A field experiment was designed to follow the fate of fertilizer nitrogen in an annual crop (maize) and a permanent meadow (Digitaria decumbens) cultivated on an alfisol under the tropical two-season-climate of the Venezuelan Llanos.15N labelled urea equivalent to 150 kg N.ha−1 was added to field plots and to lysimeters of undisturbed soil.
