“…The upper 2 m-thick layer of non-heated Andosols had the mineralogical composition typical for this soil type 27 , 36 and parent materials in the Valley of Geysers 32 , with predominant feldspars and smectite, frequent kaolinite, zeolites and occasional quartz, anatase, pyrite and goethite (Table S6 ). According to SEM and XRD data, the mineralogical and elemental composition changed insignificantly with depth, except for the appearance of newly formed opal and rare fragments of etched volcanic glass at a depth of more than 15 cm (Fig.…”

The picturesque and high conservation value thermal landscapes of the Valley of Geysers feature endothermal (heated by endogenous fluids) soils which support endangered and unique species. However, such soils have not been distinguished as a separate taxon within most classification systems. In this study, we described the soil morphology at macro-, meso- and micro-scales, chemistry, mineralogy and vegetation of these landscapes as they are affected by the steam-heated acid-sulfate waters. The studied catenary sequence from exothermal (non-heated) to endothermal soils was characterized by decreasing contents of soil organic carbon, sand fraction, essential nutrients (Ca, K, Mg, Mn and Si), increasing soil acidity, amounts of fine particle-size fractions and contents of trace elements (Al, As, Co, Cr, Cu, Fe, Pb, Ti and V) as well as the development of sodium-sulfate salinity, kaolinization and ferrugination. In phytocenoses supported by endothermal soils, species of order Rosales and Asparagales were overrepresented among obligate and facultative thermophytes respectively, and species of order Poales were underrepresented among facultative thermophytes in relation to the flora of the Valley of Geysers. Phytocenoses on the non-heated Andosols were enriched in Polypodiopsida species. The results of our comparative analysis of the thermally-induced variability in the soils and vegetation contribute to the general understanding of mineralogical, bio-abiotic and biological systems affected by steam-heated acid-sulfate waters. We hope that our findings will provide a basis for future transdisciplinary studies of the influence of steam-heated waters of a hot spring on the thermal landscapes.

“…The WSA of untreated volcanic and serpentine soils was 36.0 and 65.6%, respectively. In general, kaolinite is dominant in volcanic soils and smectite group clay minerals are dominant in serpentine soils [33] The The Mg-ex content in the 4% gyttja application was 3275 µgg −1 . All extractable heavy metal values tended to decrease with the addition of gyttja to serpentine soil.…”

“…The heavy metal content of soils formed on volcanic ash and andesite parent materials was reported as higher than that of soils formed on basalt, ignimbrite and dacite parent materials. In the same study, heavy metal concentrations in fruit, vegetable and water samples and heavy metals in blood and tissue samples from animals had a statistically significant correlation [32,33].…”

Organic matter is essential in improving the physical, chemical and biological properties of soils. Thus, the organic matter is widely considered a crucial indicator of environmental quality and biodiversity. In this study, the effect of gyttja addition as a soil conditioner on some physical and chemical properties of soils formed on volcanic and serpentine parent materials was investigated. The layout of the incubation study was randomized plots with 3 replications and the study lasted for 8 months to determine the value of gyttja in improving soil quality in two different parent materials. The results showed that pH, EC, total CaCO3, soil organic matter (SOM), wet aggregate stability (WSA), structural stability index (SSI), Ca-ex, Mg-ex, Fe-ex and P-av values of volcanic soils were significantly increased with increasing gyttja addition rates, while dispersion ratio (DR), Cu-ex and Cd-ex values were decreased. Likewise, pH, total CaCO3, SOM, WSA, SSI, Ca-ex and P-av values of serpentine soils were increased with increasing gyttja rates, while DR, Mg-ex, Fe-ex, Cd-ex, Ni-ex, Mn-ex, Cu-ex and Zn-ex values were decreased. The changes in the values of soil properties were statistically significant. The results demonstrated that gyttja addition overall decreased the erosion susceptibility and heavy metal contents of serpentine and volcanic soils. Moreover, the gyttja addition ameliorated some of the chemical soil properties. Therefore, gyttja could be suggested as a soil conditioner in the remediation of problematic soils.

Consistency of Mycorrhizal Effectiveness on Maize Growth and P Uptake in Two Generations of Pot Culture Using Andisol-Based Media

The functional roles of Arbuscular Mycorrhiza (AM) in soils with P limitations are well documented. However, the protocol to produce effective AM inocula was still limited. This research aims at obtaining the effective AM culture in handling P constraints for maize growth on Andisols. The first experiment of pot culture I was to propagate and examine the effectiveness of AM isolates by using a factorial completely randomized design with two factors, A=media (A0: zeolite; A1: representative media=Andisol Tengaran; A2: typical media=a mixture of Andisol Tengaran+Tawangmangu; A3: typical media+Bio-RP nutrition; A4: Inceptisol) and I = AM inoculum source (I0: no inoculum; I1: AM from Andisol Tengaran; I2: AM from Andisol Tengaran + Tawangmangu; I3: AM from 8 soil types), with six replications. The second experiment investigated the consistency of mycorrhizal effectiveness by reculturing AM cultures generation I to pot cultures generation II with the same composition of the respective media. The combination treatments of A1I3, A2I2, A0I3, and A4I3 (AM cultures generation I), continued by A1I32, A2I22, A0I32, and A4I32 (AM cultures generation II) showed consistently the highest AM infectivity and effectiveness on maize growth and P uptake on Andisol-based media, and on the comparison media of zeolite and Inceptisol media, respectively.
