This new grass monitor mounts on top of a boot and uses ultrasound sensors to automatically measure and track grass growth as you go about your field chores. Knowing how much growth there is lets you know how much feed value there is, and can help you do a better job of managing your pastures throughout the growing season, says the company.

The Grassometer from Mole Valley Farmers, a farmer’s cooperative in England, uses 4 ultrasound sensors. They automatically take thousands of grass height and density measurements across the pasture as you walk, and instantaneously calculate the kilograms of dry matter per hectare.The readings are instantly shown on a digital display. The unit can also relay the information back to your smartphone or computer. The company says the unit is especially useful for anyone using a rotational grazing system. It sells for about $2,700.
