Abstract
Coffee plantation in south Sumatra, Indonesia, is developed on the slopes in hilly areas, where soil erosion is a severe problem. Introduction of weed as cover plant has been found to be effective in the reduction of soil erosion. Here the effect of weed management, weeding and coverage with Paspalum conjugatum Berg. or natural weeds, on soil chemical properties was investigated. After 4 years, contents of total C, total N, available P, and exchangeable _ex._Mg in the 0–10 cm and 10–20 cm depth layers were significantly greater in the Paspalum conjugatum and natural weed plots than in the weeding plot. In the 0–10 cm layer, ex-K and ex.-Ca were also greater in the weed-introduced plots than in the weeding plot. Decrease in soil pH _H2O_and the increase in ex. Al under coffee plantation were reduced by the coverage with weeds. Thus soil coverage with weeds in coffee plantation on slopes was effective in the maintenance of soil fertility.
