<![CDATA[Fly-ash (FA) is largely alkaline in nature and contains many essential elements for plant growth along with toxic metals. Therefore, fly-ash is potential to be applied as soil ameliorate that may improve soil properties and plant growth. In this experiment we studied the changes in chemical properties and rice production of acid sulphate soils amended with fly ash. Six different amounts of FA, viz. 0 (100% soil), 5, 10, 20, 40 and 75 tones FA ha-1 were added homogenously to 6 kg of soils in pots of PVC and then chemical properties of acid sulphate soils were observed after a 3-week of incubation. Subsequent of the observation of soil properties, rice was planted onto the pots. Results of study showed that fly-ash application improved soil pH and exchangeable Ca. However, the availability of nitrogen of acid sulphate soils decreased significantly with fly-ash application. The experiment also showed that fly-ash application to soils improved rice growth (height plant, number of tillers, dried-weight root and dried-weight shoot) and rice production. Application 20 tones FA ha-1 resulted in higher rice production than the application 0, 5 and 10 tones FA ha-1, and increasing subsequent the amount of FA application did not significantly increase the rice production. Results of this study demonstrate that low-level fly-ash application resulted in the improvements of soil chemical properties and rice production.Key words: fly-ash application; soil ameliorant; heavy metals; sub-optimal low land.]]>

<![CDATA[The raised-bed soil is a land management technology in South Kalimantan. Adding Ameliorant to the raised-bed soil as an effort to increase the utilization of support for the cultivation land. Chlorophyll or leaf green substances found in all green plants that carry out photosynthesis. Ameliorant applications can increase the chlorophyll content of plants to optimize plant growth. This study aims to look at the effect of giving several types of ameliorant to the content of chlorophyll (chlorophyll-a, chlorophyll-b and total chlorophyll) and the growth of corn planted on raised-bed soil. This research is an experiment in the laboratory and a greenhouse. This research was conducted using a Completely Randomized Design (CRD) Single Factor with the treatment tested was the type of ameliorant soil without treatment (control - K), soil + agricultural lime (dolomite - C), soil + palm empty fruit bunch ash (S), soil + rice husk ash (P) and soil + coal ash (B). All treatments were repeated 5 (five) replications so that there would be 25 units of the experiment. The results showed that the application of ameliorant in raised-bed soil using dolomite and oil palm empty fruit bunches ash with a dose of 5 tons ha-1 affected the content of chlorophyll-a and total chlorophyll in the growth of corn planted in raised-bed soil materials.]]>

<![CDATA[Mining activity may potentially produce acid mine drainage (AMD), which has relatively high acidity and dissolved heavy metal concentrations. Constructed wetlands is one of the AMD management methods in which organic matter (OM) plays a very important function in reducing the concentration of heavy metals in AMD through absorption and precipitation processes. Three types of OM (empty fruit bunches of oil palm, chicken manure and water hyacinth) and five levels of OM (0, 10, 20, 30 and 40 Mg ha-1) were applied to reclaimed-mining soils (RMS) in an incubation study. A batch experiment was then performed to measure the effect of OM application on the maximum sorption capacity (Qmax) of iron (Fe) from the AMD onto the mixed soil-OM. The application of OM resulted in increases in soil pH, carboxylic groups, and total functional groups, in which these increases varied based on the types and amounts of OM application. This study also revealed that OM application resulted in increasing Fe sorption. The application of OM increased Qmax values from 2077 to 2348-3259 mg kg-1 (water hyacinth), to 2607-3635 mg kg-1 (chicken manure), and to 2219-2992 mg kg-1 (empty fruit bunches of oil palm). Increasing these Qmax values may ascribe to increasing functional groups of the RMS with OM application. The results prove the importance of OM in controlling the sorption of Fe from AMD onto soils.]]>

<![CDATA[Coal fly ash, resulted from coal combustion in power plants, with relatively high amounts of aluminium, iron, calcium, and magnesium oxides may modify the sorption capacity of soils. A batch experiment was conducted to examine the capacity of reclaimed mining soils (RMS) to adsorb organic carbon (OC) in response to coal fly ash application. Extraction of dissolved OC was carried out from dried albizia shoot residue and reacted with the RMS at dissolved OC concentrations varying from 0 to 175 mg C L-1 at pH 5.5. The results showed that the sorption capacity of the RMS for OC increased significantly with coal fly ash application, which may relate to increasing the contents exchangeable Ca and Mg, dithionite- and oxalate-extractable aluminium and iron, and surface areas of soils. Desorption experiment indicated that only 5-23% of the OC initially sorbed onto soil-coal fly ash interactions was freed using a single extraction step, suggesting that most of the OC is strongly sorbed to the mineral surfaces. Results of the study indicate an important role of fly ash in increasing OC sorption capacity of soils and reducing the percentage of OC sorption from the RMS-coal fly ash association.]]>

<![CDATA[An understanding on relationship between water content and mineralization of carbon (C) and nitrogen (N) across soils varying in physical and chemical characteristics is required to assess the influence of soil physico-chemical properties on soil organic matter decomposition. However, such information is rarely available. Relationship between C and N mineralization of three soils varying in physico-chemical properties with different measurements of water content (water-filled pore space, gravimetric water content, volumetric water content, and water holding capacity) was studied through an incubation experiment for 8 weeks. Results of the experiment showed that C and N mineralization increased with increasing water content, reached a maximum, and then decreased with subsequent increasing water content levels. Maximum C and N mineralizations were observed at 70-80% and 50% water-filled pore space (WFPS), respectively. The ranges of WFPS for C and N mineralization were the narrowest among other measurements of water content. Therefore, it was likely that a single WFPS could be used in subsequent incubations to examine either C or N mineralization of soils with different characteristics. Result of this study suggests that the preliminary experiment on the relationship between mineralization of C and N and water content is necessary to do where mineralization is needed to be assessed in soils that have different physico-chemical characteristics.Keywords: Carbon and nitrogen mineralization, percent of water-filled pore space, water content[How to Cite : Saidy AR. 2013.

<![CDATA[Relationship Between Concentration of Cr(VI) and Soil Chemical Characteristics: Preliminary Information for Remediation of Ex-mined Lands in the South Kalimantan (A.R. Saidy and Badruzsaufari): High concentration of heavy metals is frequently observed as an effect of mining activity. In order to determine relationship between concentration of Cr(VI) in ex-mined land and soil chemical characteristics, 15 of soils were sampled from ex-coal and chromate mined-lands in the South Kalimantan Province. Result of the experiment revealed that soils from the ex-mined lands contained 700 - 2645 mg Cr kg-1 soil. This research also showed that 0,73-1,35% of total Cr in these soils exist in the form of hexavalent chromium (Cr(VI)) that is toxic and carcinogen. Concentration of Cr(VI) in these soils were correlated significantly with soil pH in which increasing soil pH would lead to increase in concentration of Cr(VI). In addition, increasing in soil organic carbon will be followed by decreasing concentration of Cr(VI). Relationship between concentration of Cr(VI) and soil pH and organic carbon content could be useful for preliminary information for Cr reclamation of ex-mined lands.]]>

<![CDATA[Acid mine drainage (AMD) is resulting from the exposure of rock containing ferrous of ferric sulfide mineral to rainwater and oxygen result in the generation of AMD. AMD characterized by highly acidic pH water with pH range ≤ 5 and containing heavy metals (Fe, Mn, Al) with high concentration. Therefore, AMD must be treated to ensure safety and minimize the environmental risk in order to request from the Ministry of Environmental Readmitted Number 113 the Year 2003. The solution is using a passive treatment method with constructed wetland technology. Empty oil palm fruit having nutritive content with high relativity like N, P, K and if it is composted having pH value till 8 so that is potential to improve soil and water acidity. This research is to know the effect of giving variations measurement of empty oil palm fruit to constructed wetland technology for acid mine drainage management to fit the value of quality standard liquid wasted coal. This study using a randomized block design consisting of a single factor with 6 treatments and 3 replicants. Research has shown that giving various measurements of empty oil palm fruit has a real impact to increase the pH value, and decreasing Mn at AMD, but has no real impact on decreasing Fe (Fe2+) value. ]]>

<![CDATA[The use of fly ash as a material for amelioration has been applied in some countries. Fly ash is amorphous compound of silicate-aluminum-iron that contains essential nutrients for plants. Fly ash has a pH of about 8.5 and has chemical properties that can be used as a source of neutralizing acidity in the soil. This study aims to determine the effect of fly ash as a soil ameliorant of soil on dry land and paddy soil in Kalimantan Selatan . Soil samples on dry land were taken from Sungai Riam, Tanah Laut Regency. Soil samples on paddy soils were taken from Sungai Rangas, Banjar Regency. Six kilograms of each soil samples placed on 8-L pots. Fly ash is added to each pot with a dose of 0, 25, 50 and 75 tons ha-1. All treatments were made in four replicates using completely randomized design. Data were collected for soil pH, total-N, total-K, total-P, and cation exchange capacity. The results showed that only the soil pH and soil CEC significantly affected by the addition of fly ash. Application of fly ash by the number 50 - 75 tons per hectare compare 25 tons per ha does not provide a significantly difference to pH and CEC]]>

<![CDATA[One of the problems in phosphate nutrient fertilization is a low level of efficiency, so the application of arbuscular mycorrhiza is often done to increase phosphate uptake. In this study mycorrhizal was applied to shallots which were given P fertilizer to assess the effect of mycorrhizal applications on growth, yield, and phosphate uptake. This research was carried out at the Faculty of Agriculture's Greenhouse of the University of Lambung Mangkurat Banjarbaru from March to May 2016. The seed of shallot was grown on 5 kg of soil and quartz sand (3:1) fertilized by P (0, 50, 100, 150, 200 and 250 kg SP-36 ha-1) and applied with mycorrhiza (without and with 10 g of plant-1 mycorrhizal inoculum) at planting. The observations made after 75 days after planting showed that the application of arbuscular mycorrhiza was effected to improve several observation variables, namely plant dry weight, bulb dry weight, phosphate nutrient uptake, and phosphate efficiency. The application of mycorrhiza at phosphate doses of 250 kg SP-36 ha-1 can increase plant dry weight by 97% and bulb dry weight by 203% compared to without mycorrhiza. Whereas the application of mycorrhiza at a phosphate dose of 100 kg SP-36 ha-1 is the best and most efficient treatment to increase phosphate nutrient uptake and phosphate efficiency. The results of this study show that the application of mycorrhizal can increase nutrient uptake of phosphate which ultimately increases the growth and production of shallot plants. ]]>
