Abstract

Heavy metals are potentially toxic to soil microorganims and are suggested to decrease soil enzymatic activities. Changes in activity of acid phosphatase in root-zones of some tropical plants treated with a lead-containing industrial waste were studied in a glasshouse experiment. Tropical soil sample (from Gedongmeneng and Banjaragung, Lampung) thoroughly treated with an electronics industrial waste at 0 to 40 ton ha·1 and lime at 0 or 5 ton CaC03 ha·1 were cultured with corn (Zea mays L.), amaranth (Amaranthus tricolor L), and green kyllinga (Cyperus kyllinga). Changes in acid phosphatase activity, soil Pb concentration, and soil pH were measured after a 4-week growing period. Soil analysis showed that the activity of acid phosphatase was higher in Banjaragung soil than that in Gedongmeneng soil except in those cultured with green kyllinga. The activity of acid· phosphatase was in general higher in the root-zone of corn than those in the root-zone of amaranth and green kyllinga.The activity of acid phosphatase in both soils decreased with waste addition regardless of plant grown. This was in a good correlation with the increase in soil available Pb as waste was added. However, the decrease in the activity of acid phosphate as the soil pH increased by lime or waste addition suggested that the decrease in the phosphatase activity with waste addition was driven by the increase in soil pH rather than by the increase in the soil available Pb With waste 3dclitton.

Abstract

Regarding environmental degradation in Puncak and its surrounding area due to the rapid landuse changes during 1981-1994, some mitigation schemes for soil erosion have been implemented but landslides. Data on landslide and its causative factors (landuse, soil, geology, slope, climate, and terrain mapping unit) and their relationships in the area are still not available. The objective of this research is to develop the method and procedures to map landslide hazards by using GIS (Geographical Information System) univariate-statistical analysis applied to the area as a case study. For this purpose, three methods to classify and to map landslide hazards were evaluated. They were respectively developed by considering: (a) unweighted density total number of the landslide, Method#1, (b) density total number, weighting value, and age of landslide, Method#2, and (c) density total number, weighting value, age, and activity level of the landslide, Method#3. The density number is counted by overlying· each of the landslide maps and each of the causative factors maps used, and from this step, the weighting value is derived. The resulting density number of landslide given as a cumulative percentage and the corresponding weighting value were then plotted on an X-Y graph. From the graph, the level of landslide hazard is classified by applying: (1) standard classification procedure as the default statistical analysis given by the software used, and (2) natural classification procedure as it based on the nature of the curve slope of the cummulative graphic. The result given by the three methods were varied but in general, they gave landslide hazard maps with a similar pattern in which the very high and very low hazard levels in the study area increased during the period of 1981-1994. Of the three methods, applying the natural classification gave a better result than that of the standard classification procedure. Method#2 and Method#3 were better than Method#1 in predicting the future landslide occurrence. Apparently, Method#3 should show the best result but the effect of conversion from raster to vector data in GIS significantly reduced the quality of the resulting map.

Abstract

This laboratory experiment was carried out to study the effect of soil samples drying on the physical and chemical properties of vertic soils and their classification according to soil taxonomy. Usually, soil analysis is held on samples in air-dried condition. Clays of some soil types, however, have irreversible properties upon drying which can cause a bias in the measurement results and classification outputs of the soils. To study the irreversibility of clays upon drying, 25 samples of vertic soils were treated in moist and air-dried conditions prior to analysis. The statistical procedure of Match Pair Comparison was used to test the effect of the treatments. The results showed that the irreversibility of day upon drying was reflected in the measured soil properties except for exchangeable-A! and -K, organic-C. and soil-CEC. Nevertheless, the intensity of the day irreversibility of the vertic soils studied was low. Therefore, the drying treatment did not affect their classification outputs.

Abstract

Results of the study on morphological, physical, and chemical characteristics of three pedons developed on volcanic materials of Mt. Galunggung, namely BM1, 8M2, and 8M3, showed that these pedons had a different stage of profile development. Pedon BM1 is classified as undeveloped, 8M2 is medium developed, and 8M3 is strongly developed. This is mainly caused by differences in the relative age of the parent rocks and elevation. Although classified as undeveloped, the soil represented by pedon BM1, the youngest, has immediately been used by farmers for rice cultivation because of water abundance, and high availability of P, and basic cations derived from weathering of easily weathered amorphous materials and minerals. According to the Soil Taxonomy system of the USDA (Soil Survey Staff, 1996), pedons 8M1, 8M2, and 8M3 are classified as Typic Udipsamment, Taptho Hapludandic Typic Troporthent, and humic Hapludult, respectively. Whilst, according to the FAO/UNESCO system (1988), these pedons are classified as Eutric Regoso/, Eutric Regosol and Humic Aliso/, respectively.

Abstract

Micromorphology is a branch of science in soil science. In micromorphological studies, soil samples are first prepared as a thin slice (with various methods), then the phenomena inside are examined using a microscope. By knowing the composition, shape, orientation, distribution patterns, structures, etc., the phenomena that occur can be interpreted, both regarding the composition of the soil, the relationship between components and the dynamics of the process that has been, moderate or expected to occur in the soil. Thus, micromorphology can and is very prospective to be developed and applied for various uses outside the field of soil science.
