摘要: Abstract The relative tolerance to soil acidity of four annual legumes—biserrula (Biserrula pelecinus), French serradella (Ornithopus sativa), bladder clover (Trifolium spumosum) and arrowleaf (T. versiculosum)—was compared the more widely grown legume species, subterranean subterraneum). pH a Red Kandosol was adjusted with lime achieve five levels ranging from 4.2 5.8 in CaCl2. All species were inoculated an appropriate rhizobia strain half treatments received additional mineral nitrogen (N). Shoot weights all increased liming. value required 90% maximum herbage yield without N application c. 4.96–4.98 9.3% exchangeable aluminium (Al) for clover, biserrula, but significantly higher at 5.3 only 4.0% Al clover. Root nodule number insensitive liming except which showed large in...
