Resumo: |
The main natural process that opposes the global warming is called carbon sequestration, a phenomenon that essentially seeks to establish a dynamic equilibrium between the emission of greenhouse gas from the immobilization of the elements, especially the C and N. The present work sought to evaluate the C and N stocks in soils of the semiarid region, more specifically in the municipality of Santana do Seridó / RN, under 4 different uses: native Caatinga vegetation; palm farming irrigated with Treated WasteWater(TWW); tomato agriculture irrigated with surface water; and tomato farming in the rainfed regime, considering that the reuse of TWW for agriculture is an alternative that can mitigate the emerging problems of water scarcity in the region and also capable of influencing the ability to accumulate C, N and other nutrients in the region. soil due to its organic load. The study showed that among the evaluated areas the highest concentration of C in the soil is in the Caatinga due to the accumulation of litter, not detecting influence of the irrigation with TWW or surface water on the C and N stocks in the soil, concluding that the waste of vegetation is the main contributor to carbon storage in the studied soils. |
