Abstract

One of the Indonesian provinces where the agricultural industry drives the economy is Punung, Pacitan, which has local conditions that are particularly suitable for producing citrus, giving this product the potential to continue to expand in popularity. Land evaluation tries to provide information on its potential for a particular purpose. This research was conducted to know land suitability classes, limiting factors, and improvement efforts that can be made. This research is exploratory descriptive with a variable approach through field survey and using a purposive random sampling method based on Land Mapping Units. Data analysis was carried out using the matching method between land characteristics and conditions for growing citrus, a statistical test by ANOVA (Analysis of Variance), and Duncan’s Multiple Range Test (DMRT) to find the factors that most determine land characteristics in Punung. The study results show that the actual land suitability class in Punung is marginally suitable. Improvements that can be made to increase the availability of nutrients in the soil in the form of available P2O5 with a low level of management is to apply P fertilization according to the needs of citrus. ANOVA results proved that the variety of soil types significantly influences some of the land characteristics.

Abstract

Tawangmangu District, Indonesia, is located in a highland area with a cool climate and is predominantly composed of Andisol soil types, offering great potential for the development of potato crops (Solanum tuberosum L.). This study aims to examine soil physical properties suitable for potato cultivation, analyze the distribution of these properties across different slope gradients, and identify appropriate soil management strategies for the Tawangmangu area. The research employed a descriptive-exploratory approach, utilizing land map units (LMUs) that were determined through the overlay of soil type maps, rainfall data, slope gradients, and land use. The overlay resulted in 5 LMUs and 25 sampling points. Observed soil physical parameters included texture, porosity, permeability, consistency, effective soil depth, coarse material, and drainage. The land suitability assessment showed that LMUs 1, 2, and 3 were classified as S3-oa, limited by drainage, while LMUs 4 and 5 were classified as S3-oa,rc, limited by both drainage and effective soil depth. Slope gradient significantly affected moisture content (p = 0.022), bulk density (p = 0.037), particle density (p = 0.048), porosity (p = 0.032), effective soil depth (p = 0.001), and coarse material content (p = 0.032). Recommended land management efforts include the addition of organic matter, manual tillage for shallow soils, and the application of eco-drainage techniques to improve soil physical suitability for potato cultivation in Tawangmangu.
