“…De maneira geral, em todos os GD não houve diferenças significativas entre as alturas de plantas dos sistemas de plantio em sulco (cultivo mínimo) e o sistema de plantio convencional. Os sistemas em sulco e convencional podem ter promovido menores alturas de plantas devido ao elevado revolvimento da camada superficial do solo, que por consequencia promove uma maior compactação superficial, favorecendo a degradação do solo e a perda da qualidade microbiologica (LLANILLO et al, 2006;RÓS;TAVARES FILHO;BARBOSA, 2014). A aplicação da adubação biológica não promoveu alterações na altura de plantas.…”

“…No sistema de plantio convencional o solo é prontamente revolvido, promovendo alteração na agregação das partículas, principalmente das argilas, que retém a maior parte dos nutrientes necessários às plantas (LLANILLO et al, 2006). Com o processo de inversão das leivas, enterrase a cobertura vegetal, deixando a superfície do solo totalmente exposta a intempéries, o que consequentemente promoverá uma maior evaporação da água armazenada no solo, além de um maior arraste das partículas pela ação da chuva e do vento (SILVA et al, 2015).…”

A fase de implantação do cafeeiro consiste em uma das etapas mais importantes da cultura. Vale ressaltar, que os diferentes sistemas de implantação proporcionam condições distintas de desenvolvimento das culturas. Além disso, visando um bom desenvolvimento inicial do cafeeiro, os produtores têm aplicado em lavouras recém-transplantadas adubos biológicos, que têm como vantagem a melhora da biota do solo, além da redução de custos com a aquisição de fertilizantes minerais. Poucas pesquisas têm testado de forma conjunta a eficiência dos diferentes sistemas de implantação e a adubação biológica no cafeeiro. Assim, objetivou-se testar a eficácia de diferentes tipos de plantio e do fertilizante biológico no crescimento inicial do cafeeiro arábica, cultivar Catucaí, em função do índice térmico. O experimento foi desenvolvido no Sul de Minas Gerais, Brasil. O delineamento experimental foi em blocos casualizados, em esquema fatorial 3 x 2 com 4 repetições, num total de 6 tratamentos. Foram utilizados: a) três sistemas de implantação (plantio convencional, o plantio direto na cova e cultivo mínimo); e b) duas doses do adubo biológico (presença e ausência). Foram avaliados os parâmetros de crescimento e a primeira safra do cafeeiro. As avaliações foram realizadas em função dos graus dias contabilizados a partir da data de plantio. Os resultados foram submetidos à análise de variância e as médias agrupadas pelo teste de Scott-Knott. As plantas de café implantadas no sistema de plantio “em covas” evidenciaram os melhores resultados, tanto nos parâmetros vegetativos como na produtividade. A utilização da adubação biológica no cafeeiro arábica recém-transplantado não promoveu melhorias no crescimento vegetativo e primeira produção do cafeeiro.

“…These trends show a significant uptake of NT yet a restrained use of CA, not reaching the desired level for sustainable agriculture standards. The growth in CA from 2006 to 2017, while notable, remains limited due to several factors: (i) the often-delayed economic return from CA, with rural producers typically favoring systems that provide immediate profits [15]; (ii) a tendency to favor simpler production systems that focus on crop succession rather than rotation [16,17]; (iii) farmers being confined to growing the predominant grain of their region due to logistics, infrastructure, and market considerations, deterring them from diversifying crops [18,19]; and (iv) the dominance of crops like cassava or sugarcane in some regions, as opposed to grain [20,21] (Table 2).…”

“…In southern Brazil, sugarcane, beans, and tobacco cultivation contribute substantially to the persistence of traditional soil tillage practices, as conventional tillage. These crops present technical barriers to modifying soil management techniques and are often grown in landscapes that hinder the deployment of farm machinery and equipment [4,20].…”

Brazil, the development of a strong technical foundation for soil and water conservation has made no-tillage (NT) the leading method for preparing land for temporary crops. Despite this, there's insufficient information regarding the extent to which farmers have adopted NT and conservation agriculture (CA) and the distribution and evolution of these practices within Paraná-a state at the forefront of NT and CA implementation. This study investigates the adoption rates of NT and CA among Paraná's farmers, focusing on temporary crops. It utilizes specialized data from the Brazilian Institute of Geography and Statistics' agricultural censuses of 2006 and 2017. Adoption rates for NT and CA were determined by comparing their proportions in both the number of farming properties and the overall land area devoted to temporary crops across various microregions. Findings indicate a rise in the adoption of NT from 68.5% to 78.9% and CA from 14.6% to 27.7% over the 2006 to 2017 period. Moreover, adoption rates varied across the 39 microregions, with the highest rates in regions dominated by temporary crops, particularly soybeans, maize, and wheat. Conversely, the lowest adoption rates were found in microregions where permanent crops and pastures prevailed, and sugarcane, cassava, and rice were the primary temporary crops.

“…Brazil was one of the earliest adopters of no‐tillage and crop rotation (Fuentes‐Llanillo et al., 2013). Conservation practices in the country require farmers to maintain plant residues from preceding crops on the soil surface, guaranteeing cover and protection against erosion (Didoné et al., 2014; Didoné et al., 2015; Telles et al., 2019).…”

Conservation practices preserve soil quality and may also increase the value of agricultural land. The economic benefits of conservation practices include increased agricultural yields, decreased risk of production losses from weather events, decreased number of farming operations, simplification of farm management, and decreased production costs. We analyze the links between soil conservation practices and the value of agricultural lands. The soil conservation practices considered in this study include no-tillage, crop rotation, contour farming, and the use of agricultural terraces. We use municipal data on annual crops in the state of Paraná from the 2006 Brazilian Census of Agriculture. Results show that the average value of lands under conventional tillage is between 10 and 22% lower than lands under no-tillage, ceteris paribus. The economic benefits of adopting no-tillage can be maximized when performed in conjunction with other conservation practices, including crop rotation, contour farming, and agricultural terracing. Finally, we discuss the critical effect of soil conservation and conservation agriculture on land prices and how these factors may affect farmers' decision-making.
