The interaction of organic carbon (OC) with clay minerals and amorphous iron and aluminum oxides, especially in the finest soil fractions (<20 μm), represents a good method for its stabilization, and different tillage practices can improve or reduce the persistence of OC in soils. This study investigates the effects of conventional (CT) and no (NT) tillage and soil depth (0–30, 30–60, and 60–90 cm) on the soil organic carbon (SOC) in four soil size fractions and its interactions with clay minerals and amorphous oxides. To identify the mineralogical composition of the four soil size fractions isolated from each soil, the X-ray powder diffraction (XRPD) technique was used with near infrared (NIR) spectroscopy, while the X-ray fluorescence (XRF) technique was used to determine the chemical composition of soil fractions. The higher OC content found in the finest soil fraction is related to its higher content of clay minerals and amorphous oxides. The SOC content is similar among CT and NT treatments as well as the mineralogical composition and the amount of amorphous oxides, suggesting that more than ten years of different tillage did not influence those parameters.

The interaction of organic matter with the finest soil fractions (250 μm) is highest in the upper soil layer, while the finest fraction is in the deepest one. The greatest OC content is observed in the topsoil layer and in the finest soil fraction. DRIFT analysis suggests that organic components are more present in the finest fraction, calcite is mainly localized in the coarse fraction, quartz is in micro-aggregates and 53–20 μm fraction, and clay minerals are in the finest fraction.

The increasing food demand encourages the overuse of agricultural lands and natural resources that often is not economic, social and environmentally sustainable. This overuse can lead to the soil sickness, which causes the decline of the soil fertility through the development of soil‐borne diseases, the depletion of nutrients and the loss of soil organic matter. Addition of residual biomasses is a good agricultural practice for improving soil properties and enhancing crop production, in the framework of a sustainable development. The study was performed in a two years field experiment using olive pomace residues (OPR), composts from municipal solid wastes (CMW), spent mushroom compost (SMC), and livestock manures based compost (BRX) for the fertilization of the potato crop. The aim of the study was to test the impact of different biomasses available in Apulia region, Italy, on soil fertility and potato growth. The application of BRX showed the highest potato yield in both seasons while OPR, CMW, and SMC significantly increased soil total nitrogen and organic carbon compared to BRX and un‐amended plots (CON). All treatments, except SMC, reduced the soil exchangeable K content, therefore, the application of BRX, OPR and CMW should include the use of K based fertilizer to balance the high crop demand of K. Finally, SMC appeared the best compromise for managing soil fertility and obtaining high potato yield.

Four hundred hectares of the inland and hilly part of Apulia Region (Southern Italy) were contaminated by using low-quality composts for many years. That territory now belongs to a national park and needs a sustainable soil restoration. Therefore, a greenhouse experiment was carried out to test the phytoremediation potential of the frugal Helichrysum italicum (Roth) Don, alone and mycorrhized by Septoglomus viscosum. The aims of the research were (a) to test if the H. italicum can reduce the soil content of Cd, Co, Cr, Cu, Ni, Pb, and Zn; (b) to identify in which part of the plant those metals are mainly accumulated; (c) to check the role of S. viscosum in promoting the plant growth and the soil phytoremediation. The results showed better plant growth in contaminated soils in comparison to control soils, regardless of the presence of mycorrhiza, probably due to the better soil fertility parameters in contaminated soils. In addition, non-mycorrhized plants from contaminated soil accumulated greater amounts of heavy metals, especially Cr, Cu, Pb, and Zn, in their root system. According to the translocation and bioconcentration factors, the mechanism by which H. italicum incorporated heavy metals was ascribable to a phytostabilization process. In contrast, the application of mycorrhiza in the contaminated soil reduced the uptake of heavy metals by the roots, possibly through an exclusion mechanism, reducing the phytoremediation potential of H. italicum.
