Pasture production gains from strategic winter nitrogen applications on a North Island sheep and beef hill country farm

Abstract

Inadequate pasture growth from September to November has been a major constraint on animal production at Limestone Downs, Port Waikato. In an attempt to address this, urea was applied by air in two applications per year (late autumn + winter) at rates up to 250 kg N/ha/year for each of 3 years (2004-2007). Key words: nitrogen, slope, aspect, pasture growth, fertiliser response
