Atributos Microbiológicos, Químicos E Físicos De Solo Sob Diferentes Sistemas De Manejo E Condições De Cerrado

Abstract: INTRODUÇÃOO manejo agrícola é sustentável somente quando a qualidade dos recursos solo, ar e água é mantida ou melhorada, e, no caso do solo, a qualidade depende da manutenção e melhoria de seus atributos físicos, químicos e biológicos, bem como de sua contínua capacidade de produzir alimentos e fibras (Doran & Parkin 1994).Os solos sob Cerrado, no Brasil, em geral, apresentam condições físicas favoráveis à agricul- ABSTRACT RESUMOtura e vêm sendo, gradativamente, explorados com culturas anuais, pastagens e, m… Show more

“…The soil is one of the most heavily exploited natural resources (Fernandez, 2006), and the implementation of agricultural systems with inadequately understood effects on the soil can lead to environmental degradation (Roth & Pavan, 1991;Silva Neto, Silva, Inda, Nascimento, & Bortolon, 2010;Lourente et al, 2011;Sabiha, Salim, Rahman, & Rola-Rubzen, 2016;Silva et al, 2017). The demand for appropriate techniques to measure the impact of human actions on soil quality is even more significant when the aim is to obtain a production system that is adapted to the characteristics of each soil class (Barreto, Miranda, Diniz Filho, Lira, & Medeiros, 2014;Shao et al, 2014;Kong, Miao, Wu, & Duan, 2016;Zhang et al, 2016).…”

“…In the search for appropriate ways to evaluate the impacts of human practices on soil quality, several researchers have recommended that the evaluation of soil physical indicators should have simple and lowcost methodologies, enabling faster analysis (Mendes, Melloni, & Melloni, 2006;Nesbitt and Adl, 2014;Sun et al, 2014;Faleschini, Zanini, Pellegrino, & Pasinato, 2016), and better reflecting the differences in soil quality (Araújo, Goedert, & Lacerda, 2007;Garcia & Rosolem 2010;Barreto et al, 2014;Desjeux et al, 2015;Duval, Galantini, Martinez, López, & Wall, 2016;Sarathjith, Sankar, Wani, & Sahrawat, 2016). Since aggregates constitute the main structural components of the soil, they have been widely used as quality indicators in conservation systems (Dexter, 1988;Ferreira, 2010;Lourente et al, 2011;Juhos, Szabó, & Ladányi, 2016;Rojas, Prause, Sanzano, Arce, & Sánchez, 2016).…”

“…Este método tradicional tem como característica a prática itinerante de derruba e queima da vegetação para o preparo da área e posteriormente plantio (Ferreira et al, 2014;Silva et al, 2015). Durante o tempo de recuperação da fertilidade do solo (pousio) ocorre concomitantemente o restabelecimento da vegetação e a promoção dos ciclos biogeoquímicos do ecossistema (Lourente et al, 2011).…”

“…Maintaining crop residues on the soil surface is a common practice in a low-management cropping system, and is an alternative for enhancing soil quality through an increase in aggregate stability, porosity, water holding capacity, and reduced water loss through evaporation (Lourente et al, 2011). Despite the adoption of low-management practices in most soybean-growing areas, agricultural expansion for grain cultivation involves the removal of native vegetation and the use of agricultural inputs (Bresolin et al, 2010).…”

“…Agriculture expansion into the Cerrado (Brazilian tropical savanna) environment has led to rapid conversion of this biome into large areas of cattle farming, reforestation, and grain growing, especially soybeans (Bresolin et al, 2010;Lourente et al, 2011). The natural conditions of the Cerrado, such as flat terrains, enable agricultural mechanization and technological development for selection of cultivars highly efficient in nitrogen fixation.…”
