So the 2 ways to read the stick for RFV
Measure alfalfa height match up with pre bud or post bud and read your number
Subtract 20 points for harvest loss and that will be the number you’ll have in storage.
Example if the alfalfa height reads 200 subtract 20 points so your storage number for RFV is 180
Low Lignin Varieties:
Measure alfalfa height match up with pre or post bud and read your number
Subtract 20 points for harvest loss
Add 15-20 points to adjust for low lignin
So really you just read number on stick without subtracting anything.
Example if the stick reads 200 then the RFV in storage will be 200
