at 10 pounds per 1000 you ARE just fertilizing, it has little to no pre emergent capability at that rate
If you ever see it in a feed mill it has to be 60% protein minimum to be effective as a pre-M, the suggested rate by Iowa state Univ. is 20 pounds per 1000 minimum, their testing went all the way up to 80 Lbs per 1000 YIKES!
