“…High variability of soil characteristics in the same soil series has also been reported in Malay Peninsular by Law & Tan (1977). It also has been reported that the characteristics of brackishwater ponds soil in Indonesia are similar to those in Pekalongan City Central Java Province (Asaad & Mustafa, 2011) and Pangkep Regency South Sulawesi Province (Rachmansyah & Mustafa, 2011) which have relatively high variability or relatively heterogeneous. Vertical spatial distribu- Redox potential describes the condition of the soil which is oxidized or reduced.…”

Spatial distribution of brackishwater pond soil has important role in the system of bioenvironment including brackishwater pond environment. This research was aimed to determine the spatial distribution of some chemical characteristics of an acid sulfate soil-affected brackishwater pond in coastal area of Luwu Regency South Sulawesi Province, Indonesia. ALOS AVNIR-2 images (acquisition 16 May 2008, 16 October 2008, 17 September 2009) were integrated with Indonesian Topographic maps to obtain base map. Sampling soil points were determined by simple random sampling in 104 points for two different soil depths i.e. 0-0.2 m and 0.5-0.7 m. A total of 18 soil chemical characteristics was measured in the field and analyzed in the laboratory. Geostatistic using kriging method in the ArcGIS 9.3 software was used to interpolate the data. The results of this study indicated that in general pond soil chemical characteristics in Luwu Regency could be categorized with high variability or relatively heterogenic wi th the value of var iation coefficient more than 36%. The soil characteristics that explain acidity had shown similar pattern in spatial distribution as well as other soil characteristics with soil nutrient. The high value of pH and low value of PO4 were generally found in the northern part of Luwu Regency, including East Lamasi, East Walenrang, Bua, and Ponrang Subdistricts. It is recommended that soil management in brackishwater ponds of Luwu Regency could be based on soil chemical characteristics so its could improve the production through minimizing the input, increasing carrying capacity, and avoiding environmental degradation.

“…Volcanic soils were formed through a weathering of volcanic dusts; this soil type is also distributed to the low land of Java by wind transport. However, alluvial, which are acid sulfate soils and non-acid sulfate soils also found on pond soils in a small specific area of Java Island (Asaad and Mustafa, 2011;Mustafa and Athirah, 2014;Mustafa et al, 2015c Table 3: Categories of brackishwater pond soils quality variables at the depth of 0.2-0.5 m of Java Island, Indonesia.…”

“…Data of this study were then compiled from studies collecting data of soil quality variables through the studied area, Subang Regency (Tarunamulia et al, 2015), Indramayu Regency (Utojo et al, 2013b), Brebes Regency (Suhaemi et al, 2013, Pekalongan (Asaad and Mustafa, 2011), Demak Regency (Mustafa and Athirah, 2014), Pati Regency (Mustafa et al, 2015c), Tuban Regency (Utojo et al, 2014), Lamongan Regency by Utojo et al, 2012), Gresik Regency (Utojo et al, 2013a), Pasuruan Regency (Utojo et al, 2013c), and Regency and City of Probolinggo (Kamariah et al, 2014). Data analyses were initialed by determining outlier data of each soil quality variable using standard score (Z-Score).…”

“…The soils in Java Island, especially in northern and eastern coasts are dominated by volcanic soil (Supriyo et al, 1992;Jensen, 1993;Devnita et al, 2010;Erfandi and Rachman, 2011;Widiatmaka et al, 2016) that has specific characters; therefore the soils show particular character and different from soils outside Java Island. In addition, some studies conducted in shrimp ponds of Java island only assessed land suitability for shrimp pond (Utojo et al, 2012;Utojo et al, 2013a;Utojo et al, 2013b;Utojo et al, 2013c;Suhaemi et al, 2013;Utojo et al, 2014); spatial distribution of soil variables (Asaad and Mustafa, 2011;Kamariah et al, 2014); influence of water and soil qualities on shrimp production (Mustafa and Athirah, 2014), traditional shrimp pond management (Mustafa et al, 2015c) and feasibility of silvofishery (Tarunamulia et al, 2015). This study was aimed to provide information on categories of soil quality variable concentrations at two different soil depths of pond soils in Java Island.…”

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.
