Much of the diversity of mushrooms is still unknown to science. On the search for new edible mushrooms, we began to look at the traditions of Amazonian forest peoples in order to learn about the potential for edible mushrooms among other species. On particular, the Yanomami people launched the encyclopedia of food (Sanoma) in 2016 to preserve their knowledge of their own food. They demonstrated how food production can be balanced with the forest and present dozens of mushrooms that are consumed by their communities. On view of the above information, the objective of this work is to present bromatological aspects of the Lentinus crinitus mushroom from an agroforestry homegarden in the Cerrado. The specimen was collected from an agroforestry homegarden with biome forest species and agronomic species, located in the Brazilian Cerrado, in the city of Goiânia, Goiás. L. crinitus mushrooms presented 61% humidity, containing 14% crude protein, 1.5% ether extract, 26% crude fiber, and 3.4% mineral matter. Ots bromatological characteristics are similar to others of commercial fungi. There is great potential for the use of the Lentinus crinitus mushroom in agroforestry yards in the Brazilian Cerrado, reconciling environmental conservation with the diversification of the production of agroextractive products.

A bacia hidrográfica do rio Caldas possui área de drenagem de aproximadamente 1.288,00 km², abrange onze municípios e seu curso d’água principal é afluente do rio Meia-Ponte, um dos mananciais que abastecem Goiânia. Objetivou-se analisar: a) os conflitos de uso do solo por atividades antrópicas na bacia hidrográfica do rio Caldas, estado de Goiás, enfatizando as ocorrências destas atividades nas Áreas de Preservação Permanente (APPs) de cursos d'água, de acordo com a Lei 12.651/2012 (Código Florestal); b) o histórico da ocupação irregular das APPs para um período de 32 anos (1985 – 2017), observando se após a aprovação do Código Florestal ainda há irregularidades no uso do solo desses locais. A metodologia consistiu na consulta a documentos legais, avaliação cartográfica e na classificação de imagens de satélites para os anos de 1985, 2008, 2012 e 2017. Constatou-se que 35,903 km² são ocupados pelas APPs amostradas neste estudo, aproximadamente 2,8% da área da bacia. Para o ano de 1985 quantificou-se uma área de 30,93 km² de conflitos de uso do solo nas APPs, passando para 19,9 km² em 2008, 22,67 km² em 2012 e 17,18 km² em 2017. Pastagem foi a classe que mais ocupou áreas nas APPs em todos os anos avaliados. As alterações ocorridas na legislação após 1985 influenciaram na redução da ocupação das APPs, porém, em 2017 mais de 47% dessas áreas ainda são ocupadas ilegalmente. Os resultados mostram que as APPs estudadas sofreram intervenções antrópicas durante todo o período analisado, evidenciando o não cumprimento da legislação ambiental federal.

Agricultural use and management systems in tropical soils of the Brazilian Cerrado may directly influence its chemical properties, in the conventional cultivation systems with pastures or grains, as well as in areas with a crop-livestock-forest integration system. Thus, the objective was to evaluate the chemical attributes of the soil under different use and management systems. The research was carried out at Boa Vereda Farm, in the state of Goiás, Brazil. The experimental design was completely randomized with a 5 x 3 factorial arrangement divided into five production systems: (1) among the rows of Eucalyptus (CLFI), (2) within the rows of Eucalyptus (CLFI), (3) in conventional agricultural monoculture, (4) pasture, and (5) -natural Cerrado (control treatment). Samples were collected in three soil depths (0-0.5; 0.5-0.1 and 0.1-0.2 m), with four replicates each. Among the chemical properties of the soil studied, the organic matter, calcium, magnesium and potassium contents, base saturation, and cation exchange capacity, are higher in the soil with natural Cerrado. The area of agricultural monoculture showed the highest levels of phosphorus and copper, but has the lower levels of organic matter in the soil. The chemical properties of the soil were similar in the CLFI system, regardless of the evaluation point (within or among rows). The chemical properties of the soil evaluated were similar between the pasture cultivated in CLFI and the conventional system. Therefore, the land use and management system do not directly influence the chemical properties of the soils evaluated.

The Amazon region has shown commercial potential for native mushroom species, such as mushrooms produced by the Yanomami people, who already sell more than 10 Amazon species. Among the species collected and consumed by the Yanomami people is Favolus brasiliensis (Fr.) Fr. (Basidiomycota: Polyporaceae), which occurs naturally in tropical areas of Central and South America. Thus, the objective of this work is to carry out the bromatological characterization of F. brasiliensis, contributing to a better understanding of the nutritional and food potential, as well as registering the natural occurrence of the species in the Cerrado biome and in the state of Goiás. The F. brasiliensis mushrooms collected in the present study showed an average of 7.4% humidity, 27% crude protein, 1.5% ether extract, 17% crude fiber, and 1.7% mineral matter. Compared with other species of edible mushrooms, both wild and cultivated, the moisture content of F. brasiliensis (93.60%) is low for species of the genus Pleurotus. For example, the humidity varies from 87% to more than 90%, similar to that found in Lentinus crinitus, another mushroom native to Brazil and also consumed by the Yanomami people. Thus, F. brasiliensis has the potential to be used in human foods.
