On target with precision ag

摘要

Ben first spoke with Crystal Brook grain producer Malcolm Sargent during 2006. At that time, Malcolm had been using precision farming equipment for seven years. In a follow-up visit during 2009, Ben caught up with Malcolm to see how his precision farming journey has progressed during the past three years. During 2006, as a result of variable rate application of phosphorus, Malcolm identified input cost savings of about 50 dollar-80 dollar per hectare over a set-rate blanket phosphorous application. In addition, a yield gain of 10% resulted through using GPS guidance assisted trials, yield and soil mapping to tailor fertiliser applications.
