La société américaine Harvest Tech annonce avoir mis au point un système permettant de mesurer en ligne la valeur nutritive du fourrage de Luzerne et de stocker cette information dans une puce RFID associée à chacune des balles.

L’explication par FarmIndustryNews :
« The producer takes a hay sample just before or after the field is cut, and gets a lab RFV analysis. That value is entered into the Harvest Tec system when baling begins. As the baler operates, Harvest Tec’s dual star wheel sensors take hay moisture readings 96 times every 3 seconds to achieve moisture measurement of plus or minus one percent accuracy.
Next, the baler’s scale provides bale weight accuracy within 2 percentage points. From the moisture and weight data, the Harvest Tec system calculates the dry matter density and the relative feed value of each individual bale. »
