Conteúdo: | Abnormal defoliar is prevalent in citrus prodcing districts in Japan. The symptoms of defoliation appear first as brown or chocolate-coloured spots at the leaf tip in autumn or winter, and then the leaf falls off. Studies were carried out on the chemical composition of soil, leaves and roots from abnormal orchards and adjacent nomal orchards. The pH value and contents of exchangeable calcium were lower in the subsoils of abnormal orchards than in the subsoils of normal ones.
