This thesis has the main objective of studying the emissions of GHGs (CO2, CH4, and N2O) in different crop systems characterized by varying soil management practices. Five different soil management systems were analyzed as follows: conventional agriculture, continuous soil cover with cover crops, and conservation agriculture with two different levels of soil compaction, as well as bare soil. All cropping systems were managed under typical groundwater conditions (-120 cm) of the Veneto lowland region. The aim was to investigate and identify which system could contribute to reducing GHG emissions, nitrogen leaching, and influence biomass production, as well as determine whether different levels of soil compaction could alter these dynamics. This study is part of a project funded by the Veneto Region, which aims to study the impacts on water, soil, and air matrices resulting from the implementation of sustainable farming practices.
Questa tesi ha come obiettivo principale lo studio delle emissioni di gas climalteranti (CO2, CH4 e N2O) in sistemi colturali differenti caratterizzati da una differente gestione del suolo. Sono stati analizzati cinque sistemi differenti di gestione del suolo come segue: agricoltura convenzionale, copertura continuativa del suolo con cover crop, e agricoltura conservativa secondo due diversi livelli di compattamento del suolo, infine di suolo nudo. Tutti i sistemi colturali sono stati gestiti in condizioni di falda ipodermica (-120 cm) tipica del territorio della bassa pianura veneta. Lo scopo è stato quello di studiare e identificare quale sistema potesse contribuire a ridurre le emissioni di GHGs, la lisciviazione di azoto e influenzare la produzione di biomassa, nonché determinare qualora un diverso grado di compattazione potesse alterare queste dinamiche. Il presente studio si inserisce nell’ambito di un progetto finanziato dalla Regione Veneto, che ha come scopo lo studio degli impatti sulle matrici di acqua, suolo e aria derivanti dall’applicazione di pratiche colturali sostenibili.
