ABSTRACT: The Cerrado is the largest savanna biome in the Neotropics and considered a major hotspot for world biodiversity. However, over recent decades the area has increasingly been converted to intensive agricultural ecosystems, primarily for soybean production. Conservation tillage systems have gained major importance in tropical America, especially in the Brazilian Cerrado. Long-term field experiments were established to evaluate the effects of soil tillage on soybean production in the Cerrado. The aim of our study was to determine arbuscular mycorrhizal fungi (AMF) diversity in three natural savanna forests and compare with AMF communities established in three field experiments focusing on soybean production. Since 2000, these experiments differed only in the crop rotation. In one experiment, the rotation was bi-annual with soybean and maize, in the second soybean was mono-cropped, and in the third the soybean/maize rotation was on a more intensive, annual basis. AMF spores were extracted from the soils, counted and morphologically identified. In total, 63 AMF species, belonging to 20 genera, were detected. Average spore densities and species richness decreased in conventionally tilled systems (3-4 spores g(-1) and 12-17 species), when compared to no-tillage (4-6 spores g(-1) and 15-18 species) and natural savanna (9-11 spores g(-1) and 16-22 species), but AMF evenness (Pielou index) was higher under both tillage systems (0.65-0.77), than in the savanna forests (0.54-0.62). AMF community composition significantly differed between all systems. Indicator species were revealed for all three ecosystems: e.g. Glomus macrocarpum and Sclerocystis sinuosa (Cerrado), Sc. coremioides (no-tillage) and Gigaspora margarita, Racocetra coralloidea and Ra. fulgida (tillage). In conclusion, soil cultivation and fertilizer application lead to decreased AMF species richness but remarkably AMF diversity was maintained on similarly high levels in soybean-based crop production systems, even under intensive soybean mono-cropping. The changes in AMF community structure rather were linked to soil pH and potassium, calcium and magnesium than to phosphorus availability or the organic carbon contents. Several species were unrecoverable from either of the tillage systems following conversion from natural savanna forests to cropland.

The common bean production system is majorly based on the use of granular fertilizers to provide nutrients for the crop. Studies on the use of liquid fertilization at an appropriated depth and, seed inoculation with Rhizobium tropici can provide significant increases in the grain yield of the common bean. The objective of this study was to determine the growth and productivity of common bean as affected by N-P formulations, application depths and the inoculation with R. tropici. Field experiments were carried out in 2015 and 2016 cropping years using a complete block design, in a 2x2x2 factorial arrangement, with four replicates. The treatments involved the combination of N-P formulation (granular and liquid), two application depths of the N-P formulation (6 and 12 cm) and with or without rhizobia inoculant. The plant density (PD), number of pods (NP), number of grains (NG), mass of 100 grains (M100) and grain yield (GY) were determined. The granular and liquid N-P formulations provided similar results for PD, NP, NG, and GY of common bean. Similarly, the application depth of the N-P formulations did not affect GY. Inoculation of the seed with R. tropici stimulated NP and NG, increasing GY. Growth and productivity parameters were equally affected by the type of formulation and application depth; however, GY was greater with rhizobial inoculant. Thus, the liquid N-P formulation, applied at 6 cm depth, associated with rhizobial inoculant can improve the crop management providing better control of application uniformity, minimal soil mobilization, less fuel consumption, and increased grain yield.
