“…The pH increased (from 5.10 to 5.85), showing a reduction in acidity. In degraded areas, the reduction in soil acidity led to bene ts such as a decrease in the mobilization of toxic elements such as aluminum, arsenic (Guimarães et al, 2017) and magnesium (Teran et al, 2020). pH between 5.8 to 6.2 is an optimal range promoting availability of essential nutrients for the plant.…”

Areas undergoing forest restoration need to be monitored to achieve ecosystem services. This work was carried out to evaluate the establishment of the riparian forest area in the restoration process, after 18 years of intervention, through temporal analysis of the landscape, biotic and soil indicators. Moreover, a temporal analysis of the landscape, biomass and Gross Primary Production (GPP) was carried out, via geoprocessing, at five-intervals within the period from 2002 to 2020, as well as biotic indicators (seed rain, seed bank, seedlings), and edaphic indicators from 2019 to 2020. The seed rain presented 1,197 propagules, belonging to 27 different species. The soil seed bank showed higher density in the rainy season (21.3 seeds/m2), 25 seeds, seven species, and only one botanical family recorded. In the seedling bank, 1,193 seedlings were reported, belonging to 28 botanical families, in which 57% of the individuals are arboreal-shrubby of the forest. Edaphic conditions improved compared to the initial project implementation. In 2010 using the temporal analysis of the landscape, the planting area was 100% covered with dense vegetation. For biomass and the GPP is a linear increment over time. The successional stage of the area is advanced, with a significant representation of secondary and climax species. The monitoring favored understanding the dynamics of the restoration environment and conservation.

The use of sewage sludge in soil is a environmentally sustainable practice, compatible with the Brazilian Policy of Solid Wastes. Due to its content of organic compounds and nutrients, the sludge is beneficial to the physical, chemical and biological soil properties and to the development of plants. However, since it may contain chemical and microbiological pollutants, it has to be carefully used by following criteria and procedures concerning the protection of the environment and public health. In 2020, Brazil approved Resolution 498 of CONAMA for the definition of criteria and procedures for production and application of biosolids in soil. Besides its agricultural use, this Resolution covers other uses, such as the recuperation of degraded areas. For the use of sludge on land, it needs to be processed in a Sludge Management Unit licensed by a local environmental agency. Depending on the criteria in the Resolution, biosolids are classified under Classes A and B for their microbiological quality, and under Classes 1 and 2 for their chemical aspects.
