Fertility studies of the major soil series in Natal: a field-scale test of experimentally established economic optima for N, P, and K on an Avalon medium-sandy-loam, 1971-1974

, : Fertility studies of the major soil series in Natal: a field-scale test of experimentally established economic optima for N, P, and K on an Avalon medium-sandy-loam, 1971-1974. Agricultural Research 1978: 97-99

Between 1966/67 and 1970/71 efforts were made at the Dundee Research Station to determine the optimum rates of N, P, and K fertilization for maize on the sandy Avalon soils of northern Natal. Results obtained were considered useful and a fertilization programme for maximum profits per hectare was developed. The experimental results indicated that long-term yields averaging between 5800 kg/ha and 6400 kg/ha are possible at Dundee.
