Subsoiling operation reduces the problems caused by compression; however, it is necessary to know its location and intensity. Accordingly, the aim of this work is to present a compression diagnostic method based on soil resistance to penetration as the parameter that indicates need for intervention in the subsoil. Measurements of penetration resistance was carried out in areas of sugarcane, located in the municipalities of Goianésia, Barro Alto and Santa Isabel, in the Brazilian state of Goiás. The Falker penetrometer (PLG 1020) was used, adjusted to a maximum depth of 40 cm and adopted as a critical resistance value of 4.0 MPa. The data were interpolated using kriging and adjusted in AutoCAD 2013 (Autodesk). The methodology proved effective in areas of compacted soil, and the surface layer had less resistance. The reduction in soil preparation was 96.54% and when considering the topographic adjustments, the reduction was 74.07%, showing the viability and importance of the diagnosis to show the proper management. Sugarcane (Saccharum officinarum) is one of the most important crops for the global economy. It is a valuable source of income, employment and supports economic development 1,2. In the Brazilian socioeconomic scenario, sugarcane occupies a remarkable position. Brazil is the world's largest producer of this raw material, which is the primary industrial input to produce sugar 3,4. Moreover, it is also used in the production of ethanol, used as biofuel, and utilized as biomass production for renewable energy 5. Because of its importance to the national economy, sugarcane production has expanded into almost all Brazilian states and biomes. The data was collected in the Brazilian State of Goiás, located in the Cerrado biome. The Cerrado is the second largest Brazilian biome, extending over an area of 2,045,064 km 2 6,7. Only the Amazon surpasses the Cerrado in terms of total area. Currently, the Cerrado is considered to be the last agricultural frontier in the Americas 8-12. Within this context, Goiás stands out as a state of central importance, due to the expansion of its planted area, as well as its increasing production and productivity 4,13. In the municipality of Goianésia, for instance, sugarcane cultivation began in the late 1960s. Nowadays, it is one of the region's most important agro-industrial activities, and the local economy benefits through higher tax revenues and job creation 14. The most important sugarcane varieties originate from Oceania (New Guinea) and Asia (India and China), whereas the cultivated varieties in Brazil and the world are multispecific hybrids 15. Belonging to the Poaceae family and to the class of monocotyledons, sugarcane has a long life-cycle with a span of 5-7 years 2. Some of its main characteristics are barb type inflorescence, stem growth in culms, leaves with silica blades on their edges and an open hem 15. In spite of the long life-cycle of sugarcane, an important feature is the sufficient development of its root system 2 because it provides increased productivity of culms 16 , which are the parts of greater commercial interest. Root system development may be limited by the physical conditions of soil, especially regarding compression. Soil compression increases resistance to the plant's root development and consequently decreases agricultural productivity 17 .

Our work presents the nutritional aspects of two mushroom species found in an agroforestry system in the Cerrado (Auricularia nigricans and Schizophyllum commune), and a morphological identification key for the edible mushroom species highlighted in this study. The nutritional composition analysis revealed a moisture content of 65 and 41%, proteins of 7 and 10%, ether extract (fat) of 1.3 and 1.5% and fiber of 2 and 2.2% for A. nigricans and S. common, respectively. In this work we highlight the nutritional potential of two species of edible mushrooms, A. nigricans and S. commune. These mushrooms show similar nutritional characteristics to those of commercially produced exotic mushrooms, being rich in proteins and minerals. These data, added to other reports of this nature recently presented, reinforce the importance of knowledge of local biodiversity and native mushrooms as a food source.

One of the main agricultural activities in the region is high-tech livestock. Cerrado soils are predominantly low in fertility, and arbuscular mycorrhizal fungi play a fundamental role in plant nutrition in this biome. Understanding the behavior of mycorrhizal fungi in the soil under pasture is essential for the development of more efficient and sustainable management practices. Thus, this work aims to verify the activity of arbuscular mycorrhizal fungi in different species of forage grasses cultivated in cerrado soil. To measure mycorrhizal activity, soil spore density factors and mycorrhizal colonization rates in roots of 14 forage grass genotypes were investigated. No significant differences were identified in spore density values between the investigated genotypes. Panicum maximum cv and Mombasa showed the lowest values of mycorrhizal colonization, and the highest values were found in the roots of Brachiaria decumbens. Among the identified genera associated with the rhizosphere of the genotypes studied, Gigaspora, Scutelospora and Sclerocysts are less frequent, which indicates that the association with these fungal genera is less recurrent than with the others.

The objective is to analyze the conceptual and defining parameters of bioinputs, going into sustainable aspects and outlining an overview of the beneficial points when compared to pesticides. Based on the definitions presented, the study focuses on the following question: Are there laws in Brazil that regulate the use and manufacture of bioinputs in view of the exponential growth of the productive market? To answer the central question, the research makes use of the qualitative method that guided the search for bills in progress regarding the theme and enabled the analysis of the viability of the contents presented. As a result, the effectiveness of bioinputs as agents to combat pests is demonstrated, being an environmentally sustainable resource with demonstrated efficacy. Thus, with the demonstration of beneficial implications in management, a legislative gap is identified that permeates the production of bioinputs, including on-farm production, which reflects the lack of regulation regarding production, registration and especially supervision. Although the National Bioinputs Program is in force, laws need to be created from a regular legislative process aimed at regulating the sector that is in notorious growth, which demonstrates the need for the analysis of Bills 3668/21 and PL658/21, currently being processed in the Brazilian legislature.

The objective of this study is to show coprocessing in cement production as a viable means of final disposal of waste generated in the industrialization process, together with urban solids, as an efficient method for complying with the new national solid waste policy. A study was conducted on the introduction of the coprocessing approach focusing on the materials that integrate the process, the heat capacity of the solid waste used and the savings generated by this strategy in terms of nonrenewable fossil fuels. The proposed methodology involved a systematic review of the literature in the last fifteen years. The results show that millions of tons of waste are coprocessed every year. It is concluded that coprocessing is a viable alternative for waste reduction.

As it is an easy-tomanage crop, it can be grown in small areas and does not require high soil fertility. This culture has a symbiotic relationship with arbuscular mycorrhizal fungi (AMF), which expand the extent of the roots by the projection of their hyphae, which favors the absorption of water and nutrients from the soil and with nitrogen-fixing bacteria. The objective of this work was to evaluate the interaction of nitrogen-fixing bacteria with arbuscular mycorrhizal fungi at the initial stage of cassava culture. The following parameters were evaluated: the day of sprouting, plant height, root length, plant volume, colonization rate of mycorrhizal fungi and the genera of arbuscular mycorrhizal fungi. Plants inoculated with AMF and diazotrophic bacteria presented the lowest day of sprouting, the highest plant height and longer root length. Mycorrhizal interactions with and without inoculation with nitrogen-fixing bacteria were classified, and mycorrhizal fungi of the genera Acaulospora, Diversispora, Glomus and Gigaspora were classified. Resumo A mandioca é um importante alimento na base alimentar, ótima fonte alternativa de carboidratos, especialmente em países em desenvolvimento. Por ser uma cultura de fácil manejo, pode ser cultivada em pequenas áreas e não exige alta fertilidade do solo. Esta cultura possui relação simbiótica com fungos micorrízicos arbusculares (FMA), que ampliam a extensão das raízes pela projeção de suas hifas, o que favorece a absorção de água e nutrientes do solo e com bactérias fixadoras de nitrogênio. O objetivo com este trabalho foi avaliar a interação das bactérias fixadoras de nitrogênio com os fungos micorrízicos arbusculares no estádio inicial da cultura da mandioca. Foram avaliados: o dia da brotação, altura da planta, comprimento das raízes, volume da planta, a taxa de colonização dos fungos micorrízicos e foram classificados os gêneros dos fungos micorrízicos arbusculares. As plantas inoculadas com FMA e bactérias diazotróficas apresentaram o menor dia da brotação, a maior altura da planta e maior comprimento de raízes. Houve interação micorrízica com e sem inoculação com bactérias fixadoras de nitrogênio e foram classificados fungos micorrízicos dos gêneros: Acaulospora, Diversispora, Glomus e Gigaspora.

The dredging is the most efficient management practice in the correction of soil acidity and increase of base saturation levels. The nickel iron mining scora is a residue that has relevant amounts of magnesium silicate, and may have neutralization capacity of soil acidity. Therefore, the objective of this work was to value the potential of magnesium silicate as a soil acidity corrective. The experimental design used was completely randomized, arranged in a 2x5x5 factorial scheme with twelve replications, where the 1st factor consisted of two hatching dates, 30 and 60 days, the 2nd factor consisted of five doses of mining slag: 0, 90, 120, 150 and 180 Mg ha-1, and the 3rd factor consisted of five doses of dolomític limestone: 0, 90, 120, 150 and 180 Mg ha-1. The mining slag did not present soil pH neutralization power under the evaluated conditions. However, it presented potential for neutralization under conditions of lower granulometry and greater solubilization.

Em contrapartida, há uma grande demanda pela retirada parcial ou integral dessa palha devido seu grande potencial energético e calorífico, o que pode aumentar significativamente a produção da bioenergia e do etanol de segunda geração. Objetivou-se com este trabalho avaliar a taxa de decomposição da palha de cana de açúcar, a economia gerada pelo retorno dos nutrientes ao solo pela mineralização, e seu potencial de geração de etanol de 2° geração (E2G). O potencial econômico pela produção de etanol foi avaliado pelos dados comparativos de 3 quantidades de palhada deixada sobre o solo no decorrer de uma safra correlacionando com tabelas de mineralização disponíveis na literatura e confrontando com o potencial de produzir E2G. Para este estudo, considerou-se três diferentes cenários para analisar o retorno econômico da manutenção ou retirada da palhada. Para determinação das taxas de decomposição foram utilizadas três diferentes quantidades de palha (10,6, 16 e 32 Mg ha-1). Observou-se que, em média, a palhada de cana-de-açúcar mantida sobre o solo apresenta taxa de decomposição de 13% da massa seca. Observou-se ainda, que quando mantida, há uma economia em relação a aplicação de fertilizantes para reposição de nutrientes após um ciclo de cultivo. Já quando a palhada é retirada e utilizada para produção de E2G, o retorno econômico pode ser até dezessete vezes maior do que quando deixada sobre o solo.

Sugarcane (Saccharum officinarum) is one of the most important crops for the global economy. It is a valuable source of income, employment and supports economic development 1,2. In the Brazilian socioeconomic scenario, sugarcane occupies a remarkable position. Brazil is the world's largest producer of this raw material, which is the primary industrial input to produce sugar 3,4.

Because of its importance to the national economy, sugarcane production has expanded into almost all Brazilian states and biomes. The data was collected in the Brazilian State of Goiás, located in the Cerrado biome. The Cerrado is the second largest Brazilian biome, extending over an area of 2,045,064 km 2 6,7. Only the Amazon surpasses the Cerrado in terms of total area. Currently, the Cerrado is considered to be the last agricultural frontier in the Americas 8-12. Within this context, Goiás stands out as a state of central importance, due to the expansion of its planted area, as well as its increasing production and productivity 4,13. In the municipality of Goianésia, for instance, sugarcane cultivation began in the late 1960s. Nowadays, it is one of the region's most important agro-industrial activities, and the local economy benefits through higher tax revenues and job creation 14. The most important sugarcane varieties originate from Oceania (New Guinea) and Asia (India and China), whereas the cultivated varieties in Brazil and the world are multispecific hybrids 15. Belonging to the Poaceae family and to the class of monocotyledons, sugarcane has a long life-cycle with a span of 5-7 years 2. Some of its main characteristics are barb type inflorescence, stem growth in culms, leaves with silica blades on their edges and an open hem 15. In spite of the long life-cycle of sugarcane, an important feature is the sufficient development of its root system 2 because it provides increased productivity of culms 16 , which are the parts of greater commercial interest. Root system development may be limited by the physical conditions of soil, especially regarding compression. Soil compression increases resistance to the plant's root development and consequently decreases agricultural productivity 17 .

One of the main agricultural activities in the region is high-tech livestock. Cerrado soils are predominantly low in fertility, and arbuscular mycorrhizal fungi play a fundamental role in plant nutrition in this biome. Understanding the behavior of mycorrhizal fungi in the soil under pasture is essential for the development of more efficient and sustainable management practices. Thus, this work aims to verify the activity of arbuscular mycorrhizal fungi in different species of forage grasses cultivated in cerrado soil. To measure mycorrhizal activity, soil spore density factors and mycorrhizal colonization rates in roots of 14 forage grass genotypes were investigated. No significant differences were identified in spore density values between the investigated genotypes. Panicum maximum cv and Mombasa showed the lowest values of mycorrhizal colonization, and the highest values were found in the roots of Brachiaria decumbens. Among the identified genera associated with the rhizosphere of the genotypes studied, Gigaspora, Scutelospora and Sclerocysts are less frequent, which indicates that the association with these fungal genera is less recurrent than with the others.

The objective is to analyze the conceptual and defining parameters of bioinputs, going into sustainable aspects and outlining an overview of the beneficial points when compared to pesticides. Based on the definitions presented, the study focuses on the following question: Are there laws in Brazil that regulate the use and manufacture of bioinputs in view of the exponential growth of the productive market? To answer the central question, the research makes use of the qualitative method that guided the search for bills in progress regarding the theme and enabled the analysis of the viability of the contents presented. As a result, the effectiveness of bioinputs as agents to combat pests is demonstrated, being an environmentally sustainable resource with demonstrated efficacy. Thus, with the demonstration of beneficial implications in management, a legislative gap is identified that permeates the production of bioinputs, including on-farm production, which reflects the lack of regulation regarding production, registration and especially supervision. Although the National Bioinputs Program is in force, laws need to be created from a regular legislative process aimed at regulating the sector that is in notorious growth, which demonstrates the need for the analysis of Bills 3668/21 and PL658/21, currently being processed in the Brazilian legislature.

As it is an easy-tomanage crop, it can be grown in small areas and does not require high soil fertility. This culture has a symbiotic relationship with arbuscular mycorrhizal fungi (AMF), which expand the extent of the roots by the projection of their hyphae, which favors the absorption of water and nutrients from the soil and with nitrogen-fixing bacteria. The objective of this work was to evaluate the interaction of nitrogen-fixing bacteria with arbuscular mycorrhizal fungi at the initial stage of cassava culture. The following parameters were evaluated: the day of sprouting, plant height, root length, plant volume, colonization rate of mycorrhizal fungi and the genera of arbuscular mycorrhizal fungi. Plants inoculated with AMF and diazotrophic bacteria presented the lowest day of sprouting, the highest plant height and longer root length. Mycorrhizal interactions with and without inoculation with nitrogen-fixing bacteria were classified, and mycorrhizal fungi of the genera Acaulospora, Diversispora, Glomus and Gigaspora were classified. Resumo A mandioca é um importante alimento na base alimentar, ótima fonte alternativa de carboidratos, especialmente em países em desenvolvimento. Por ser uma cultura de fácil manejo, pode ser cultivada em pequenas áreas e não exige alta fertilidade do solo. Esta cultura possui relação simbiótica com fungos micorrízicos arbusculares (FMA), que ampliam a extensão das raízes pela projeção de suas hifas, o que favorece a absorção de água e nutrientes do solo e com bactérias fixadoras de nitrogênio. O objetivo com este trabalho foi avaliar a interação das bactérias fixadoras de nitrogênio com os fungos micorrízicos arbusculares no estádio inicial da cultura da mandioca. Foram avaliados: o dia da brotação, altura da planta, comprimento das raízes, volume da planta, a taxa de colonização dos fungos micorrízicos e foram classificados os gêneros dos fungos micorrízicos arbusculares. As plantas inoculadas com FMA e bactérias diazotróficas apresentaram o menor dia da brotação, a maior altura da planta e maior comprimento de raízes. Houve interação micorrízica com e sem inoculação com bactérias fixadoras de nitrogênio e foram classificados fungos micorrízicos dos gêneros: Acaulospora, Diversispora, Glomus e Gigaspora.

The dredging is the most efficient management practice in the correction of soil acidity and increase of base saturation levels. The nickel iron mining scora is a residue that has relevant amounts of magnesium silicate, and may have neutralization capacity of soil acidity. Therefore, the objective of this work was to value the potential of magnesium silicate as a soil acidity corrective. The experimental design used was completely randomized, arranged in a 2x5x5 factorial scheme with twelve replications, where the 1st factor consisted of two hatching dates, 30 and 60 days, the 2nd factor consisted of five doses of mining slag: 0, 90, 120, 150 and 180 Mg ha-1, and the 3rd factor consisted of five doses of dolomític limestone: 0, 90, 120, 150 and 180 Mg ha-1. The mining slag did not present soil pH neutralization power under the evaluated conditions. However, it presented potential for neutralization under conditions of lower granulometry and greater solubilization.

Em contrapartida, há uma grande demanda pela retirada parcial ou integral dessa palha devido seu grande potencial energético e calorífico, o que pode aumentar significativamente a produção da bioenergia e do etanol de segunda geração. Objetivou-se com este trabalho avaliar a taxa de decomposição da palha de cana de açúcar, a economia gerada pelo retorno dos nutrientes ao solo pela mineralização, e seu potencial de geração de etanol de 2° geração (E2G). O potencial econômico pela produção de etanol foi avaliado pelos dados comparativos de 3 quantidades de palhada deixada sobre o solo no decorrer de uma safra correlacionando com tabelas de mineralização disponíveis na literatura e confrontando com o potencial de produzir E2G. Para este estudo, considerou-se três diferentes cenários para analisar o retorno econômico da manutenção ou retirada da palhada. Para determinação das taxas de decomposição foram utilizadas três diferentes quantidades de palha (10,6, 16 e 32 Mg ha-1). Observou-se que, em média, a palhada de cana-de-açúcar mantida sobre o solo apresenta taxa de decomposição de 13% da massa seca. Observou-se ainda, que quando mantida, há uma economia em relação a aplicação de fertilizantes para reposição de nutrientes após um ciclo de cultivo. Já quando a palhada é retirada e utilizada para produção de E2G, o retorno econômico pode ser até dezessete vezes maior do que quando deixada sobre o solo.
