Many soils of southern Africa are severely N deficient, but inorganic fertilizers are unaffordable for most sub-sistence farmers. Rotations and intercrops of legumes with crops may alleviate N deficiency through biological N2fixation and redistribution of subsoil N to the surface. We monitored soil inorganic N dynamics for two seasons in agliricidia [Gliricidia sepium(Jacq.) Walp.] – maize (Zea maysL.) intercrop in the unimodal rainfall area of southernMalawi. One maize crop per year was grown with or without interplanted gliricidia, in factorial combination withthree rates of N (0, 24 or 48 kg N ha
