| 520 | _aThe standing stocks and fluxes of nitrogen were measured for four years in an experimental slash and burn agricultural site and control forest in the Amazon Basin of Venezuela. During the study, there was a decrease of about 15% in nitrogen in the system as a whole due to leaching, harvesting, and denitrification. However, nitrogen levels in the soil did not change, due to replenishment by nitrogen entering the soil from decomposing slash. Since nitrogen levels in the soil remained high, scarcity of nitrogen is probably not responsible for the observed decline in crop yields, and lack of nitrogen is not expected to affect secondary succession in the abandoned agricultural plot. | ||
