Aerogation: Crop root-zone aeration through subsurface drip irrigation system
(2014)Subsurface drip irrigation as a source that provides the water directly to the root zone develops a saturated wetted front in the rhizosphere, particularly when the irrigation is close to 100% of evapotranspiration. Long ... -
The effect of an intelligent surface drip irrigation method on sorghum biomass, energy and water savings
(2013)Over the last few decades, precipitation has decreased as a result of climate change. This change increases crop water requirements, while irrigation water is wasted because of improper irrigation scheduling. Soil moisture ... -
Effect of modern irrigation methods on growth and energy production of sweet sorghum (var. Keller) on a dry year in Central Greece
(2007)The subject of this project is to estimate the growth and productivity of sweet sorghum [Sorghum bicolor (L.)] var. Keller, under two different irrigation methods - the conventional surface drip method (two treatments) and ... -
Effects of treated municipal wastewater on the essential nutrients interactions in the plant of Brassica oleracea var. Italica
(2009)The effects of the treated municipal wastewater (TMWW) on the essential nutrients interactions in the various plant parts of Brassica oleracea var. Italica (Broccoli) was studied, in comparison to the fresh irrigation ... -
Estimation of unsaturated flow in layered soils with the finite control volume method
(2001)Water movement in unsaturated soil is described by Richards' equation, which is strongly nonlinear and cannot be solved analytically. For this reason numerical methods such as finite difference and finite element methods ... -
THE INFLUENCE OF DIFFERENT DRIP IRRIGATION LAYOUT DESIGNS ON SUGAR BEET YIELD AND THEIR CONTRIBUTION TO ENVIRONMENTAL SUSTAINABILITY
(2010)Drip irrigation may constitute a method for sustainable management of water resources and can contribute to environmental protection and sustainability. However, there is still limited information on the application of ... -
Laboratory experiments and estimation of cumulative infiltration and sorptivity
(2004)Soil water cumulative infiltration affects the environment by controlling the irrigation rate and consequently the water and pollutants movement through the ground. In order to study the cumulative infiltration in a sandy ... -
Land use changes and its impacts on water resources in Nile Delta region using remote sensing techniques
(2013)Sustainable water resources management plans depend on reliable monitoring of land use -land cover (LULC) changes. The use of the remote sensing techniques in LULC changes detection brings consistency and reliability to ... -
A New Analytical Model to Predict the Hydraulic Conductivity of Unsaturated Soils
(1996)A new analytical model is presented for the prediction of hydraulic conductivity. The new model is based on the Brutsaert characteristic curve psi(theta) and the Mualem integral relation. It is presented by a series expansion ... -
Simulation of soil water drainage in sandy soils, laid on a ceramic plate. Comparison with experimental data
(1998)In the present paper the simulation of water movement during vertical one dimensional drainage is presented. The study is referred to uniform sandy soil samples, laid on a ceramic plate of a very small saturation hydraulic ... -
Sorghum economics under different irrigation methods and water doses
(2009)In this study, an attempt has been made to evaluate the biomass production and the economic results of sorghum growing in Greece under surface and sub-surface drip irrigation and with three different amounts of irrigating ... -
Theoretical and Experimental Research of Cumulative Infiltration
(2013)The main object of this study is the comparative evaluation of Green & Ampt's (G & A) and Parlange's (P's) models and their ability to describe cumulative infiltration of water through various soil types. Three soil samples ... -
Water Drainage in Layered Soils. Laboratory Experiments and Numerical Simulation
(1997)Experimental results during first and second drainage in a vertical column of saturated layered soil were compared to those predicted from simulation. The sample was composed of a sandyloam soil overlying a fine sand. The ... -
WATER-SAVING BY IRRIGATING TWO VARIETIES OF SORGHUM (ENERGY PLANT) WITH TREATED MUNICIPAL WASTEWATER: A 3-YEARS STUDY IN CENTRAL GREECE
(2012)In the last few years, the problem of limited precipitations and, consequently, the lack of water along with the rapid climatic changes have been one of the main topics of discussion in environmental forums all over the ...
