Effect of Centrosema pubescens Benth on soil fertility in the humid tropics

Abstract

The present paper covers an investigation of soils under grazed guinea grass (Panicum maximum var. typica) and guinea grass/centro pastures of various ages. Comparisons of these soils with each other and with a soil under tropical
rain-forest are reported. From investigations of 16-yr-old swards, it is concluded that Guinea grass/centro pastures can play an important part in the tropics in maintaining soil-N and OM in the better soils and in improving these constituents in the poorer soils.
