Abstract

This study aims to determine the fertility status of irrigated paddy fields in various types of irrigation networks, as well as its relationship to crop productivity in the rice fields of Lawele Village, Lasalimu District, Buton Regency, Southeast Sulawesi Province. This research was conducted from June to October 2022. The method used is a descriptive method through field surveys and analysis in the laboratory. Sampling was carried out in a moving sequence based on the type of irrigation channel, and soil samples were taken at a depth of (0-20) cm. Soil chemical parameters analyzed were C-organic, total P2O5, total K2O, KTK, and KB. Determination of fertility status is guided by the PPT Soil Research Center, Bogor (1995). Problems that occur in irrigation in Lawele Village, Lasalimu District, are uneven distribution and poor physical condition of irrigation networks, as well as low soil fertility and crop productivity for various types of irrigation. The results showed that the fertility status of irrigated paddy fields on each land irrigated with various types of irrigation networks was very low. Fertility parameters that become obstacles in this soil fertility status are total K, total P, and some soil organic C which causes low land productivity in irrigated rice fields in Lawele Village. This is due to the leaching of soil cations as well as the lack of application of organic fertilizers and NPK by irrigation. Keywords: Fertility, Productivity, Rice Field

Abstract

Soil classification is needed because each type of soil has specific properties and characteristics, potential and constraints for certain uses. This study aims to classify soil according to local community knowledge on agricultural land lithosequences and their equivalents based on Soil Taxonomy in Latawe Village, West Muna Regency. The research method used is a free survey method that refers to the Geological Map Unit (SPG) with the type of soil profile observation. Soil classification according to local knowledge is carried out using a qualitative method with a social approach by interviewing the local community of Latawe Village and then matching the soil classification based on USDA Soil Taxonomy. The results of soil classification on agricultural land lithosequences according to local community knowledge are in SPG 1A (alluvium parent material) classified as wite kakuni (yellow soil), SPG 2A (limestone parent material) classified as wite kaghito (black soil), SPG 1B (alluvium parent material) classified as wite bhone (sandy soil), and SPG 2B (limestone parent material) classified as wite awu (calcareous soil). The results of soil classification according to local community knowledge are matched with Soil Taxonomy, namely profile I is included in the Inceptisols order, profile II is included in the Alfisols order, profile III is included in the Ultisols order, and profile IV is included in the Vertisols order. Lithosequences contribute to different soil properties and characteristics, both classified according to local farmer knowledge and the Soil Taxonomy system
