“…The zeolite-bearing sample comes from a thick deposit of volcanoclastic products close to Sorano (Grosseto, IT) having chabazite (68.5 ± 0.9%) and phillipsite (1.8 ± 0.4%) as the main zeolites, intertwined with a K-feldspar (9.7 ± 0.7%), mixed with volcanic glass (11.2 ± 1.0%) (Malferrari et al, 2013). The main utilization of these materials has been as dimension stones in the building industry; currently, they are also employed in animal farming and in agriculture (De'Gennaro and Langella, 1996) due to their easy availability, very low cost and their high-grade zeolites leading to a CECs of 2.17 meq/g (Malferrari et al, 2013).…”

“…The AM was divided in two plots of 50 cm each: in the unamended plot (Unamended) the whole soil profile was made of the unamended soil collected from the ZeoLIFE filed site while in the zeolite amended plot (Zeolite) the top 10 cm is a mixture of unamended soil and natural zeolites (Malferrari et al, 2013) having the sedimentological characteristics reported in Table 1 for the amended soil and the rest of the soil profile is made of unamended soil (Fig. 1).…”

“…The first two components gave the most useful information, accounting for an observed variance of 36% for F1 and 20.4% for F2. [8,37] SiO 2 and Na 2 O mainly correspond to the silty and sandy sediment fraction and suggest the presence of alkali feldspar and quartz in the coarser grain size. F2 shows positive loadings for Ce, Pb, Nb, Sc and negative loadings for the MnO.…”

Wavelength dispersive X-Ray f luorescence analysis, coupled with multivariate statistics, has been used to characterise the alluvial soils of the easternmost Po Plain area. Coarse to f ine sediments, which can be related to various depositional environments (paleochannels, interf luvial areas, brackish marsh interdistributary bays and littoral dunes), have been taken into consideration. Through the use of an extensive analytical database and the principal component analysis in combination with factorial analysis, a soil classif ication method is proposed, which can also help to constrain the depositional environment of the alluvial sediments. This methodology was subsequently validated using other wavelength dispersive X-Ray f luorescence analyses of soils with different provenance and historical bricks made with alluvial deposits similar to those already studied. By relating the principal component analysis in combination with factorial analysis factors, we therefore provide a useful tool to integrate the classical and well-established classif ication of alluvial deposits based on f ield observation and grain size investigations.

“…Zeolitites are rocks containing more than 50% of zeolites [6], hydrated minerals capable of binding NH 4 + from solutions in their extra-framework sites, preventing NH 4 + leaching by rainfalls and/or irrigation. In this way, zeolitites can increase nitrogen use efficiency (NUE) and behave as slow-releasing fertilizers, resulting in a more sustainable agriculture, where the amount of fertilizers can be decreased without lowering the production yield [6][7][8][9][10][11][12]. Due to their physic-chemical characteristics, zeolitites can be used as soil conditioners, carriers of fertilizers, antibacterial agents, insecticides, pesticides, as enhancer of soil biological activity and additional reducer of the Sodium Adsorption Ratio (SAR) index [13][14][15][16][17][18][19].…”

The use of rocks containing high amounts of natural zeolites (zeolitites) as soil amendment has been found as a valuable method for increasing agriculture sustainability. However, the potentialities and the effects of zeolitites on the biogeochemical cycles of nitrogen (N) and carbon (C) have still not been clearly addressed in the literature. The objective of this study was therefore to investigate the N and C pools and 15 N distribution in an agricultural soil amended with both natural and NH 4 + -enriched zeolitites with the aim of understanding their effects on the soil-plant system, during sorghum cultivation, under fertilization reductions. Zeolitites were applied to an agricultural soil both at natural state (5 and 15 kg m −2 ) and in an enriched state with NH 4 + ions from pig slurry (7 kg m −2 ). Both zeolitites at natural and enriched state increased soil cation exchange capacity and affected microbial biomass, causing an initial decrease of microbial C and N and then a possible increase of fungal population. N-NO 3 − content was lower in natural zeolitite treatments, that lead to a lower NO 3 − availability for denitrifying bacteria. Zeolitites slightly affected the fixed N-NH 4 + pool. δ 15 N turnover indicated that N from NH 4 + -enriched zeolitites remained in the soil until the growing season and that fertilizers partially substituted the fixed pool. Leaf δ 15 N content indicated that plants assimilated N from NH 4 + -enriched zeolitites and evidenced a higher fertilization recovery in natural zeolitite treatments. Organic C tended to be higher in all zeolitite treatment rhizospheres. In soils amended with zeolitites at natural state (at both application rates) sorghum yield was similar (+3.7%) to that obtained in the control while it was higher (+13.9%) in the plot amended with NH 4 + -enriched zeolitites.
