Abstract
Abstract. Mining activities using open pit techniques cause land damage such as decreased soil fertility, heavy erosion, and loss of topsoil. Decreased soil chemical properties so that it cannot support the plant root system and will have an impact on abnormal plant growth. This study aims to determine changes in the chemical characteristics of nickel mining soil after the addition of organic matter. This research uses location survey methods and laboratory tests, as well as literature studies. The results showed that the addition of organic matter to the soil could reduce the toxic elements in the soil and improve soil aggregates. The chelating ability of organic matter is proven to improve soil chemical properties.
