Abstract

This study aims to determine the land suitability class and efforts to manage the limiting factors that exist on land in Lasalimu District, Buton Regency. The method used is an independent survey by taking soil samples in each land unit (LU) for analysis in the laboratory. The results showed that the longan plant was quite suitable (S2) to be developed at LU 25 and 27 with a land area of 65.69 ha (0.95%), marginally suitable (S3) at LU 1-3, 5, 8-14, and LU 23 with a land area is 1,828.10 ha (26.50%), and is not suitable (N) at LU 4, 6, 7, 15- 22, 24, and LU 26 with a land area of 5,004.71 (72.55%). Potentially if efforts are made to manage the limiting factors for the development of longan plants, the suitability class becomes quite suitable (S2) at LU 3, 5, 8-14, 23, 25 and LU 27 with a land area of 1,207.54 (17.49%), marginally suitable (S3) on LU 1, 2, 4, 15, 17, 19- 22, 24 and LU 26 with a land area of 4,787.76 (69.29%) and not suitable (N) on LU 6, 7, 16, and LU 18. Management actions that need to be taken for limiting factors of nutrient availability are fertilization, nutrient retention by liming and adding organic matter, erosion hazard with conservation efforts such as planting according to contours, making terraces and planting cover crops, while for limiting factors such as air temperature, soil depth, slope, surface rocks and rock outcrops cannot be repaired because the limiting factor is permanent

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

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.

Abstract

Soil quality is the ability of the soil to function to maintain plant productivity, maintain and maintain water availability and support human activities. The purpose of this study was to determine the Soil Quality Index (SQI) and determine the management direction for improving soil quality on different land uses in the Maginti sub-district. A field study and laboratory analysis were carried out from March to May 2022. The method used in this study was a free survey method through field observations conducted on 2 types of land use, namely irrigated rice fields and dry land. In irrigated rice fields, 3 sample points were taken and 3 sample points in dry land, then composited into 1 sample in order to represent the total amount of each land use. In calculating the value of the soil quality index using the formula by Bajracharya (2006) which has been modified by Ghimire (2018). The soil quality index is analyzed using the indicators that best represent soil functions. The variables observed included Texture, pH, C-Organic, N-Total, P-Available and K-Available. Soil quality index values range from 0-1, the higher the index value, the better the quality. The results of the analysis of the selected soil functions (minimum data set/MDS) and the MDS scoring were summed to determine the value of the soil quality index (SQI). The conclusion of this research is that the criteria for medium soil quality are irrigated rice fields with SQI (0,56) and dry land with low criteria with SQI (0,36). To improve soil quality in irrigated paddy fields and dry lands is to increase organic matter through the application of organic fertilizers with the right dosage according to the type and level of soil fertility.Keywords: Soil Quality Index, Irrigated Rice Fields, Non-Irrigation, Soil Management, Physical Properties of Soil Chemistry.
