  1. A TROPICAL RAINFOREST CLEARING EXPERIMENT BY BIOMASS BURNING IN THE MANAUS REGION Authors: J. A. CARVALHO JR, J. M. SANTOS, J. C. SANTOS and M. M. LEIT Journal: Atmospheric Environment Vol. 29, No. 17, pp. 2301-2309, 1995 Presenter: Mike Rosengrant

  2. Introduction • Location: Manuas Brazil • Objective: To quantify the amounts of carbon dioxide generated by the slash and burn technique. • Look at the effect that it has on the soil

  3. Methods • One hectare of land was prepared in July and was burned in November • Total Biomass was measured before burning. • Forest was Burned • Measurements were retaken and compared to the original data.

  4. Results

  5. Results • Trunks accounted for 59.5% of the dry above ground biomass. • The average carbon content of trunks was 48.4%. • The average carbon content for leaves was 50.4% • The average mass of carbon of the area was • 203.2 t ha- 1. • The gasification efficiency of the test was estimated • to be 25.1%.

  6. Discussion • Shows us how much gas these farming techniques release into the atmosphere • Looks at the impact slash and burn has on the soil
