“…Concerning the ZT used as adsorption media, the chosen material was delivered by an Italian company and comes from a quarry located in central Italy (42 • 41'20.65" N, 11 • 44'26.29" E, Sorano, Grosseto), the same exploited by [24,26,30,37]. The quarried rock is a thick zeolitized pyroclastic deposits belonging to the Sorano formation, a unit, which is part of the lithic yellow tuff erupted during quaternary by the latera volcanic complex [38].…”

“…Other forms of pre-exchanged zeolites have been found to increase adsorption performances, such as H-exchanged forms [22]. The use of different kinds of natural and pre-exchanged ZTs as a soil amendment has been studied extensively in terms of modification of the soil physic-chemical characteristics, reduced N leaching, increased N use Water 2020, 12, 310 3 of 20 efficiency, water use efficiency, and crop yield [23][24][25][26][27][28][29][30][31]. Zeolites mitigation potential concerning some greenhouse gasses (like CO 2 and N 2 O) and other harmful gasses like NO x and, especially NH 3 , has also been addressed in several studies [32][33][34][35][36].…”

Notwithstanding the widespread use of natural and pre-exchanged zeolites for zootechnical effluent treatment, little attention has been dedicated to the variation in the chemical composition of the treated slurries, besides the effects on their NH4+ content. This paper aimed at elucidating the compositional variations in terms of major and trace elements of a raw pig-slurry (PS) after three sequential treatment cycles (TC) with three different grain sizes of natural and Na-exchanged zeolite-rich volcanic tuffs (natural ZTs and NaZTs). A series of laboratory batch experiments revealed that all ZTs had profoundly influenced the final PS chemical composition. As expected, the NaZTs were more efficient in terms of NH4+ removal than the natural ZTs, reaching almost 60% reduction of the initial content after three TCs. A parallel effect of this efficient removal was the remarkable increase in Na+. The Na-forms of ZTs led also to stronger competition with K+ ions, resulting in adsorption of this macronutrient and hence in a reduction of the fertilization value of the PS. In terms of heavy metals and other trace elements, all the treatments with ZTs had significantly increased the Li, Ba, Rb, Sr, Ga, and U content in the PS.

“…Both bulk and rhizosphere soils in the 7CZ parcel showed higher exchangeable Na + with respect to the other treatments, likely because of the NEZ enrichment process with pig slurry. As it is known, NH 4 + -enriched zeolites can act as slow-released fertilizer [37][38][39] and in our experiment this behavior was clarified by the isotopic signature of the TN pool during the agricultural management. The δ 15 N increase of TN pool in 7CZ with respect to that found in the other treatments is in fact due to the N isotopic signature of the pig slurry contained into the NEZ.…”

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.

“…The NH 4 + and K + losses from soils amended with zeolite were less than those with chemical fertilizers. Chabazite was more effective than CLP at preventing NH 4 + loss during leaching, whereas reduction of K + loss was similar for both zeolites (Eslami et al, 2018). The influence of zeolite application was investigated under rainfall simulation to control for the effects of freeze-thaw on basic hydrological variables such as runoff production and soil loss.…”

Iran has significant deposits of high-purity natural zeolites. Many Iranian scholars conduct scientific research on porous materials, from natural and synthetic zeolites to metal organic framework materials. Iranian zeolite deposits and associated research are reviewed here. Various industrial applications of natural zeolites, from agriculture to animal husbandry to the construction industry and beyond are discussed here.
