The effects of effluent from Thessaloniki, the second most populated Greek city, reclaimed either by activated sludge or by stabilization ponds, were studied on field-grown corn. The experimental layout was that of a split- plot design with six replications, three water qualities and two irrigation...

The results of a research study about the groundwater quality in western Thessaly, that took place during the period 2001-2002, are presented in this paper. The study included two samplings during May and August of 2002. In May the water table is at high level while at the end of the summer the...

This study was conducted to evaluate the surface and subsurface drip irrigation (SDI) application effects on sugar beet crop performance, under two levels (100% and 80%) of water application depth. The experimental design was a split plot with four replications. Laterals were set every second crop...

An experiment was conducted in a greenhouse located in Agrinion, Greece, in order to study the effect of the treated municipal wastewater (TMWW) on the soil heavy metal interactions, in comparison to ordinary well irrigation water, denoted as control. The ultimate aim was the establishment of sound...

Furrow irrigation is used for row crops. S.C.S., based on a great number of field experiments, under different circumstances and soil families, has developed design equations for furrow irrigation. These equations have been used for steady flow rate or for flow rate with one reduction when the water...

The main objective of this work is to apply the hedonic pricing method using the methodology of spatial econometrics in order to assess the economic value of irrigation water, as one of the individual attributes of the value of agricultural land parcels. Most of the agricultural land’s value...

Arsenic is an ubiquitous and highly toxic metalloid widely distributed in the environment through both natural and anthropogenic pathways (Liu et al., 2004) and its presence in food composites is a matter of concerns to the well being of both humans and animals. In fact, As has been recently found...

Various pollutants (e.g. boron and hexavalent chromium) are introduced into the aquatic environment from a variety of industrial operations causing damages to environment and affecting human health. Boron in irrigation water is of particular interest because it can have beneficial or toxic effect on...

Water volume consumed for crop irrigation at the plain of Thessaloniki – northern Greece, was estimated and compared against the volume reported by the General Land Reclamation Organisation (G.L.R.O.) of Thessaloniki – Lagada. For the estimation of net crop water requirements, apart from crop...

The main issue discussed in the paper is the application of qualitative analysis techniques when short data samples are available at the initial stage of experiments carried out to study behaviors of agricultural plant species under different environmental conditions. The proposed techniques are...

The use of phosphate slime or phosphate water in a Mediterranean region (Gafsa, Tunisia) was investigated through hydrologic modeling. The simulations were made using the Hydrus 1D software package for a typical soil in the area of Gafsa (Tunisia). Two main applications were examined: mixing the...

The present research analyzes the behavior of Agia Varvara aquifer in Drama, Greece. A comprehensive and complete simulation-management combination model is applied, capable of calculating the water mass balance of the aquifer and defining the optimal management solution. In order to simulate the...

The Plastiras dam was constructed in the late 1950s mainly for electric power production, but it has also partially covered irrigation needs and water supply of the plain of Thessaly. Later, the site has been designated as an environment conservation zone because of ecological and landscape values...

The decrease of available water resources, the water quality degradation as well as the rapid increase of population combined with the growth of human activities, impose today the development of a science that concerns the Management of Water Resources. Lake Volvi faces a lot of problems, the most...

Agriculture is an economic activity that contributes significantly to the gross national product of a country, securing at the same time the viability of the rural sector and the social coherence. On the other hand, it can generate an environmental externality, especially concerning water resources...

Greece is a typical Southern European country in which the agricultural sector is the major consumer of water, a fact that has potential impacts on the water resources efficient allocation and management. The record-high percentage of the agricultural water use at the national level, together with a...

The podzolic soils of the Kola Peninsula, Russia, have in localised areas been highly contaminated with copper and nickel from smelting activities. Migration and retention of these metals were investigated in undisturbed soil columns irrigated with simulated background and polluted precipitation in...

The direct assessment of denitrification suffers from a number of problems. A mass balance model is simple and widely accepted to calculate nitrogen (N) loss as a denitrification component. The objective of study was to estimate the potential N loss a denitrification from a tropical paddy in the...
