4.2.4 Organic Carbon
As for the organic carbon dissolved in water (C), the data were higher in T1 with averages of 9.76, 10.50 and 8.55 mg 1-l, in February, October and December respectively, reaching values ​​of C above 19 mg 1-1 in 2000. In treatment T2, the average carbon values ​​of 6.25, 5.88 and 4.90 mg 1-l, for the same months, were between 4.9 and 6,2 mg 1-1 (Figure 3H) while at T1, they were between 8.5 and 10.5 mg 1-1(Figure 3G).
It ensures that the amount of C in the water after the implementation of the project was lower than the situation before the implementation of the project, in this case, the conservationist practices implemented contributed to a smaller amount of eroded sediments, a result that corroborates with Silva et al. (2005) that in their study the organic C was the constituent found in bigger quantity in eroded sediments, emphasizing the need for conservationist practices that reduce the erosive action of rain, maintaining this organic fraction in the soil.
