Abstract

One strategic issue in regional development is sustainable food security. Sweet potato tubers can be used as an alternative local food ingredient so that they play a role in supporting food diversification activities. The aim of the research was to evaluate the land resources needed for sweet potato growth. The method used is survey and analysis of soil samples to determine the physical and chemical properties of the soil. The results of the research show that the actual land suitability in Walesi District in zone A is classified as class S3-r 2,f 4,n2,i1,e2 with limiting factors in the form of soil depth, alkaline pH, low available P2O5, the presence of rock outcrops, and slope hazards. Zone B is classified as class S2 and has the potential to become class S1 by improving the limiting factors in the form of increasing the availability of P2O5 by fertilizing using balanced synthetic fertilizer, adding soil organic matter, and applying phosphate solvent microbes. Meanwhile, in zone C it can be improved with organic materials, and increase the availability of P2O5 in the soil with sulfur powder
