Advancements of nanotechnologies in crop promotion and soil fertility: Benefits, life cycle assessment, and legislation policies
(2021)Increasing agricultural production has become one of the key components to bridge the gap between securing food resources and sustainable development goals (SDGs), namely, no poverty, zero hunger, preservation of natural ... -
Alteration of NO - 3, PO 3- 4 and SO 2- 4 Concentration on rose plants in response to greenhouse climate parameters and their concentration in the nutrient solution
(2011)The objective of this work was to quantify temporal changes of NO - 3, PO 3- 4 and SO 2- 4 concentration on leaves, shoots and roots of rose plants during a short growing period, in response to air temperature, light ... -
Assessment of nutrients and heavy metals in the surface sediments of the artificially lake water reservoir Karla, Thessaly, Greece
(2015)In this research, the sediment quality of the recently reconstructed Lake Karla (central Greece) was evaluated by monitoring the nutrient loadings and heavy metal concentrations in 16 sites during the initial period of the ... -
The bioactive profile of lettuce produced in a closed soilless system as configured by combinatorial effects of genotype and macrocation supply composition
(2020)The effect of cultivar and nutrient solution macrocation proportions (SK, SCa, SMg) on the bioactive content of hydroponically cultivated lettuce was evaluated on two lettuce cultivars (red and green-pigmented Salanova®) ... -
Comment on Muzzioli et al. Are Front-of-Pack Labels a Health Policy Tool? Nutrients 2022, 14, 771

Crop reflectance monitoring as a tool for water stress detection in greenhouses: A review
(2016)Multisensory platforms for remote sensing measurements offer the possibility to monitor in real-time the crop health status without affecting the crop and environmental conditions. The concept of the speaking plant approach, ... -
Development of an advanced embedded system for description of electrophysiological phenomena in ornamental plants by biosignals processing
(2011)Extracellular electrical signals that are produced from plants have different patterns depending on factors that may cause stress such as water deficiency, nutrient shortages, high salinity level in the root environment ... -
Effect of macronutrients and of anaerobic digestate on the heterotrophic cultivation of Chlorella vulgaris grown with glycerol
(2022)The aim of this work was to investigate the kinetics of the heterotrophic growth of Chlorella vulgaris as a means of producing bio-oil for biodiesel production. Glycerol was used as the sole organic carbon substrate. ... -
An empirical model to estimate nutrients concentration in controlled release fertilizers aqueous solutions
(2017)Controlled release fertilizers (CRFs) insure controlled release of nutrients due to their coating. The aim of this study was to investigate the effect of nutrient solution parameters as well as time on the evolution of ... -
Evaluation of various commodities for the development of the yellow mealworm, Tenebrio molitor
(2020)We evaluated the suitability of forty-four commodities (i.e., cereal flours and meals, non-flour, cereal commodities, legumes and various commodities of vegetative and animal origin) as oviposition and feeding substrates ... -
Fish welfare in aquaponic systems: Its relation to water quality with an emphasis on feed and faeces-A review
(2017)Aquaponics is the combination of aquaculture (fish) and hydroponic cultivation of plants. This review examines fish welfare in relation to rearing water quality, fish feed and fish waste and faeces to develop a sustainable ... -
Herbal plants- and rice straw-derived biochars reduced metal mobilization in fishpond sediments and improved their potential as fertilizers
(2022)Fishpond sediments are rich in organic carbon and nutrients; thus, they can be used as potential fertilizers and soil conditioners. However, sediments can be contaminated with toxic elements (TEs), which have to be immobilized ... -
'Insects as Food and Feed: If You Can't Beat Them, Eat Them!' - To the Magnificent Seven and Beyond
(2021)The objective of this special issue is to highlight the current state of research in the field of insects as food and feed, but also other aspects on the exploitation of insect farming. In this editorial, we make a short ... -
Integrated management of hydroponic wastewater for complete water recycle and cyanobacteria cultivation using an electric conductivity-based tool
(2022)This work presents an integrated management process for hydroponic wastewater (HWW) reuse, by developing an electric conductivity-based tool that calculates recycled nutrient solutions' enrichment requirements and indicates ... -
Investigation of factors affecting the trophic state of a shallow Mediterranean reconstructed lake
(2017)In this article, we focus on shallow sub-tropical lakes and study the factors that determine their trophic state and food web structure. We use the model PCLake to simulate lake nutrient dynamics and investigate key factors ... -
Mathematical modeling of trophic state and nutrient flows of Lake Karla using the PCLake model
(2015)In the present article, we simulate Lake Karla, an important natural ecosystem under restoration in Greece, operating also as a reservoir. The lake trophic state is characterized as hypertrophic with the expected negative ... -
A Meta-Epidemiological Study of Positive Results in Clinical Nutrition Research: The Good, the Bad and the Ugly of Statistically Significant Findings
(2022)Positive (statistically significant) findings are easily produced in nutrition research when specific aspects of the research design and analysis are not accounted for. To address this issue, recently, a pledge was made ... -
Nitrogen, Phosphorus, and Potassium Availability in Manure- and Sewage Sludge-Applied Soil
(2015)A field experiment with wheat (Triticum aestivum L.) was established over two growing seasons where farmyard manure and sewage sludge, along with conventional fertilizer, were added to soil. We found that ammonium N was ... -
