Biogenic and physicogenic aggregates: formation pathways, assessment techniques...
Pereira, Marcos Gervasio; Loss, Arcangelo; Batista, Itaynara; Melo, Thadeu Rodrigues de; Neto, Eduardo Carvalho da SilvaThe soil particles can be gathered through physical and/or chemical processes in association with the biological activity, leading to the formation of aggregates. Soil aggregates has several functions in the soil, increasing macroporosity and water circulation - consequently reducing soil erosion and mechanical resistance to root growth, contributing to greater fixation of plants to the soil and absorption of w...
Physicogenic and biogenic aggregates under different management systems in the ...
Pinto, Luiz Alberto da Silva Rodrigues; Torres, José Luiz Rodrigues; Morais, Igor de Sousa; Ferreira, Robert; Júnior, Wanderson Farias da SilvaAn important strategy for the sustainable management of Cerrado soils is no-till (NT) systems, which may improve soil properties, particularly aggregation. Soil aggregates can be categorized according to their formation pathways into physicogenic (Phy) and biogenic (Bio). This study aimed (i) to quantify the relative proportion of physicogenic and biogenic aggregates and (ii) evaluate the levels of total organi...

Fernandes Filho, Elpídio Inácio; Campbell, Patrícia Morais da Matta; Francelino, Márcio Rocha; Demattê, José Alexandre Melo; Pereira, Marcos GervasioQuantification of soil properties is essential for better understanding of the environment and better soil management. The conventional techniques of laboratory analysis are sometimes costly and detrimental to the environment. Thus, development of new techniques for soil analysis that do not generate residues, such as spectroscopy, is increasingly necessary as a viable way to estimate a wide range of soil prope...
