Conteúdo:  Fermented composts obtained from a mixture of raw materials and a microbial inoculant, known as ?bokashi,? are alternatives used by many farmers worldwide. We evaluated the chemical composition, fermentation pathways, N availability, and agronomic efficiency of fermented compost obtained from different plant-based raw materials. The standard compost formulation composition was 60% wheat bran and 40% castor bean bran; this formulation gradually replaced wheat bran by the coffee husk, brewery residue, and elephant grass bran, and leguminous bran replaced castor bean bran. Incubation tests evaluated nutrient content (C, N, P, K, Ca, Mg), pH, electrical conductivity, and fermentation pathways (by the organic acids lactic, acetic, propanoic, butyric, and ethanol). A bioassay in greenhouse conditions accessed N availability. Additionally, a field experiment evaluated the agronomic efficiency of 5 formulations and 4 doses (0 to 400 kg N ha?1) in successive vegetable production. The formulations with a balanced C/N ratio could combine desirable fermentative and nutritional characteristics with good N availability and plant growth. Some formulations drastically changed the compost characteristics, especially the complete replacement of wheat bran for coffee husk and elephant grass, which presented undesirable fermentation pathways. Leguminous bran maintained the fermentative quality and increased the soil?s biological activity but decreased the nutrient content, N availability, and v... Mostrar Tudo

Título:  Physical-chemical and microbiological changes in Cerrado Soil under differing sugarcane harvest management systems.
Ano de publicação:  2012

Conteúdo:  Abstract Background: Sugarcane cultivation plays an important role in Brazilian economy, and it is expanding fast, mainly due to the increasing demand for ethanol production. In order to understand the impact of sugarcane cultivation and management, we studied sugarcane under different management regimes (pre-harvest burn and mechanical, unburnt harvest, or green cane), next to a control treatment with native vegetation. The soil bacterial community structure (including an evaluation of the diversity of the ammonia oxidizing (amoA) and denitrifying (nirK) genes), greenhouse gas flow and several soil physicochemical properties were evaluated. Results: Our results indicate that sugarcane cultivation in this region resulted in changes in several soil properties. Moreover, such changes are reflected in the soil microbiota. No significant influence of soil management on greenhouse gas fluxes was found. However, we did find a relationship between the biological changes and the dynamics of soil nutrients. In particular, the burnt cane and green cane treatments had distinct modifications. There were significant differences in the structure of the total bacterial, the ammonia oxidizing and the denitrifying bacterial communities, being that these groups responded differently to the changes in the soil. A combination of physical and chemical factors was correlated to the changes in the structures of the total bacterial communities of the soil. The changes in the structures of the funct... Mostrar Tudo
