The process of refining iron by Blast Furnace (BF) or Electric Arc Furnace (EAF) produces steel and by-product: steel slag. This by-product can be used for various fields such as construction, industry and agriculture. This paper aimed to discuss the use of steel slag in agriculture as fertilizer, lime and ameliorant in the soils. The content of elements and compounds in steel slag is the basic component for the utilization of this material, therefore they are displayed quite completely. The presence of other contents like of heavy metals which are classified as hazardous toxic materials is also stated. Utilization of steel slag for agriculture has been carried out widely in various countries such as Japan, Germany and the United States. There have been many studies of steel slag in Indonesia that prove the benefits of steel slag in adding nutrients and improving soil reactions. However, the use of this material is still limited to research field, has not been widely used. Meanwhile, many research has proven that steel slag can improve some chemical characteristics like pH and CEC, as well improve Ca, Mg and Si content. Steel slag can release P from retention and fixation and Andisols and Ultisols. Research showed that steel slag improved the yield of rice, maize, horticultural and industrial plants.

ABSTRACT Andisols developed from parent materials of volcanic eruptions. Volcanic eruptions can occur within several periods, resulting in a sequence of soil layers that can differ from each period and produced lithologic discontinuity in the soil profile. Lithologicac discontinuity was investigated in Andisols developed from the eruptions of Mt. Tangkuban Parahu (Holocene, andesitic) and Mt. Tilu (Pleistocene, basaltic) in West Java through morphological observations of three profiles at each location. The results showed that there was lithologic discontinuity in all profiles indicated by changed in color by Munsell Soil Colour Chart, organic carbon, texture and structure as the specific A buried horizon that developed from the parent material of the earlier eruption period than the horizons above. It is recommended to carry out the mineralogical and micromorphological analyses to determine the differences in minerals and micromorphology of the discontinue horizons and carbon-dating analysis in the buried layer to determine the age of the soil and the period of eruption that developed the soil.Keywords: A buried horizon, Munsell Soil Colour Chart, organic carbon, soil mineralogy, soil morphology

The effort to utilize the soils optimally, especially Ultisols, requires an appropriate understanding related to their characteristics. The characteristics of Ultisols are sturdily influenced by soil-forming factors, viz. climate, parent material, pedogenic age and topography. The purposes of this study were to determine the chemical, physical, mineralogical characteristics and soil development classification level of Ultisol from two different types of parent rock. This research was conducted in Kampungbaru Village, Petir District and Sukalaksana Village, Curug District, in Serang Regency, Banten Province. These two villages represented different parent materials, namely andesite lava parent material of Holocene age (Kampungbaru Village) and tuff dacite parent material of early Pleistocene age (Sukalaksana Village). The research method was descriptive, comparative and survey. Soil classification was based on the Soil Survey Staff. The results showed that Ultisols developed from dacite tuff and andesite lava did not show contrasting differences in soil properties. The level of weathering of the two pedons was at the senile stage and the level of soil development of the two pedons was at the argillic stage. The soil classification of Kampungbaru pedon was Typic Palehumults, very fine, kaolinitic, isohyperthermic, while the Sukalaksana pedons was Arenic Paleudults, fine, kaolinitic, isohyperthermic

The application of steel slag and bokashi of husk in Andisols has been acknowledge to decrease P-retention and increase available P. However, steel slag contains heavy metals that may harm soils. The objective of this research was to find out the effect of amelioration steel slag and bokashi of husk in Andisols on the heavy metals contents (Cd, Pb and Cr) in the soil. The treatments were arranged in randomized block designed in factorial pattern with two factors: steel slag and bokashi of husk, each consisted of four level: 0, 2.5, 5.0 and 7.5 % in 10 kg soil weight (w/w), thus the total was 16 combined treatments and repeated three times. The treatments were incubated for four months and then the P-retention, available P, Cd, Pb and Cr contents in the soil were analyzed. The results showed that steel slag and bokashi of husk interacted in decreasing 6.67% of P-retention and increasing 60 ppm of available P. This research also informed that Cd, Pb and Cr contents in the soil after the treatments were still lower than the critical value that were permitted.

Lithologic discontinuity reflects the distinct change between different types of soil layers that can occur due to various geological process, resulted in variation composition, colour, texture, organic matter, consistency, structure, and others characteristics. Soils derived from volcanic eruption have the possibility to have lithologic discontinuity in the depth of the soil profiles due to the different eruption that formed the soils. Soils developed from the eruption of Mt. Patuha were investigated whether lithologic discontinuity presence the soil layers. The research used descriptive and comparative method of two profiles, analysed the soil macro-morphology and soil laboratory analyses covered colour, organic carbon, texture, consistency and structure. The result showed that the unusual pattern distributed of colour, organic matter, consistency, structure indicated the lithologic discontinuities of the underlying 2Ab (A buried) horizon to the overlying horizon. The darker colour, higher organic matter content, friable consistency in 2Ab in deeper depth, were some indications of lithologic discontinuities, where in soil without lithologic discontinuities the deeper depth or horizon was normally lighter colour, lower organic matter content and firmer consistency. However, detailed analysed with instruments like XRF and VIS DRS are needed to have the precise elemental composition in every horizon which conclude the horizon from the same or different parent materials.

Land use conversion can affect characteristics of soil and also soil quality. The present study evaluate theimpact of land use conversion from pine forest to bush in tropical volcanic soils in Indonesia. We comparedtwo soil profiles from the same areas (uphill slope of Mt. Tangkuban Perahu) and analysed theirmorphological, physical, and chemical soil properties. Our study showed that there was a decrease in soilorganic carbon stock about 3.7% (382 ton C ha-1) after approximately 8-15 years of land conversion. Other physical and chemical soil properties, such as soil texture, bulk density, pH, exchangeable base and acidity,cation exchange capacity, and base saturation were relatively similar. This research provide insight intohow change in vegetation cover can affect carbon and nutrient dynamics as well as become a baseline tounderstand soil recovery potential if the land is restored to forest or bush in volcanic soils.
