The impact of farming without nitrogen fertiliser for ten years on pasture yield and composition, milksolids production and profitability; a research farmlet comparison

Year: 2013

Type: article

Abstract: Two experimental farmlets were established in the 2001/02 season and run continuously to 2010/11, comparing the impact of two nitrogen (N) fertiliser systems on milksolids (MS) production, profitability and the yield and composition of ryegrass-white clover pastures. Treatments were: 1) No-N. No N fertiliser applied, stocking rate 2.56 cow equivalents/ha (including replacements); 2) Control. Average of 181 kg N/ha/year applied as urea, stocking rate 3.06 cows/ ha (replacements grazed off farm). Annual pasture production was, on average, 2.9 t DM/ha greater on the Control farmlet compared with the No-N farmlet (P
