The effectiveness in increasing N recovery by maize ( Zea mays L.) of N fertiliser (0, 60, 120 kg N ha-1 annum-1) and aerobically composted cattle manure (0, 12.5 Mg ha-1 annum-1 or 37.5 Mg ha-1 applied only in the first year) was determined when the two N sources were applied separately or in combination. A field experiment was established on a moderately leached sandy loam soil (Typic Kandiustalf) over three seasons, and N uptake was determined fortnightly from 4 weeks after planting (WAP) until harvest. Net N recovery during plant growth increased with N application rate (up to 90 kg N ha-1 in first season and up to 60 kg N ha-1 in second and third seasons). Net N recovery from manure during the growing period was relatively poor. There...
