This study aimed to evaluate the effects of sewage sludge biosolids, Azospirillum brasilense, and mineral fertilization on the production of seedlings of five native tree species from the Atlantic Forest, Brazil (Cupania vernalis Cambess.; Pterogyne nitens Tull.; Psidium cattleyanum Sabine.; Eugenia uniflora L.; and Cedrela fissilis Vell.). For each species, a completely randomized design (CRD) was used, consisting of 12 treatments with seven replicates: 3 doses of biosolids in the substrate (0, 10, and 20%) combined with 2 Azospirillum treatments (Azospirillum with and without) and 2 mineral fertilization treatments (fertilization with and without). At 30, 60, and 120 days after transplanting (DAT), shoot height and collar diameter measurements were taken. At 120 DAT, chlorophyll a and b indices were analyzed, leaf, stem, and root dry mass production was determined, and morphological indices (diameter/height ratio, root/shoot ratio, and Dickson quality index) were calculated. All five species responded positively to mineral fertilization. The dose of 10% biosolids was the best for the seedling’s growth and quality, with this effect being more pronounced without the mineral fertilizer supply. The dose of 20% biosolids affected both positively and negatively the growth and quality of the seedlings; the negative effect was more evident in the treatment with 20% biosolids + Azospirillum + mineral fertilization. Azospirillum brasilense tended to increase the growth and quality of the seedlings of the five studied species, mainly in treatments without and with 10% biosolids. Still, these effects depended on the measured variable and studied species. Biosolids increased the macronutrient contents, particularly Mg followed by P, and decreased the micronutrient contents, especially Mn, in the plant shoot and roots.

ST. HIL.)” Autor: PINTO, EDUARDO LUIZ COSTA TOBIAS Primeiro orientador: Ávila, Fabrício William de Abstract: Yerba mate (Ilex paraguariensis A. St. Hil.) naturally develops in acidic soils rich in aluminum (Al). Proper management of mineral fertilization is crucial for the initial development of yerba mate. Additionally, mycorrhizae can enhance the early growth of native forest species. This study aimed to evaluate the effects of mycorrhizal inoculation, mineral fertilization, and aluminum (Al) supply on the initial development of yerba mate. In the first experiment (Chapter I), treatments consisted of mycorrhizal fungi inoculation (with and without mycorrhizae) combined with different types and doses of mineral fertilization (controlled-release NPK fertilizer and nutrient solutions containing different doses of N, P, and K). In the second experiment (Chapter II), two substrate fertilization treatments (with and without fertilization) and seven doses of Al applied monthly to the substrate were evaluated. Plant growth assessments included measurements of shoot height and stem diameter at different times, as well as determinations of dry shoot and root mass, fresh root volume, and the Dickson quality index (DQI). Complete NPK fertilization provided in a nutrient solution resulted in the highest growth of yerba mate seedlings, followed by moderate doses of controlled-release NPK fertilization. Mycorrhizal inoculation increased the growth of yerba mate seedlings. Yerba mate seedlings exhibited high tolerance to Al in the substrate, withstanding monthly applications of up to 1000 mg dm-3 of Al3+ without showing toxicity symptoms. However, doses exceeding 2000 mg dm-3 of Al3+ caused toxic effects on yerba mate seedlings. This study concludes that Al does not benefit the initial growth of yerba mate. Nonetheless, proper mineral fertilization management, combined with mycorrhizal inoculation, promotes better initial development of yerba mate.

To promote healthy cities, it is essential that all people have access to green spaces, regardless of their social context, making cities more just socio-environmentally. Thus, the objective of this study is to demonstrate the characteristics of socio-environmental justice in access to public green spaces in the city of Irati, Paraná, and their relationship with public health variables. The research assessed socio-environmental justice in Irati using the 3-30-300 rule, considering public, private, and potential green areas. Using cartographic data, vector files of the urban forest and hydrographic network were generated, and neighborhoods were compared in terms of socio-environmental justice. A sample of 2.5% of residential points were inventoried, excluding businesses, commercial establishments, and public buildings. The analysis was conducted in QGIS, applying weights to criteria through the Analytical Hierarchy Process (AHP). The Kernel density index spatialized the results, and a Cluster Dendrogram classified neighborhoods into justice categories (optimal, fair, poor). Additionally, Urban Heat Island (UHI) and Urban Thermal Field Variance Index (UTFVI) maps allowed for the correlation of socio-environmental and climate justice, with analyses performed in RStudio. The second chapter investigated the relationship between public health, green areas, and UHI. Data from E-SUS (July 1, 2022, to July 1, 2023) were used, considering diagnoses of diseases associated with climate change. Maps of green areas and UHI were generated in QGIS, while the spatial distribution of diseases was analyzed using Kernel density. Socioeconomic indicators (number of permanent residents and average income) were obtained from the 2010 IBGE census and organized by census sectors. Accessibility to primary healthcare units was assessed using an 800 m buffer. The correlation between UHI, green areas, and public health was analyzed using the Mann-Kendall test in RStudio. The results indicate that adopting the 3-30-300-Potential guideline for Irati’s current socio-environmental scenario is necessary to foster discussions on implementing new public green areas that ensure environmental equity, promote accessibility to green spaces, and improve urban population quality of life. These insights are valuable for urban managers in formulating public policies that support more resilient and healthier cities. The results also showed that diseases intensified by climate change correlate with green areas. Furthermore, the study revealed that people with higher incomes have greater access to public green spaces. It was concluded that public policies for basic healthcare services and socio-environmental equity are needed to mitigate the impacts of climate boiling. Overall, it became evident that Irati lacks public policies ensuring the creation of public green spaces to promote socio-environmental justice and more universal public healthcare policies.

However, in the period from 2016 to 2021, Brazil has been experiencing fluctuations in the productivity of the genera Pinus and Eucalyptus. In 2020, the average eucalyptus productivity was 36.8 m³.ha-1.year-1, a value 4.6% lower than the productivity in 2019. Interference by weed in commercial eucalyptus plantations has been one of the main causes which limit forest productivity, significantly reducing the volume of wood per hectare. The use of drones and remote sensing techniques are important tools for mapping weed and directing more assertive controls. In this sense, this work aims to understand the possible effects of the interaction of weed in commercial plantation of two eucalyptus clones, as well as evaluating the efficiency of applying a vegetation index in drone images to identify areas with existing weeds. The SaviGreen vegetation index made it possible to identify patches of weeds found in eucalyptus plantation up to 4 months of age. With the application of precision forestry concepts, weed control costs can be reduced. The main weed families found in the study area were Phyllanthaceae, Rubiaceae, Poaceae and Asteraceae. The most common species were erva-quente (Spermacoce latifolia) and brachiaria (Urochloa decumbens). Regardless of the clone, at 6 months of age nutritional deficiencies of N, P, K, Ca, Mg and S were identified. At 12 months the deficiencies were recovered, except for Mg. Both clones produced reductions of more than 35% in volume over bark and 40% in stem biomass when in contact with weed after 12 months of planting. Eucalyptus clones with slow initial growth, when coexisting with weed, present greater losses to growth in height, CBH, volume and stem biomass up to 15 months post-planting in relation to the clone with rapid initial growth.
