Analysis of hydrochemical time series
(Corresponding) Kolarec B., Žeravica A.
Topic:
Soil and groundwater contamination and remediation
Agricultural activity of spreading fertilizers may, in case they are washed away to an aquifer, result in a groundwater contamination. There was a research conducted in Croatia on the lower part of the Danube-Sava canal which is occupied by extensive agricultural production to measure the...Read more

Modeling the spatial evolution of nitrogen pollution in groundwater and the amount of nitrogen leached under potato crops in the Khemis Miliana Plain
(Corresponding) Richa A., Douaoui A., Djezzar M.
Topic:
Soil and groundwater contamination and remediation
The maximum concentration of nitrates in drinking water admitted by the World Health Organization is 50 mg nitrate per liter of water. Europe recommends a standard content of 25 mg NO3- / l according to the interdisciplinary research program on the environment (2009).
The present work quantifies...Read more
UN(K)NOWN Project: Development of Anammox microbial inocula to improve nitrogen removal efficiency in wastewater treatment
(Corresponding) Ribeiro H., Machado A., Costa-Dias S., Wijaya I., Salgado P., Bordalo A., Teixeira C.
Topic:
Wastewater treatment
The discovery of anaerobic ammonium oxidation (anammox) revealed the existence of a shortcut in the classic nitrogen cycle where ammonium is converted directly to dinitrogen gas. Anammox process can be used to develop more cost and energy-efficient sustainable nitrogen removal systems comparing to...Read more
Start-up of the nitrogen removal process in an anaerobic up-flow reactor inoculated with aeration tank sludge
Wijaya I., (Corresponding) Ribeiro H., Soedjono E., Slamet ., Teixeira C., Bordalo A.
Topic:
Wastewater treatment
Anaerobic ammonium oxidation (anammox) has been considered a promisingly alternative to traditional nitrification/denitrification to remove nitrogen in an autotrophic process, without using an external carbon source, requiring low energy consumption and sludge production. The start-up of the...Read more
Impact of nitrogen fertilization on nodulation and symbiotic efficiency of indigenous Bradyrhizobium japonicum strains
(Corresponding) Sikora S., Abrlic J., Rajnović I., Kajic S.
Topic:
Agroforestry, forest and agricultural sustainability
Nitrogen fixation is a beneficial microbial process that greatly contribute to sustainable agricultural production and environment protection. Soil bacteria, collectively named rhizobia, are characterized by their unique ability to induce the formation of root nodules in which they convert...Read more
The effect of intercrop on soil properties of an agroforestry system in Kea -Greece
(Corresponding) Pantera A., Papadopoulos A., Fotiadis G., Kapsalis D., Pinelopi P., Papaspyropoulos K.
Topic:
Agroforestry, forest and agricultural sustainability
Valonia oak is the most widespread tree species found in the Aegean island of Kea - Cyclades. It forms traditional agroforestry systems since intensive agriculture is not easily practiced in the island due to the xerothermic climate and the rough terrain with steep slopes. This system has...Read more
Effects of nitrogen fertilizer on photosynthetic light energy transfer and use in hybrid fescue under drought stress
(Corresponding) Januškaitienė I., Dikšaitytė A., Sujetovienė G., Žaltauskaitė J., Kacienė G., Miškelytė D., Juknys R.
Topic:
Ecology, environmental change and management
The aim of this study was to investigate the response of chlorophyll a fluorescence parameters of hybrid fescue (× Festulolium loliaceum (Huds.) P. Fourn.) under partly regulated environment and drought stress effect. The results showed that the increasing nitrogen content increased the values of...Read more
Degradation of textile dyes in water by gas-liquid NSP-DBD plasma
MEROPOULIS S., (Corresponding) AGGELOPOULOS C.
Topic:
Advanced oxidation processes
Textile dyes represent some of the most complicated environmental pollutants due to their variety and complex structure. Cold atmospheric plasma (CAP) is regarded as a highly competitive advanced oxidation process towards the removal of organic pollutants from wastewater. In this study, a gas-...Read more
Forage crops nitrogen use efficiency changes under drought conditions
(Corresponding) Žaltauskaitė J., Dikšaitytė A., Miškelytė D., Sujetovienė G., Januškaitienė I., Kacienė G.
Topic:
Ecological effects of environmental change
Ensuring sustainable agriculture and food security is one of the biggest challenges under changing climate. The frequency and severity of droughts is increasing as a result of climate change. These extreme events may lead to decreased forage crop productivity and financial incomes. Forage crop...Read more

Nutrients recovery from anaerobic digestion effluent for the production of microalgae biomass
(Corresponding) Psachoulia P., Schortsianiti S., Dergiade I., Chatzidoukas C., Samaras P.
Topic:
Wastewater treatment
The efficient management of anaerobic digestion effluents (ADEs) from biogas plants has raised increasing environmental concerns, as a result of their high content in nutrients, mostly in the form of NH4- and PO4-. Their discharge to farmlands is restricted due to irrigation guidelines, while...Read more
