Abstract

This study aims to determine the quality of paddy soil, to determine the limiting factors of paddy soil quality, to provide land management direction in an effort to improve the quality of paddy fields and to make soil quality maps. This research was conducted in Nort Denpasar District from December 2020 to February 2021. Soil quality evaluation was carried out using field survey methods and laboratory analysis. Soil quality evaluation data analysis was carried out by matching and scoring based on limiting factors of 10 minimum data set (MDS) determinant of soil quality rating (SQR). The results showed that the soil quality in the study location was classified as moderate to good soil quality. Soils with moderate soil quality are found in SLH 3 and SLH 4 while soils with good soil quality are found in SLH 1 and SLH 2. The factor limiting soil quality in the study area is the low N and C-biomass. Based on the results of the study, the management directions at the research location can be determined, namely by adding organic matter, fertilizing urea, setting cropping patterns and applying intercropping.

Abstract

This study aims to determine the status of soil quality, limiting factors, and provide direction for land management, as well as make a map of the status of soil quality on stroberi land in Pancasari Village. The methods used in this research are field survey methods, laboratory analysis, and soil quality determination. Soil samples were taken by the purposive sampling technique on each homogeneous land unit. Determination of SLH was done by overlaying soil type maps, slope maps, and stroberi land used maps in Pancasari Village. Soil quality indicators measured as minimum data set (MDS): soil texture, volume weight, porosity, C- Organic, pH, Cation Exchange Capacity (CEC), Base Saturation (BS), nutrients (N, P, and K), and C-biomass. The results showed that the soil quality at the research site was moderate in SLH 1 (Buyan Hamlet), while the good soil quality was found in SLH 2 (Dusun Peken), SLH 3 (Dasong Hamlet, Buyan Hamlet), SLH 4 (Dasong Hamlet, Buyan Hamlet), SLH 5 (Dusun Peken, Dusun Buyan) and SLH 6 (Dusun Dasong). The limiting factors for soil quality in the research site were nutrients BS. Based on the results of the study, it can be suggested that the directions for soil management at the research site, namely by adding organic matter.

Abstract

This study aims to determine the status of soil damage, limiting factors, create a map of the status of soil damage, and provide recommendations for repairing soil damage. This research was carried out in Subak, North Denpasar District, from December 2020 to February 2021. The research method was carried out using a survey method, namely observation and soil sampling followed by laboratory analysis. Parameters analyzed were solum thickness, surface kerocks, fraction composition, total porosity, bulk density, electrical conductivity, pH, permeability, and the number of microbes. The results showed that the status of soil damage at the study site was classified as undamaged (N) and lightly damaged (R.I). The undamaged status includes Subak Dalem, Subak Lungatad, Subak Ubung and slightly damaged status includes Subak Kedua, Subak Pakel II, Subak Petangan, Subak Pakel I, Subak Sembung. The limiting factors of the research area are permeability and fraction composition. Recommendations for improvement from the results of the research are the application of Organic-Based Controlled Aerobic Rice Intensification (IPAT-BO) technology, such as the provision of organic matter in the form of rice straw residues and good soil management by plowing the land using cattle or tractor power.
