Assessment of land suitability for palmarosa cultivation (Cymbopogon martinii) as an atsiri essential oil plant in Karangturi Sub-District, Karanganyar, Indonesia

Abstract

Palmarosa (Cymbopogon martinii) cultivation has gained significant interest because of the increasing demand for its essential oil (atsiri) in many industries. This research set out to thoroughly evaluate the land’s potential for palmarosa agriculture in the particular Karangturi Sub-District, located within the Gondangrejo District of Karanganyar Regency. This research employs a comprehensive approach to remote sensing, soil sampling, and geographic information system (GIS) analysis. It thoroughly examines and evaluates important factors including soil texture, pH levels, nutrient composition, topographical features, and climatic nuances, comparing scientific sources. According to the study’s findings, Karangturi Sub-District’s land area is at the marginal level (N; NW), which means it is not suitable enough for growing palmarosa due to the limiting factor for water availability. However, on other parameters, the status was suitable (S1-S3). Instead, some areas may require soil management to make them more suitable for cultivation. Through a framework based on scientific research, this study not only offers information on land suitability but also provides a basis for Palmarosa cultivation, which in turn can develop local agriculture and increase palmarosa essential oil production in the region.
