My Experience in a drought as a farmer and consultant – January 2011

Bill Crabtree (M.Sci) Multi-award winning sustainable agricultural scientist and Morawa farmer
In December 2007, I purchased 2,750 ha of arable land 38 km NE of Morawa, with the assistance of my father James and Rabobank. The farmland borders the edge of the rangeland and I estimate the long-term annual rainfall to be 305 mm. The farm had not been farmed much at all for the previous 8 years, from the year 2000, and five of these years were quite dry.

Urea is as effective as CAN when no rain for 10 days – 14 February 2005

Bill Crabtree, B.Ag.Sci., M.Sci.
When urea or calcium ammonium nitrate (CAN) were applied at the same N rate to Mundah barley 4 weeks after sowing, the yield response to urea was twice that of the CAN when the nitrogen (N) was applied just prior to a 27 mm rainfall event. Suprisingly, when these N fertilisers were applied after the rain and no rain fell in the next 10 days, the urea still performed as well as the CAN in terms of grain yield. With both timings, with respect to rainfall, the urea was economically better than the CAN where more than 20 kgN/ha was applied giving up to an extra $110/ha return.
