Pastoral Robotics Ltd was very excited to have its first farm-scale, farm-ready 8 metre wide Spikey on display at the 2017 National Fieldays, June 14-17.
Designed for 3-point-linkage tractor mounting, this equipment for detecting fresh urine patches and same-pass treating them its patented ORUN spray takes less than 10 minutes per ha to control the biggest threat to ongoing consenting of dairy farming; nitrate leaching from urine patches.
Using technology developed here in New Zealand by Pastoral Robotics founders Geoff Bates and Bert Quin, Spikey can detect and spray fresh urine patches on a follow the cows basis. The recovery by pasture of the huge amount of urine-N deposited in urine patches (400-1000 kg N/ha within the patches) is increased by an average of 70%, automatically greatly reducing nitrate-N leaching, increasing pasture growth, and reducing fertiliser N requirements.
Even better, the Spikey equipment can be purchased fitted with a hopper and auger-fed spinner specifically designed to spread fertiliser N using the patented ONEsystem. Instead of very inefficient granular urea, the state of the art ONEsystem uses wetted, nbpt urease inhibitor-treated prilled urea, reducing N application requirements literally by half, averaged over independently-conducted, scientific designed and published field trials under grazing.
