In this study, we performed monitoring of the soil solution (SS) over 10 years on a loamy/clayey-textured Dark Red Dystroferric Oxisol that received sewage sludge for agricultural purposes. The SS was obtained by lysimeters installed along the walls of a well at 1 m, 2 m, 3 m, 4 m and 5 m in depth. The major ions found in the SS were NO3-, SO42-, Cl-, Ca2+, Mg2+, Al3+, Pb2+, Cd2+ and Zn2+, and the pH level ranged from 4 to 6.5 along the profile. Throughout the first three years of monitoring, the pH to a 3-m depth became more acidic, and in the last year, this trend reached 5 m. At the 5-m depth, the pH decreased from 6.5 to 4.5 from the first to the last monitoring. The SS acidification was provoked by both nitrite oxidation and ion leaching. The leaching of H+ or the possible ion exchange/desorption of H+ due to the leached cations (Ca2+ and Mg2+) at the 4-m and 5-m depth caused the pH decrease. The ionic strength (IS) of the solution controlled the ion leaching. The sludge application increased the IS to 3 m, increasing the density of the soil charges and its ability to absorb ions. After the sludge application was completed, there was a decrease in IS of the SS as well as a decrease in ion absorption and retention abilities, which promoted leaching to greater depths. During the entire monitoring process, NO3-, Cd and Pb remained above the potability limit. |

Data on recruitment and mortality are reported for trees ~ 5 cm dbh from 257 species at the Tapajós National Forest over an eight-year period after selective logging and in a nearby unlogged control area. Recruitment increased with time after logging while mortality was very high immediately after logging due to felled and damaged trees but slowed down by year 5 after logging. In the unlogged forest, recruitment and mortality were nearly equal during the period. Both recruitment and mortality rates were higher for light-demanding species than for shade-tolerants in the logged area over the study period, but in the undisturbed forest this situation was reversed. The effect of logging on dynamics of commercial species was positive, insofar as their mortality represented less than 15% of their recruitment. In the undisturbed forest, mortality and recruitment of commercial species were in equilibrium. |
