“…The importance of AMF in water absorption and aid to tolerance to long periods of drought is already known. This group of organisms plays a fundamental role for the maintenance of this ecosystem, considering that the Cerrado is an ecosystem, where its climate pattern presents a long semester of drought (Moura and Cabral, 2019). The values of spore density, mycorrhizal colonization rate, and easily extractable glomalin are excellent indicators of the action of AMF in the biome studied during seasonal variation.…”

“…This encompassing grasses, legumes, and tree species such as the pequi (Caryocar brasiliense) and the buriti (Mauritia flexuosa; de Miranda, 2008). Of the 79 species of AMF found in Brazilian biomes, 67% were identified in soils of the Cerrado biome, being closely linked to the edaphoclimatic conditions of the region (Moreira and Siqueira, 2006;Moura and Cabral, 2019;.…”

Purpose: Understanding the dynamics of mycorrhizal fungi in the Cerrado is fundamental for the adoption of conservation practices and for understanding the resilience of this biome in relation to long periods of drought. Thus, this work aimed to verify the dynamics of the mycorrhizal population in five phytophysiognomies of the Cerrado biome. Methods: The samples were taken from the Chapada dos Veadeiros National Park, a permanent preservation with native Cerrado vegetation without any anthropic influence. The five main phytophysiognomies of the Cerrado biome were chosen: the Campo Limpo, Campo Sujo, Cerrado Strictu Sensu, Cerradão, and Veredas. Rhizospherical soil samples were collected in both the wet and dry seasons. Spore density, mycorrhizal colonization rate, easily extractable glomalin, and associated mycorrhizal fungi genera were identified. Results: The values of spore density, mycorrhizal colonization rate, and glomalin were higher in the samples performed during the dry season compared to the samples performed in the rainy season. The same behavior was observed when comparing the different phytophysionomies. Conclusion: Mycorrhizal activity is higher in dry periods when compared to rainy periods. There is no specificity of genera of arbuscular mycorrhizal fungi within the Cerrado phytophysiognomies.

“…Cover plants are responsible for soil protection in these systems and can influence the diversity and richness of the rhizospheric microorganism community in the soil (Alguacil, 2015). Arbuscular mycorrhizal fungi (AMF) are one of the most important groups of edaphic organisms, and their activity is closely linked to plant health and can be used as a bioindicator of environmental quality in different soil management systems (Borie et al, 2006;Alguacil et al, 2008;Alguacil, 2015;Moura et al, 2017;Moura and Cabral, 2019).…”

“…Given its importance in the regional development of agriculture in the Cerrado region, understanding the biodiversity of arbuscular mycorrhizal fungi associated with the main cover crops used in conservation systems is of fundamental importance for the effective management of management practices in this region (Moura and Cabral, 2019;Aker et al, 2022;Durigan et al, 2022).…”

This study aimed to evaluate the occurrence of mycorrhizal fungi and glomalin content in soil under different cover crops with and without the application of nitrogen in the cover. The following cover plants were used: Crotalaria juncea (Crotalaria juncea L.), wild beans from Ceará (Canavalia brasiliensis Mart. ex Benth.), Guandú ‘BRS mandarin’ [Cajanus cajan (L.) Millsp.], millet ‘BR05’ [Pennisetum glaucum (L.) R.Br.] and sorghum ‘BR 304’ [Sorghum bicolor (L.) Moench]. The absolute control of the experiment was the treatment without the use of cover crops, that is, the vegetation of spontaneous occurrence in the area. The experimental design was randomized blocks in subplots with three replications. Spore density, mycorrhizal colonization rate, easily extractable glomalin, and species present in the rhizosphere of the cover crops were determined. No differences were found in the diversity of mycorrhizal fungi associated with the different cover crops studied or in the values of spore density, root colonization, or glomalin content. Nitrogen application did not influence the mycorrhizal activity in the investigated cover crops. The most frequent species associated with cover crops were Scutellospora pellucida and Scutellospora persica in C. juncea; Gigaspora sp. on Sorghum; Glomus macrocarpum in Guandu; G. macrocarpum and Glomus clavisporum in millet; and Glomus microaggregatum and Glomus tortuosum in Spontaneous Vegetation.

“…The current Brazilian scenario fits this conclusion because agribusiness can play a fundamental role in the country's economic recovery (Pacheco, 2019). In this sense, Brazil does not owe in any sense to other countries in technology and labor, being competitive in its products in quality and price, with the advantage that still has the ability to expand production and own the largest agricultural barn in the world (Moura & Cabral, 2019).…”

Impacts of Sars-Cov-2 on Brazilian Agribusiness

The pandemic caused by the Sars-Cov-2 virus has impacted several sectors of the world's economy including agribusiness. In Brazil, the quarantine decreed by political leaders in order to contain the spread of Covid-19 mainly affected the productive sectors of the medium and small producer, which ended up reflecting directly on the price of food of the final consumer. Sectors such as transportation, distribution and agro-industry should also present a deficit because they are productive activities with agglomerations of people who have had their work regimes changed. However, the extensive production sector benefited from the rising dollar and increased demand for food and exports from China, and this demand may extend in the medium and long term. There is a great possibility that agribusiness will be the sector with the largest surplus in the Brazilian economy in the coming years and be responsible for balancing the trade balance in the post-recession period.
