Speedy sampling of grass dry matter yield comes from the Feed Reader. Developed in New Zealand and offered here by Agricultural Supply Services, this mobile unit mounts on an ATV and can work at up to 32km/hr; crop height is read by a separate forward-mounted ultrasonic head. Data interchange with a PC means that fields can be pre-loaded and yield maps passed back. Three levels of functionality are offered, starting at £2,250 for basic dry matter measurement.
