“…It could be observed due to a negative sign of b and e parameters; as well as a positive of c and f, in each equation (Table 4). Tormena et al (1998), Blainski et al (2009) and Serafim et al (2013) had also reported the same correlations. The PR reduction with increased Θ is due to a lubricating effect of water, which reduces soil particle cohesion (TORMENA et al, 2007;PETEAN et al, 2010).…”

“…The CI of Bd (CI Bd ) enabled predicting alterations undergone by all soil properties under all land uses and management systems, anticipating potential negative consequences for soil physical quality. In this sense, Serafim et al (2013) suggested these indexes to be taken into consideration in farm planning, aiming to maintain physical quality of the soils.…”

“…In studies on suitable techniques for cropland use and management, several Brazilian authors have suggested as soil quality indicators a large number of physical and mechanical properties as aeration, water storage capacity and penetration resistance (PR) (OLIVEIRA et al, 2004;ARAÚJO et al, 2007;SEVERIANO et al, 2011;LIMA et al, 2012;SERAFIM et al, 2013;SILVA et al, 2015a). These properties are chosen for being sensitive to impacts against soil (MENDES et al, 2006;PRAGANA et al, 2012;SILVA et al, 2015a).…”

The Cerrado biome has outstanding territorial relevance in the state of Piauí, in which weather conditions, relief and favorable soil has made this region one reference in food production. This study focused to evaluate the effects of different land uses, management systems and their respective terms on organic carbon content and physical properties of a Latossolo Amarelo (Oxisol) in the Southwestern Piauí state. The study was performed in the city of Uruçuí, situated in the southwestern Piauí state. We assessed nine farming areas with different backgrounds regarding land-use, management system and run time. The treatments consisted of areas under no-till for 3 and 6 years (NT3 and NT6), under pasture for 2 and 5 years (PA2 and PA6), under eucalyptus plantation for six and twelve years (EU6 and EU12), under conventional tillage for two and 8 years (CT2 and CT8) and under native Cerrado (NC), which represented a reference condition. Conversion of the native Cerrado into no-till and grazing areas increased soil organic carbon content over time.

“…Based on the above, a soil management system with conservation practices combined with fertilization and concomitant agricultural gypsum application (CARDUCCI et al, 2014a(CARDUCCI et al, , 2014bSERAFIM et al, 2011SERAFIM et al, , 2013aSERAFIM et al, , 2013b can beneficially contribute in morphometric attributes of soil aggregates (size and structural arrangement). Thus, this research aimed at evaluating morphometric attributes of aggregates from a Inceptisol, after one year and a half of coffee farming (Coffea arabica L.) within the region of Alto São Francisco (MG), Brazil, under conservationist system of soil management.…”

Morphological characteristics of the soil aggregates are important tools to analyzing and monitoring the structural quality. The present study aimed to characterize morphometrically aggregates of a Inceptisol, originated from pelitic rocks, after 1.5 years of the implementation of a management system that adopts conservation tillage practices in the coffee cultivation. The aggregates were collected at the depths of 0.0-0.05; 0. 05-0.20; 0.20-0.40; 0.40-0.80 m, both at row and interrow position in a coffee field, and also a natural environment of native vegetation that was used as a reference for the study. The analyzes of the aggregates were carried through 2D images obtained by scanning at 300 dpi spatial resolution. Each image contained 60 households and were processed using the software QUANTPORO. The morphometric variables were obtained: area, perimeter, compactness, roughness, appearance and Ferret diameter. For validation, the correlations among morphometric variables determined by image analysis and pattern aggregation indices (GMD, MWD and aggregates retained in the class > 2.00 mm) obtained by wet sieving were studied. After 1.5 years of implantation increased the dimensions of the aggregates on the natural environment have been detected, as well as better structural quality Inceptisol. Key words: Image analysis.

O presente trabalho teve por objetivo caracterizar morfometricamente os agregados de um Cambissolo originado de rochas pelíticas (siltito) após 1,5 anos da implantação de um sistema de manejo que adota práticas conservacionistas do solo no cultivo do cafeeiro. Os agregados foram coletados nas profundidades de 0,0-0,05; 0,05-0,20; 0,20-0,40; 0,40-0,80 m, nas posições linha e entrelinha do cafeeiro e também em um ambiente natural Cerrado Nativo tomado como referência para o estudo. As análises dos agregados foram realizadas por meio de imagens 2D obtidas por escaneamento, em 300 dpi de resolução espacial. Cada imagem continha 60 agregados e foram processadas utilizando o software Quantporo. As variáveis morfométricas obtidas foram: área, perímetro, compacidade, rugosidade, aspecto e diâmetro de Ferret. Para validação, foram estudadas as correlações entre as variáveis 1 Parte da Dissertação do primeiro autor. Trabalho financiado pelos órgãos CNPq e FAPEMIG.
