapotranspiration (AET) and its components (crop transpiration …
