Objectives

Improve  surface water quality with phytodepuration techniques in relation to the widespread pollutants of agricultural activity (nutrients and pesticides) at the farm and irrigation district level.
Possibility of  waste water reuse deriving from the processing  of the agri-food chains, in a "circular economy" process - evaluating the toxicity linked to the accumulation of salts, the presence of residues in the marketed agricultural products, the opportunity to use nitrate-laden waters to reduce nutritional intake with synthetic fertilizers.
Biological control strategies against Halyomorpha halys with low-impact techniques in phytodepuration systems

Objectives

Migliorare la qualità delle acque di superficie mediante fitodepurazione per ridurre gli inquinanti diffusi dell’attività agricola (nutrienti e pesticidi) a livello di azienda agricola e di distretto irriguo.
Riuso di acque reflue derivanti da processi di lavorazione di filiere agroalimentari, in un processo di economia circolare, valutando tossicità per accumulo di sali, presenza di residui nei prodotti agricoli, opportunità di utilizzare acque cariche di nitrati per ridurre gli apporti nutrizionali con concimi di sintesi.
Verifica della possibilità di applicare strategie di lotta biologica per il controllo della cimice asiatica con tecniche a basso impatto nei sistemi fitodepuranti

Activities

The capacity of a phytodepuration system at farm scale fed with drainage water coming from the farm’s fields will be evaluated, to purify nutrients and pesticides by setting up a modeling study on a real scale.
Study of a model for assessing the effectiveness of biological and integrated productions on the improvement surface waters quality of a drain-irrigation channel.
Verification of the irrigation reuse of wastewater of agro-industrial origin to evaluate possible phytotoxicity, organic nitrogen supply, water saving of traditional sources.
Biological fight for the control of Halyomorpha Halis with native antagonists and exotic species.

Activities

Uso di un sistema di fitodepurazione aziendale alimentato con acque di drenaggio proveniente dai terreni agricoli dell’azienda, per la depurazione di nutrienti e fitofarmaci. 
Studio di un modello di valutazione dell’efficacia delle produzioni biologiche e integrate sul miglioramento delle acque superficiali di un canale promiscuo (scolo-irrigazione).
Riuso irriguo di acque reflue di origine agroindustriale per valutarne eventuali fitotossicità, apporto di azoto organico, risparmio idrico di fonti tradizionali. 
Lotta biologica alla cimice asiatica con antagonisti autoctoni e specie esotiche.

Context

Climate change is increasingly involving water scarcity, with strong repercussions on the availability of water for irrigation. These drought phenomena are increasingly evident also in the ER Region, where the strong agricultural vocation makes it even more vulnerable to situations of water scarcity with a growing water deficit balance (-627 mm in 2017 compared to -495 mm, average of the period 2001-2015). This situation, together with the current levels of contamination of surface and underground water bodies, which classify them as being of poor quality, recommends diversifying supplies, focusing on phytodepuration to mitigate the impact of agricultural activity and resource reuse unconventional water, including the reuse of treated wastewater. Finally, the current state of knowledge on the effects of the agro-environmental measures of the RDP in contrasting the phenomena previously described, is derived from indirect sources: it therefore appears decisive to identify a territorial model that assigns a value to the indicators relating to contaminants, which comes from territorial monitoring of large surfaces. This Plan aims at enhancing, within the regional territory, the inter-farms and consortia wetlands, since they allow the reduction of polluting loads in the bodies receptors  of drainage and irrigation water to agricultural areas, improving their quality.
These areas also appear to be the natural habitat for the reproduction of Haliomorpha Halis and where it could therefore be possible to practice biological control carried out by native and possibly exotic antagonist insects. A chapter is dedicated to the re-use of water deriving from agro-industrial activities, realizing in practice an example of a circular economy.

1 Practice Abstracts

Quantification of residues of active principles of agrochemicals and nutrients in the drainage waters of the farm compared to the spread on crops of an extensive, horticultural and fruit farm; removal capacity of wetland systems and elimination times of herbicides, insecticides, fungicides and nutrients from surface waters

Phytodepuration techniques for improving the water quality of a mixed reclamation canal (irrigation and drainage), in compliance with the restrictive parameters required of those who practice biological farming.

A model for assessing the effectiveness of "Integrated Production and biological methods" measures, on the quality of water in territorial contexts where the drainage activity and the delivery of irrigation water to the farms overlap. Variation of the gross balance of nutrients (nitrogen and phosphorus) in the areas of intervention. Variation in the use of phytosanitary products classified by degree of toxicity by virtue of agri-environmental commitments, in the areas of intervention;

Tolerance thresholds for the use of wastewater according to the species considered, guidelines for farmers according to the quality of the waste water and crops. Estimate of the lower costs of wastewater treatment and disposal, and of water savings resulting from the lower use of surface water.

Reduction of Halyomorpha flights, inside the wetland and wooded areas, and inside the neighboring orchards, thanks to the use of antagonist insect and exotic species in the phytodepuration system

Quantificazione dei residui di principi attivi di agrofarmaci e nutrienti nelle acque di drenaggio aziendale rispetto al distribuito su colture di un’azienda a ordinamento estensivo, orticolo e frutticolo; capacità di rimozione dei sistemi fitodepuranti e tempi di abbattimento delle molecole di diserbanti, insetticidi, anticrittogamici e dei nutrienti dalle acque superficiali; 

Realizzazione di un modello per la valutazione dell’efficacia delle misure di “Produzione Integrata e metodi biologici”, sulla qualità delle acque in contesti territoriali in cui si sovrapponga l’attività di scolo e la consegna di acqua irrigua alle aziende agricole. Variazione dei Bilanci lordi dei nutrienti (azoto e fosforo) nelle aree di intervento. Variazione dell’uso dei prodotti fitosanitari classificati per grado di tossicità in virtù degli impegni agro-ambientali, nelle aree di intervento;

Tecniche di fitodepurazione per il miglioramento della qualità delle acque di un canale di bonifica promiscuo (irriguo e di scolo), in conformità ai parametri restrittivi richiesti a chi pratica agricoltura biologica. 

Soglie di tolleranza all’uso di acque reflue in funzione della specie considerata, predisposizione di linee guida ad uso dell’agricoltore in funzione della qualità del refluo e delle colture. Stima dei minori costi di smaltimento dei reflui, e del risparmio idrico conseguente al minor uso di acque superficiali.

Riduzione dei voli di Halyomorpha, sia dentro l’area umida e fasce boscate, che dentro ai frutteti limitrofi, grazie all’impiego mirato dentro al sistema fitodepurante di antagonisti autoctoni e specie esotiche
