ABSTRACT The implementation of conservationist systems that improve soil properties and reduce the impacts of the conversion of native areas is fundamental for feasible agricultural exploitation. This study aimed to evaluate the impact on soil biological properties caused by the conversion of murundus fields into agricultural systems and verify the ability of the no-tillage conservation system to recover these properties over the years. Treatments consisted of three agricultural areas subjected to the same management (no-tillage), in a chronosequence (7, 11, […]

Arbuscular mycorrhizal fungi in “murundu fields” after conversion to farm systems in the cerrado

Paula Camylla Ramos Assis, Orivaldo José Saggin Júnior, Helder Barbosa Paulino, Sidney Luiz Stürmer, José Oswaldo Siqueira, Marco Aurélio Carbone Carneiro


The murundu fields (Campos de Murundus) are characterized by mounds occurring in some parts of the Cerrado (Brazilian tropical savanna) biome with important ecological functions for the maintenance of soil sustainability. Conversion to agricultural systems may lead to changes in physical, chemical, and biological soil properties not yet assessed, such as reduction in the biodiversity of arbuscular mycorrhizal fungi. The aim of this study was to evaluate how the conversion of mound fields into agricultural areas changes the community of […]

Gypsum in management systems and soybean productivity in southwest region of Goiás

Lucimeire Neis, Helder Barbosa Paulino, Edicarlos Damacena de Souza, Edésio Fialho dos Reis, Flávio Araújo Pinto


The tilling of areas in no-tillage to several years and the use of gypsum practices are observed among the farmers in southwestern Goiás. This study was carried out to evaluate the effect of gypsum rates (0, 1, 2, 4 e 6 Mg ha-1) on some chemical attributes in the soil’s depth and in soybean yield in area under long-term no-till, with and without tillage. A complete randomized block scheme with a split-split-plot design with four replicates was used. The area […]
