Abstract

ABSTRACT The research was conducted in the Pugeran village, Yogyakarta in 2006.  The aims of this  research  were  to  know  the  morphology and  soil  characteristic.    Research  findings showed that the soil had many alluvial materials with different sizes (granular, rough and rather rough).  It was caused the activity of Merapi Mountain’s cold lava that was brought by river flow.   Observation and laboratory analysis indicated that some  soil characteristics were  soil color between 10 YR 2/2 and 10 YR 6/2, soil texture geluhan sand, pH (H20) 5,41-5,68, pH (KCl) 4,95-5,54, pH (NaF) 8,62-9,48 and organic materials 4,11%-9,44%.   The soil was dominated by brown and black colors, caused by the high content of organic materials in the inceptisol and entisol.   The soil texture” geluhan sand” was caused by the soil development and establishment processes that were not quite intensive.   The difference between pH (KCl) and pH (H2O) at all horizons in the profile had a negative value, with an interval of -0.15 to -1.35.  The negative value of the pH difference indicated that the soil in the observed area was dominated by negative content.   pH (NaF) was decreased by the increase of ”jeluk tanah”.  This was caused by the cleansing processes of iron and aluminum amorf in each soil horizon. Organic materials on the top horizon were higher than the other horizons.  This was because the top horizon received many organic materials coming from decomposed died plants and animals from higher areas.Keyword: Morphology, alluvial material, soil characteristic

Abstract

Ultisol still has the potential for the development of dry land agriculture. However, the utilization of Ultisol faces soil fertility constraints which can inhibit plant growth, especially bean plants, if not managed properly. The aim of the study was to determine the effect of manure and dosage on pH, organic C, total N, and yield of chickpea plants (Phaseolus vulgaris L.). The research was conducted at Field Laboratory II, Faculty of Agriculture, Halu Oleo University, from November 2021 to January 2022. The research was arranged according to a Split Plot Design with a factorial pattern. The main plot consists of three levels, namely chicken manure (KA), goat manure (KK) and cow manure (KS). Subplots consisted of 4 levels, namely: without manure (D0), 2% manure (D1), 4% manure (D2) and 6% manure (D3). The results showed that chicken manure, goat manure and cow manure had an effect on soil pH, C-organic and N-total. The highest increase in soil pH was achieved in chicken manure treatment (6.3), followed by goat manure and the lowest in cow manure. The highest increase in C-organic occurred in the chicken manure treatment (2.07%), then goat manure and the lowest was cow manure. The highest increase in N-total occurred in the cow manure treatment (0.13%), then the chicken manure and the lowest was in the goat manure treatment. There was no significant interaction between manure and dosage on bean yields. Manure has an independent effect on the number of pods and pod weight. The highest number of pods and the heaviest weight were achieved in the KK treatment with 20.17 pods and 97.17 g weight, followed by the KA treatment with 17.00 pods and 75.75 g weight and in the KS treatment with 3.25 pods and weighs 12.17 g.

Abstract

People's cocoa plantations in Padangguni District are generally located in a steep slope topographic condition with this condition the potential for erosion is very high which can affect land productivity in the community cocoa plantation area. The purpose of this research is to predict the actual erosion rate, determine the erosion hazard index classes, and recommend soil conservation alternatives on different slopes in smallholder cocoa plantations in Padangguni Sub-District, Konawe District. This research was conducted from October to December 2022 in Padangguni Sub-District, Konawe District. The survey method was used in this research, and the prediction of erosion rates was conducted using the USLE method on 3 land units: land unit 1 located in smallholder cocoa plantations with a slope of 6% covering an area of 14.6 ha, land unit 2 with a slope of 24% covering an area of 17.2 ha, and land unit 3 with a slope of 22% covering an area of 60.5 ha. The research results showed that the highest actual erosion occurred in land unit 3 at 1,307.74 tons/ha/year, while the lowest erosion occurred in land unit 1 at 1.12 tons/ha/year. The tolerated erosion rates were 31.61 tons/ha/year for land unit 1, 25.70 tons/ha/year for land unit 2, and 26.95 tons/ha/year for land unit 3. The highest erosion hazard index was found in land unit 3 at 48.52 tons/ha/year with a very high criteria, while the lowest erosion hazard index was found in land unit 1 at 0.04 tons/ha/year with a low criteria. The recommended soil conservation techniques to ensure the sustainability of smallholder cocoa plantations include applying vegetative conservation techniques using plant residues as mulch and mechanical methods through the construction of traditional terraces or roraks. Both scenarios of soil conservation action methods can reduce the actual erosion rate, making them appropriate choices for reducing erosion rates on cocoa plantation lands

Abstract

Nickel is an important main resource mineral in Southeast Sulawesi, which has deposited around 97.4 billion tons, and undoubtedly, nickel exports emerged in national and regional economic growth. Mining activities were carried out through topsoil and subsoil stripping, resulting in damage to the soil ecosystem and making it difficult for soil to recover. A study was performed to evaluate the changes in soil chemical properties and the growth of patchouli (Pogestemon cablin Benth) on nickel-mined soil treated with rice husk charcoal (RHC). A randomized block design was applied in this study, including six treatments of RHC with three replications. The treatments were without RHC (control), 1.5%, 3.0%, 4.5%, 6%, and 7.5% of soil weight. Data were analyzed descriptively for soil chemical properties; meanwhile, ANOVA was applied for plant growth. The results revealed that RHC increased soil pH, organic C, CEC, and available P, and conversely, the application of 4.5% of RHC decreased soil Ni and Fe content by 65.43% and 40.47%, respectively. The application of RHC up to 6% increased significantly the plant height and number of leaves as well as the dry weight of patchouli. The present study concluded that the use of carbon-rich soil conditioners such as rice husk charcoal is an imperative measure to restore the nickel-mined soil.
