Abstract: I.Introduction - Increasing world population and limitation of land areas for agricultural uses have driven, from the last century, industrial investments towards the production of fertilisers, to improve crop yields and match human nutritional needs. However, the damages to soil ecosystems (properties and biodiversity) and the excessive use of these agrochemicals, both involved in intensive agricultural practices, have caused great impact on the environment and human health. As a consequence, stakeholders and governments have addressed their attention towards more environmentally friendly approaches (e.g. organic farming). Natural ecosystems have developed several strategies and mechanisms to deal with problems. Sometimes, the solutions are simple and involve the modification of the surrounding environment where plants grow (e.g. acidification), or the production of compounds for specific purposes (e.g. biopesticides). These solutions are quite easy to be reproduced and then have been promptly used by farmers and industries in the last decades. Oppositely, other natural approaches and mechanisms are quite complex and can involve, for example, the stimulation of beneficial organisms that suppress pests and pathogens by predation or the secretion of biocidal compounds [1]. Besides, beneficial organisms can also be employed to produce substances either stimulating plant growth or providing directly or indirectly nutrients to plants, or both [1]. Electrospinning is a powerful technology capable of producing fibres in the range of tens of nanometres to few micrometres that can be used to create 2D and 3D structures of fibrous scaffolds. The exceptional increase in the specific surface area, typical of nanofibrous fabrics, provides this technology enormous potential in creating materials with proper features for several applications, where a large interactive surface is required (medicine, environment, healthcare, textile, energy, etc.). Electrospinning can provide fabrics suitable for loading and releasing substances for specific purposes (e.g. nanomedicine), play appropriate activities (e.g. fuel cells), provide support for cell growth (e.g. wound healing), etc. [2,3]. II.Results - Our efforts were addressed to create electrospun nanofibrous scaffolds (Image 1A-D) suitable for the following purposes: i) providing nutrients to plants through the loading and release of siderophores to mobilise iron in soil and make it absorbable by plants; ii) delivering nutrients to plants by supporting the adhesion and growth of beneficial microorganisms (Image 1E) capable of mobilising phosphorus and/or iron in soil and their uptake by plants (Image 1F-G); iii) supporting the adhesion and growth of beneficial microorganisms capable of suppressing phytopathogens causing plant diseases; iv) loading and releasing enzymes degrading pesticides and organic xenobiotics in water and soil, thus reducing the negative impact on environment and human health; v) creating sensing platforms to detect plant diseases. Some of these scaffolds were tested in long-term tests to assess their possible employment as effective agricultural tools. III.References [1]. J. Dighton, J.A.
