Abstract

Cassava cultivation has been suggested to exhaust soil nutrient pools. This research was intended to evaluate the nutrient contents or availabilities in soils cropped continuously for several years with cassava. Soil samples were collected from a cassava plantation in Gunung Batin, North Lampung that has been cultivated for the time span ranging from 1 to 10 years. The results showed that soil organic matter and total N contents in cultivated soils were much lower than those in soil not cultivated. The soil available P, exchangeable K, and metal micronutrients (Fe, Mn, Cu, and Zn) in cassava soils were much lower than those in soils not cultivated or cultivated with corn or long bean.
