FIERZ M.S.M. & ROSS J.L.S,

Quantifying Hardness Of Morphosculptural Units To Assess Environmental Fragility/Sensitivity: A Case Study From Sao Paulo-State Coastal Area.

Pages 17-26

Abstract

In principle, the coastal plains present the least resistance of materials as well as greater environmental fragilities. The objective of this study is to identify these differences along this plain in São Paulo state, with the use of accessible methodologies and material physical / chemical analysis. The highest points of material resistance are the highest points (SPODOSOL) of high soil organic matter (SOM – 90%), and iron (27%) contents as well as intense hardness, contrary to the hypothesis all coastal plain presents unconsolidated material and high fragility /sensitivity.
