Abstract

Six pasture grasses, Paspalum notatum cv batatais, P. notatumu cv pensacola, Brachiaria radicans, B. ruzizensis, B. decumbens and B. humidicola, were grown in concrete cylinders (60 cm diameter) in the field for 31 months. The soil was amended with either a single addition of 15N labelled organic matter or frequent small (2 kg N/ha) additions of 15N enriched (NH4)2SO4. In the labelled fertilizer treatment soil analysis revealed that there was a very drastic change in 15N enrichment
