“…In this study, concentration of Fe categorized as moderate are 225.56-910.00 ppm are relatively higher compared to that reported by Boyd et al (1994) measured in pond soils of Thailand, Philippines, Ecuador, and Venezuela which were 200-750 ppm. As discussed earlier that the volcanic soils have high capacity in retaining phosphate because this type of soil contains more Al and Fe which resulted in low P availability for plants and eventually results severity in plants productions (Qafoku et al, 2004;Van Ranst et al, 2008;Mejías et al, 2013;Galván-Tejada et al, 2014). The concentration of Fe that categorized as moderate are 83.50-4,580.60 ppm in pond soils of South Sulawesi had been reported by Mustafa et al (2015b).…”

“…Mustafa et al (2015b) reported that pond soils in South Sulawesi are mostly built on swamp land dominated by acid sulfate soils and peat soils indicated by low soils pH and high potential acidity. In contrast, volcanic soils dominating soils of Java Island have higher pH (Qafoku et al, 2004;Van Ranst et al, 2008). pH F is pH measured during the field work where the soils are still wet or commonly called as fresh soils.…”

Abstract:Soil quality plays pivotal role in increasing productivity and brackish water ponds successfulness, including ponds of Java Island, Indonesia. However, the availability of data on concentration categories for soil quality variables for ponds soils in Java Island, which is volcanic-dominated soils and the largest area for ponds in Indonesia, is still scarce. This study was aimed to categories soil quality variable concentrations as an initial point in interpreting pond soils quality of Java Island. Soil samples were collected from two different soil depths of 923 sampling points representing 13 regencies/cities of West Java, Central Java, and East Java Provinces. Twenty soil quality variables were measured based on in-situ and ex-situ measurements. The t-Student and U-Mann Whitney tests were applied to analyses the differences in soils quality at each soil depth which were firstly analyzed using z-score to eliminate outlier data. The data were firstly rearranged from the smallest to the largest data prior to measuring data deciles; the deciles, as considered as the basic measurement, were used for categorizing each soil quality variable. The results of this study indicated that the pH and nutrients are higher at pond top soils, 0-0.2 m compared to that observed on the depth of 0.2-0.5 m. Concentration of soil quality variables such as S KCl , S P , S POS , TPA, TAA, TSA, and pyrite relatively similar between the two depths. Data of each soil quality variable were categorized into very low, low, moderate, high, and very high to facilitate a comparison to other data of ponds soil qualities. The results of this study are not recommended for assessing the relationship between ponds soil quality and ponds productivity; yet are usefull in measuring which variable of ponds soil quality is categorized as very low, low, moderate, high or very high; and also useful in making decision on pond soils quality management in Java Island.

“…Marapi in West Sumatra (Fiantis 2000). Currently, Van Ranst et al (2008) reported that pyroclastic materials from Dieng volcano complex from Central Java consists of significant amounts of plagioclase feldspars, pyroxenes, rock fragments, olivine, and volcanic glass. Klein (2004) reported that the formation of plagioclase feldspar usually occurs at elevated temperature and is more abundant than alkali feldspars.…”

The Java Island, Indonesia with abundant amount of pyroclastic deposits is located in the very active and dynamic Pacific Ring of Fires. Studying the geochemical weathering indices of these pyroclastic deposits is important to get a clear picture about weathering profiles on deposits resulting from the eruption of Mt. Merapi. Immediately after the first phase of the eruption (March to June 2006), moist and leached pyroclastic deposits were collected. These pyroclastic deposits were found to be composed of volcanic glass, plagioclase feldspar in various proportions, orthopyroxene, clinopyroxene, olivine, amphibole and titanomagnetite. The total elemental composition of the bulk samples (including trace elements and heavy metals) was determined by wet chemical methods and X-ray fluorescence (XRF) analyses. Weathering of the pyroclastic deposits was studied using various weathering indices. The Ruxton ratio, weathering index of Parker, Vought resudual index and chemical index of weathering of moist pyroclastic deposits were lower than those of the leached samples, but the alteration indices (chemical and plagioclase) were slightly higher in the moist compared to the leached pyroclastic deposits.

“…Therefore, non‐allophanic Andosols in Japan are distributed in high rainfall regions such as the area adjacent to the Sea of Japan, and the Chubu district, and account for about 30% of the total (Saigusa & Matsuyama, ). However, there are many reports about soil profiles that have non‐allophanic properties in the upper A horizon and allophanic properties in the lower part of the A horizon (Van Ranst et al , ; Kubotera et al , ). Vacca et al () showed that allophanic and non‐allophanic soils in the Roccamonfina volcano, Italy, co‐existed in similar landscapes under similar climatic conditions, and concluded that allophanic soils developed in younger tephra than non‐allophanic soils.…”

Summary Unlike phosphate, an index of sulphate retention of soils has not commonly been defined. However, sulphate sorption by soils is more sensitive than phosphate sorption to the amount of their colloidal components. Sulphate has less sorption affinity than some organic acids or phosphate, and is sorbed by hydrous Al/Fe such as allophane but not by Al–humus complexes. Therefore, we attempted to categorize soils as allophanic or non‐allophanic Andosols by sorption experiments with sulphate. The method employed for sulphate retention (S‐retention) was based on the common method for P‐retention, using potassium sulphate solution (3.12 mmol SO42− l−1, equivalent to 100 mg S l−1) buffered by potassium acetate (pH 4.0) and shaking for 1 hour with a soil:solution ratio of 1:5. From the results from 172 soil samples of 30 forest soils in eastern Japan, a linear regression was obtained between S‐retention and Alo + 1/2Feo (r = 0.780, P < 0.001). All aluandic (non‐allophanic) soil samples (Sio < 0.6% and Alp:Alo > 0.5, in accordance with the WRB classification system) had poor S‐retention (< 60%) and were clearly divided from silandic (allophanic) soil samples. Highly weathered Cambisols with small activity ratios of free iron oxides (Feo:Fed < 0.4) tended to have greater S‐retention (> 30%) than less weathered Umbrisols and Cambisols with Feo:Fed > 0.4. In addition, these four soil types were separated as distinct domains on a scatter diagram of P‐retention plotted against S‐retention.
