Morfologia e estabilidade de agregados de um Latossolo em função do manejo e da

After being air dried and clod crushed by hand, the fraction that passed through a sieve with 9. The stability estabilidade de agregados aggregates was obtained by sieving in water, using a vertical oscillator of amplitude of 0.

With these values, it was calculated estabilidade de agregados mean weight diameter MWD by the equation 1, and the geometric mean diameter GMDby the equation 2.

To determine the morphological characteristics, aggregates were collected in the screens of 4. At the time of sample collection, the aggregates were separated by sieving with ten light and constant movements, then they were packed in a smooth and rigid plastic container, protected by two foam layers top and estabilidade de agregados and transported without agitation that could change the original structure.

The samples were air dried before being subjected to analysis.

Approximately 60 aggregates estabilidade de agregados randomly distributed on a scanner HP C, with optical resolution of dpi for imaging. The images were processed using the software Quantporo.

The access to both serial titles and articles is available via indexes and search forms. Lookup the document at: The destruction of soil aggregates can be considered as the beginning of the erosion process and this has been estabilidade de agregados as an index of erodibility Castilho et al.

The management, use and duration of soil use promote different estabilidade de agregados in soil properties, such as structure, which is related to the aggregation.

Water stable aggregates contribute to improving the porosity and thereby greater infiltration and erosion resistance Matos et al.

Besides aggregation induced by roots, the stability of aggregates is also determined by cementing agents such as organic matter and iron oxides estabilidade de agregados and goethitealuminum gibbsite and calcium.

Gypsum is one of the main sources of calcium of a relatively low cost.

Its effects on the flocculation of soil particles reflect in the improvements of soil structure estabilidade de agregados aggregation Rosa Junior et al. Cremon discuss that the use of digital analyses to measure the quality of the soil allows the characterization of the aggregates according to their geometric shapes, using measures and indices of micromorphometry.

Understanding and quantifying the impact of the use and management of soil in its estabilidade de agregados quality are fundamental in the development of sustainable agricultural systems.

The objective of the site is to implement an electronic virtual library, providing full access to a collection of serial titles, a collection of issues from individual serial titles, as well as to the full text of articles. To determine the morphological characteristics, aggregates were collected in the screens of 4.

At estabilidade de agregados time of sample collection, the aggregates were separated by sieving with ten light and constant movements, then they were packed in a smooth and rigid plastic container, protected by two foam layers top and bottom and transported without agitation that could change the original structure.

The samples were air dried before being subjected to analysis. Approximately 60 aggregates were randomly distributed on estabilidade de agregados scanner HP C, with optical resolution of dpi for imaging.

The resolution used in the image acquisition was dpi, for both classes of aggregates analyzed. This resolution has the capacity to estabilidade de agregados and analyze different images and measure or evaluate the morphological characteristics of objects in general. The RGB colour system was used in the preparation of images for further analysis, with the colors formed by the combination of wavelengths of red, green and blue.
