A comparison of the productivity of burned and unburned portions of an abandoned native pastures was made. The harvest method was used to sample aboveground biomass at two week intervals beginning on 3 April and terminating on 7 September 1976. The harvested material was separated into green biomass, standing dead, and litter. With the exception of the first sampling date, green biomass production was substantially higher on the burned site than the unburned site. The peak standing crop of green biomass on the burned site was 216 g/m2 occurring on 12 June, compared to a maximum of 132 g/m2 on the unburned site two weeks later. Soil temperatures measured at 5, 10, and 15 cm were almost always higher on the burned sites. The resulkts suggest that the warmer soil temperature on the burned site early spring promoted a more rapid rate of growth than on the unburned site. Precipitation patterns during the growing season may be important factors in causing the higher productivity of the burned site. |
