The present study, was aimed to evaluate the use of new sustainable and integrate agricultural practices, alternatively to the conventional and unsustainable use of mineral fertilizers and pesticides, developing new technologies able to understand how these interact with plants metabolism. Specifically, were tested bio-fertilizers based on the use of recycling products like composts, alone or in combination with plant bio-stimulants like microorganisms and humic substances. Such bio-effectros, frequently used in the organic farming, not only ensures food safety and increases soil biodiversity but are considered totally eco-sustainable. The comprehension of rhizospheric micro-bio-humeome interactions and the effects on plants metabolome was studied by Metabolomics through the use of advanced analytical techniques, like gas-chromatography coupled with mass spectrometry (GC-MS) and Nuclear Magnetic Resonance spectroscopy (NMR). The results underline a positive effects on plants, exerted by the combined use of bio-fertilizers and bio-stimulants, suggesting therefore, their use as valuable alternative to the conventional agricultural practices able to promote the environmental sustainability and production of healthy foods maintaining crop productivity. Additionally, in order to better understand witch molecular class of compound play a specific role in the micro-bio-humeome interaction, the Humeomics approach applied directly on materials enrich of HS, was firstly evaluated, representing a preliminary experiment with the future aim to apply this technique also on materials containing humo-like substances such as compost from different sources. The employment of analytical approach such as Metabolomics and Humeomics for understand the rhizospheric micro-bio-humeome interaction, appear necessary in order to formulate in the future, tailored prepared with specific bio-stimulats actions as a function of different crops and soils characteristics.
