To evaluate the performances of a controlled drainage system in optimizing water use and reducing nutrient losses from agricultural fields, an experimental facility was set up in north-eastern Italy in 1996. Water table management was tested in combination with surface (open ditches) and subsurface (pipe) drainage systems. Data were collected from 2007 to 2013 on: water table depth, drained volumes, nitrogen and phosphorus concentrations in groundwater and in drainage water. Nitrogen in groundwater showed higher concentrations when controlled drainage was combined with open ditches system, with a median of 13.43 mg L−1 for NO3-N and 18.68 mg L−1 for total N. Drainage water showed an opposite trend: subsurface pipes with free drainage provided highest concentrations due to extensive leaching (a median of 20.7 mg L−1 for NO3-N and 24.0 mg L−1 for total N). Phosphorus concentrations showed notable differences in drainage water, with higher values in the controlled drainage – open ditches system due to surface runoff (a median of 0.190 mg L−1 for PO4-P and 0.536 mg L−1 for total P). In general, the most hazardous period for surface water pollution was autumn-winter, due to rainy weather and fertilizer application on bare soil. Overall, water table management reduced total water discharge by 81% compared to free drainage. On average, with controlled drainage annual nitrogen losses were lowered by 92% (from 29 to 2 kg NO3-N ha−1) and annual phosphorus losses by 65% (from 0.14 to 0.05 kg PO-4P ha−1). Free drainage with subsurface pipe was the worst combination from the environmental point of view: annual nitrogen and phosphorus losses were 46 kg NO3-N ha−1 and 0.10 kg PO4-P ha−1 respectively. Water table management clearly proved to be a reliable tool to improve both water usage and quality.

Agronomy, doi: 10.3390/agronomy8020023
In the Mediterranean arid and semi-arid regions, large amounts of low quality waters could be used for crop irrigation, but the adoption of articulated classifications with too rigid quality limits can often reduce the recoverable quantities of water and make the monitoring of water quality too much expensive. Therefore, an evaluation of irrigation water quality based on only a few crucial parameters, which consider the crop species to be irrigated and the type of irrigation system and management adopted, can be an easy and flexible method for maximizing the reuse of wastewater and low-quality water for agricultural purposes. In this view, an irrigation water quality tool (IWQT) was developed to support farmers of arid and semi-arid regions on evaluating the use of low quality water for crop irrigation. The most significant and cheapest parameters of irrigation water quality were identified and clustered in three quality classes according to their effects on crop yield and soil fertility (agronomic quality indicators), human health (hygiene and health quality indicators), and irrigation systems (management quality indicators). According to IWQT parameters, a tool reporting a series of recommendations, including water treatment types, was implemented to guide farmers on the use of low quality irrigation water.

Agronomy, doi: 10.3390/agronomy8010008
The aims of this study were to evaluate: (1) the effect of sodium chloride (NaCl) and mannitol at different osmotic pressures on the germination of three proso millet (Panicum miliaceum L.) genotypes (VIR 9181, Unikum, and Kinelskoje) under controlled laboratory conditions; and (2) the effects of irrigation water salinity, maximum crop evapotranspiration (ETm) restitution regimes, and arbuscular mycorrhizal fungi (AMF) inoculation on forage production in a marginal Mediterranean soil for the genotypes that showed the highest and lowest seed germination. In the laboratory experiment, the Unikum genotype showed the highest seed germination (95.1%), whereas the lowest was found for Kinelskoje (80.4%). Regardless of the osmoticum type, germination was significantly reduced by osmotic pressure increases. Unikum showed a higher fresh biomass yield (FBY) (620.4 ± 126.3 g m−2) than Kinelskoje (340.0 ± 73.5 g m−2). AMF inoculation did not influence FBY under salt conditions, while in the absence of salt conditions it significantly increased the Unikum FBY (+50.7%) as compared to the uninoculated treatment (552.5 ± 269 g m−2). The 25% ETm significantly reduced FBY in both genotypes (−86.2% and −84.1% for Unikum and Kinelskoje, respectively) sd compared to the 100% ETm treatments (1090.3 ± 49.7 g m−2 in Unikum and 587 ± 72.2 g m−2 in Kinelskoje). The obtained results give novel information about proso millet forage production in low-input agriculture in marginal semi-arid Mediterranean land.
Article 1 Read 0 Citations Life cycle assessment of a micro aquaponic system for educational purposes built using recovered material Published: 01 January 2018
Journal of Cleaner Production, doi: 10.1016/j.jclepro.2017.11.097
Aquaponics is not only a forward-looking technology but it has also been proposed as a tool for teaching natural sciences at all school levels, from primary school to university. Life cycle assessment (LCA) has become a widely accepted method of evaluating the environmental impact of products and services. In this context, the aims of this paper were:1) to create a low-price AP system for possible use as didactic tool using recovered material; 2) to evaluate the environmental impact of a micro AP model (1.5 m2) through LCA analysis; 3) to verify whether this micro AP model is representative of full-scale AP systems (>50 m2) in terms of water quality and water consumption. Both, the water quality and the average daily water consumption of our system were in line with data reported in literature for larger aquaponics. LCA shows that materials and energy flows linked to the system management practices and energy consumption principally contribute to environmental impacts. The cumulative annual energy demand of micro aquaponic system was 1040.5 kWh; assuming that this system was built for a class of 25 students, the energy consumption of the learning activity using the proposed micro aquaponic system would be 41.6 kWh student−1 year−1. The results showed that the micro aquaponic system reliably mimics a full-scale unit and that it is a teaching tool with a relatively low environmental impact.
