<p>The effect oflegume cover crop on soil characteristics was studied to know the possibility of using<br /> legume cover crop as soil amendment for the next generation of Gmelina arborea Roxb. plantation<br /> forest Three species oflegume cover crop: Crotalaria anagyroides (CRY), Mucuna chochuchinensis<br /> (MC) and Colopoginium caeruleum (CC) were planted at the fonper field of G.arborea plantation<br /> forest CRY is not a creep tree and has a good suitability to grow well and fast to flower. The growth<br /> rate of Mucuna sp was relatively high and covered soil surface rapidly. The initial growth rate of<br /> Colopogium sp was relatively slow, but finally covered soil surface well, thick and remained for a long<br /> time. Biomass in CRY was the highest (28,5 tonlha), followed by MC (26,S tonlha) and CC (19 tonlha).<br /> Carbon content of each legume cover crop was about 50% of its dried weight biomass. Organic matter<br /> and C, N, P, K, Ca, Mg and Fe contents were higher than the other non-legume species in the plot. Soil<br /> characteristics were affected by legume cover croP? especially in the top layer. Legume cover crop can<br /> improve soil properties and become a good soil amendment for the next rotati</p>
