Brazil is the largest exporter and the second-largest beef producer in the world. The country?s biggest challenge
has been to increase the production capacity of soils in an environmentally sustainable way. In this context,
agricultural practices that preserve the environment have demonstrated high productivity and sustainability by
emphasizing intensive grazing management and silvopastoral systems. In this study, the effects of the conversion
of a native forest (FO) into different pasture-based cattle production systems were assessed in long-term field
experiments using microbiological and physicochemical measurements. Five pasture systems were evaluated: i)
irrigated high stocking rate pasture (IHS); ii) rainfed high stocking rate pasture (RHS); iii) rainfed moderate
stocking rate pasture (RMS); iv) silvopastoral system with moderate stocking rate (SPS); and v) degraded pasture
(DP), the latter used as a reference for conventional pasture management, extensively used by farmers. Soil
samples (0?10 cm) were analyzed for bulk density (BD), total carbon content (TC), soil organic matter humification index (HLIFS), activities of soil enzymes β-glucosidase (BG) and arylsulfatase (ARYL), microbial biomass
carbon (MBC), and basal respiration (BR). The results showed that all managed pastures presented higher soil
carbon content than DP (16.2 ± 1.7 g kg− 1
), especially the RMS system, which presented the highest carbon
content (32.9 ± 0.9 g kg− 1
). Activities of BG and ARYL were more sensitive to detecting management changes
than MBC and BR. Increased activities of BG and ARYL were observed in the RMS system, possibly due to the
higher amount of biomass input, while this effect was less expressive in the other management systems. The
results indicated that soil enzymatic activities are sensitive to land use and management and could be used as soil
quality indicators in pasture-based beef cattle production for different systems in tropical soils. MenosBrazil is the largest exporter and the second-largest beef producer in the world. The country?s biggest challenge

Neste trabalho é descrito um método para inocular Corynespora cassiicola em plantas de algodoeiro. Testes foram realizados para avaliar os efeitos da temperatura na germinação dos conídios e no crescimento micelial do patógeno in vitro, além de testes in vivo em que foram avaliados temperatura, tempo de molhamento foliar e concentração de inóculo eficazes à infecção. O estádio de crescimento da planta de algodoeiro e a sua influência no sucesso da inoculação também foram avaliados neste estudo. O método proposto fornece resultados precisos e reprodutíveis para identificar a resistência/suscetibilidade de algodoeiros inoculados artificialmente com C. cassiicola em ambiente controlado. |
