Technical Note: Mineral content of guajillo regrowth following roller choppingFulbright, T. E.; Reynolds, J. P.; Beasom, S. L.; Demarais, S. (Society for Range Management, 1991-09-01)Guajillo (Acacia berlandieri Benth.) is browsed by white-tailed deer (Odocoileus virginianus Raf.). We determined phosphorus (P), potassium, (K), calcium (Ca), and magnesium (Mg) of browse from roller-chopped (July 1986 and July 1987) and nontreated guajillo. Browse from regrowth was temporarily higher in P than browse from nontreated plants. Potassium was higher in leaves from plants roller chopped in 1987. Calcium and Mg tended to be lower in leaves from roller-chopped plants. Roller chopping temporarily increases P and K, but whether or not browse from roller-chopped guajillo meets P and K requirements for deer is unknown.
