pine bolewood production was significantly greater on IVM plots (165 m 3 /ha) than on check and PF plots (average of 113 m 3 /ha). In the 13th growing season, IVM plots had significantly less understory tree cover (51%) than checks (80%), but PF plots had the least tree cover (16%) and the most grass (5%) and forb (10%) cover. Fertilization significantly increased understory tree cover (58%) compared with that for unfertilized plots (40%), but woody vine cover was significantly less on fertilized plots (3%) than on unfertilized plots (6%). |
