The volumetric ring and the computerized tomography (CT) techniques were applied to study soil bulk density, in order to understand the compaction of an Albaqualf soil (Planosol) of the Rio Grande do Sul State, Southern Brazil (latitude 31 52' 00'' S and Longitude 52 21'24'' W). Among six different tillage systems and crop rotations the greatest soil bulk density was measured for the continuous irrigated rice crop system and the lowest for the no-tillage treatment under rye grass straw. |

Conteúdo: |
Different feedstocks and different pyrolysis processes produce carbonized materials (biochar) with different properties. The properties of these materials are very important when considering their agricultural uses. The technique of 13C Nuclear Magnetic Resonance (13C-NMR) is a very powerful tool for the characterization of the complex products, especially when aided by multivariate statistics, such as Principal Component Analysis (PCA). In this work, a series of feedstocks, embracing agro-industrial residues (sugarcane straw, orange bagasse, grass straw, soybeans, castor oil and Jatropha cake), urban residues (sewage sludges) and industrial residues (blended refuse) were submitted to two different fast pyrolysis processes, said processes 1 and 2. |
