Abstract


Agricultural land in Indonesia is generally classified into two types: dryland and wetland. The

development of dryland agriculture is expected to contribute significantly to the agricultural

sector in Indonesia. This research aimed to examine the influence of soil conservation on soil

physical properties in Tilihuwa Village, Limboto Subdistrict, Gorontalo Regency, and to compare

the physical properties of soils in conserved (protected) and unprotected maize cultivation areas.

The research was conducted in Limboto Subdistrict, Gorontalo Province, and laboratory analyses

were carried out at the Soil Science Laboratory of Universitas Negeri Gorontalo from April to

July 2024. The research employed a survey method in which the conserved maize plots were

selected randomly. Based on the topographic layout of the land, soil sampling was conducted

according to slope classes, which were categorized into three classes. Soil samples were collected

randomly from five points within each slope class for both conserved and unprotected areas,

focusing on key physical soil properties. The results showed that conserved plots were classified

into three slope categories: 3-7%, 8-15%, and 16-25%. In contrast, the unprotected plots had

slope categories of 7-12%, 8-15%, and 16-25%.
