Micotoxinas associadas aos grãos são uma das principais causas de não conformidade em relação a alimentos seguros e as impurezas e/ou matérias estranhas presentes podem estar associadas à sua maior incidência. Amostras de grãos de soja e respectivas impurezas foram avaliadas na recepção e na expedição de uma Unidade Armazenadora de grãos da região norte do Estado do Paraná na safra 2008/2009. As micotoxinas avaliadas no Laboratório de Análises Micotoxicológicas (LAMIC, em Santa Maria-RS) foram: aflatoxinas (B1, B2, G1, G2), deoxinivalenol, nivalenol, ocratoxina A e zearalenona. Os resultados mostraram baixa ocorrência de micotoxinas em grãos de soja quando armazenados de forma correta. A grande fonte de contaminação por aflatoxina e zearalenona são as impurezas e/ou matérias estranhas permitidas na legislação brasileira até o limite de 1%. A legislação deve ser alterada e deve ser adotado o limite zero de impurezas, na etapa de expedição, visando garantir a segurança alimentar na cadeia produtiva da soja. Mycotoxins are an important contaminant on grains mainly on the impurities which coming with from the field during harvesting. Samples of soybean grain and their impurities were taken at reception of storage unit, during storage period and at delivering to industries for processing at a Grain Stored Unit located at north of Parana State 2008/2009 crop season. The mycotoxins evaluated at Analytical Laboratory Mycotoxicological (LAMIC in Santa Maria / RS) were: aflatoxins (B1, B2, G1, G2), deoxynivalenol, nivalenol, ochratoxin A and zearalenone. Results showed that soybean grains when stored properly have low occurrence of mycotoxins. The major source of contamination by aflatoxin and zearalenone were impurities allowed at a rate of 1% by Brazilian legislation. The legislation should be amended and adopted the zero limit of impurities in the stage of shipment in order to ensure a safe food in soybean chain.

Pasturelands, often degraded, represent most of the converted lands globally. It is important to understand how different pasture management approaches can improve soil quality, increase feed production and farmer income. Here, the impact of different soil enhancers on soil quality and productivity of three cultivars of Brachiaria (Syn. Urochloa) forage grass is presented. Soil enhancers included: biochar - a carbon-rich product from biomass pyrolysis, moinha (local charcoal residue), traditional fertiliser containing nitrogen, phosphorus and potassium, lime, and forage peanut (Arachis pintoi cv. Amarillo). Considering the total biomass produced over the experiment (sum of four harvests), the highest dry biomass production was observed for Brachiaria brizantha cv. Piatã (14.1 Mg ha-1) and cv. Marandu (12.7 Mg ha-1), for biochar application of 30 Mg ha-1. Paiaguás had the highest dry matter production (12.4 Mg ha-1) for the treatment with forage peanut plus 15 Mg ha-1 of biochar. The increases in dry mass production translated to additional income, as compared with the control, of U$ 1 291, U$ 1 183 and U$ 991 per year for Marandu, Piatã and Paiaguás, respectively. The increases in forage grass productivity were reflected by positive changes in soil characteristics such as improvement in cation exchange capacity, pH and nutrient contents. Improved management of tropical pasturelands holds opportunity for more sustainable food production, and for ecosystem services protection and recuperation, for example, biodiversity net-gain, water regulation and carbon sequestration.
