R. da the present study, we evaluated the influence of agroforestry systems and traditional agriculture on the physical attributes and biologicals of soil, using as reference a native forest area in Paraty,... ... |
 Author(s): SCORIZA, R. N.; CORREIA, M. E. F. A disused electrical substation was the site of the spill of 40,000 L of Ascarel oil. However, none of the expected principal contaminants were chemically detected above established guidelines. Since... ... |
 Author(s): MACEDO, M. C. M.; ARAUJO, A. R. de; ALMEIDA, R. G. de; FERREIRA, A. D.; TOMAZI, M. Pasture and soil degradation in Brazil are the main constraints in conventional systems to animal and grain production. Soil quality in terms of carbon content in these soils is a useful tool to estim... ... |
 Author(s): GOMES, J. B. V.; FERNANDES, M. F.; BARRETO, A. C.; ARAUJO FILHO, J. C. de; CURI, N. This study evaluated the changes occurred in a set of soil attributes, particularly those related to the dynamics of soil organic carbon (SOC), as a function of the replacement of native forest for ag... ... |

 Author(s): NASCIMENTO, B. M.; CESÁRIO, F. V.; BALIEIRO, F. de C.; RODRIGUES, R. de A. R.; WANDERLEY, H. S. The deposition of atmospheric nitrogen has been increased in urban forest ecosystems, yet it is not clear how this increase affects soil respiration in the short term. The soil respiration could contr... ... |

ABSTRACT: The Random Forest algorithm is a data mining technique used for classifying attributes in order of importance to explain the variation in an attribute-target, as soil CO2 flux. This study ai... ... |
