Loading Duration Effect on the Compressibility Characteristics of Treated Semi-Arid Soil

Aspergillus fuscicans, a new species within Aspergillus section Usti from Argentinean semi-arid soil is introduced. Molecular, morphological and physiological studies were conducted, based on sequence analysis of partial β-tubulin and calmodulin sequence data. Aspergillus fuscicans formed a distinct, well-defined clade related to A. calidoustus and A. pseudodeflectus. In addition, A. fuscicans was able to grow and sporulate at 37 ºC, and had a negative Ehrlich reaction. Morphological and physiological features could be used to differentiate the new species from its phylogenetically related taxa.

Movement of salt in a semi-arid soil (Hanwood sandy loam) was studied in isolated columns of soil one metre in diameter and four metres deep. Where a water-table was maintained approximately 60 cm. from the surface by the addition of rain-water to the surface, salt was washed out of the surface layers and did not return. Where a water-table was maintained one metre from the surface by the addition of water from below there was a small increase in the salt concentration of the surface 10 cm. of soil. In view of these results it is suggested that some circulation of water involving lateral movement is generally associated with salt accumulation that is commonly found under field conditions.
