abstract
Soil sealing is a degradation problem that involves different factors, processes and mechanics. Different methods and methodologies to assess those factors and processes can reflect different results and levels of soil structure degradation within the same soil, under different climate and management conditions. Standardized methods were evaluated for assessing soil sealing in five Venezuelan soils, with different texture and organic carbon content. The objective is to select indicators for predicting soil sealing. The results showed that the amount of water stable aggregates (WSA), the medium weight diameter (MWD) of the aggregates, the particles with diameter < 0.25mm (P250), the absolute sealing index (ASI), the consistency index (C5-10) and the soil losses from simulation rainfall were able to evaluate the stability of the soil surface structure. However when all the methods were compared based on the classification criteria of each method, the MWD and C5-10 had a discrepant class of soil sealing degradation when compared with other methods. The WSA, P250, ASI methods and soil characteristics as SOM chemical fractions and particles between 2 and 100 μm diameters, had high correlations among each other but all had good relationship with soil losses under simulated rainfall. From this study it can be concluded that a simple laboratory method is enable to evaluate soil surface sealing susceptibility but the method needs to be validated under field conditions as well.
