Abstract

Siamese oranges are one of the most widely developed horticultural crops in Indonesia. Arjosari and Ngadirojo are some of the sub-districts that produce Siamese orange in Pacitan Regency. One of the factors that can affect the development of citrus is land quality. This study aims to obtain land quality index data and improvement efforts for developing Siamese orange. Soil samples were taken from 25 land mapping units (LMUs) with 87 sample points. The soil sampling points were determined based on area or sampling density. Data analysis used for soil quality assessment includes correlation, principal component analysis (PCA), minimum data set (MDS), and calculation of climate quality index. The parameters used in this study are bulk density, porosity, moisture content, texture, pH, electrical conductivity (EC), cation exchange capacity (CEC), base saturation, total N, available P, available K, soil organic carbon (SOC), microbial biomass carbon (MBC), evapotranspiration, temperature, and solar radiation. Based on the results of soil quality analysis in the study area, it has a value range of 0.28 to 0.37, including low class, while the climate quality index is 1.39 with moderate class. The land quality index has a very low to low class with a value of 0.39 to 0.51. Intrinsic, extrinsic, and anthropogenic factors can influence soil quality. The study area’s limiting factors for developing Siamese oranges are EC, total N, and available P, which can be improved by making furrow ponds, adding organic fertilizer, using urea fertilizer, and SP36 according to the dosage.

Abstract

Soil density is a crucial parameter for soil physical health. It influences the ability of plant roots to penetrate the soil, which in turn impacts the plant's absorption of water and nutrients. The research was conducted in Jatipurno Subdistrict, Wonogiri Regency, to determine the distribution of soil density, the influence of sources of diversity, the determinants of soil density, and recommendations for land use. Descriptive exploratory research through survey and laboratory analysis was employed in this study, with soil density measured using the Dynamic Cone Penetrometer (DCP). The quite high soil density class covers 2,631.28 ha (60.51%), and the high soil density class covers 1,716.87 ha (39.49%). Land use did not significantly affect soil density, whereas soil type, slope gradient, and rainfall did. Soil density values have a significant positive correlation with bulk density (r = 0.862; P-value = 0.000; N = 45) and texture (r = 0.572; P-value = 0.000; N = 45), and have a significant negative correlation with water content (r = -0.457; P-value = 0.002; N = 45), porosity (r = -0.699; P-value = 0.000; N = 45), and organic C (r = -0.404; P-value = 0.006; N = 45). These five parameters were selected as determining factors, increasing bulk density and texture (clay content), and decreasing water content, porosity, and organic C will increase soil density. Improved land management, based on these determining factors, is needed to increase agricultural land use for sustainable agricultural production, such as mulching, increasing organic matter content, and minimal tillage to maintain soil surface moisture.
