| Summary: | affected. I feel that even though harvesting has analyzed with a total organic carbon analyzer. Results and mineral soil respiration, along with total soil and Black method, an acid digest procedure. Soluble organic carbon content was determined from cold-water extracts community activity around the world. An increasing number of cut, and a non-harvested control. I hypothesized that data show that when temperate forests are allowed to regrow directly with soil temperature and inversely with soil every three sampling periods beginning with period 6. Total hardwood forest. Treatments included a clearcut, a partial Harvesting significantly (a=0.05) increased the amount of immediately after harvest, carbon assimilated in growing increase in live root and associated microflora activity in indicated that harvesting significantly (a=0.05) increased in land. I examined the effects of harvest intensity on in situ measure of man's impacts on the environment, including forest measuring mineral soil respiration in the lab. Soil moisture. Harvesting effects on mineral soil respiration respiration rates would vary directly with harvest intensity. Sampling occurred between 6 and 22 months after harvesting. significantly effected soil respiration rates, this increase situ respiration and the wet alkali method was used for situ respiration during most sampling periods. This effect soil organic carbon content was determined by the Walkley- Soil respiration rates have been used as an indicator of soil soluble organic carbon levels were not significantly soluble organic carbon, were examined in a bottomland studies have been performed using soil respiration rates as a temperature and moisture content were also measured. The sodalime absorption technique was used for determining in the soil following harvesting. In situ respiration varied total organic carbon in the top 15 cm, whereas overall Total soil and soluble organic carbon analyses were performed vegetation is greater than the C02 lost from the soil. was attributed to the revegetation of the site creating an were less clear and showed trends in only some months. will not adversely affect atmospheric C02 levels.
