Spectroscopy studies material responses to the incident electromagnetic radiation. This method has been proven to be cost-effective for either soil or plant nutrient analysis. Furthermore, it offers rapid and high throughput quantitative data measurement with non-destructive, waste-free and minimal sample preparation processes. This article reviews potential use of spectroscopy technology in land resources monitoring as the cost-effective solution, particularly in the developing nations where natural resources monitoring might not be part of national development priority. The discussion is focused on the use of visual/near-infrared spectroscopy (VNIRS) for soil nutrients prediction, particularly to support cropland nutrient management of three main food crops in Indonesia, i.e. paddy, maize, and soybean.
