Five typical pedons representing major laterite landscape in tropical ecosystem of Goa viz., flat topped
hills, escarpments, conical hills, undulating hills and colluvial low lands under varying land use were
studied for their morphological characteristics, physical and chemical properties, soil genesis and
taxonomy. The soils were moderately to strongly acidic in reaction, very shallow to deep in depth
Texture of the soils varied from gravelly sandy clay loam to gravelly clay loam on hills, while it varies
from sandy loam to clay loam in undulating and colluvial low lands. The clay content, bulk density,
AWC, organic carbon, cation exchange capacity, base saturation and exchangeable hydrogen and
aluminium in the sols were ranged from 12.0 to 50.8 per cent, 1.37 to 1.53 Mg m-3
, 1.2 to 11.4 cm m-1
,
0.1 to 3.3 per cent, 3.9 to 12.4 cmol (p+) kg-1
, 21.9 to 66.5 per cent, 0.1 to 0.3 cmol (p+) kg-1
and 0.0 to
0.9 cmol (p+) kg-1
respectively. The soils had isohyperthermic temperature regime and ustic soil moisture
regime. The soils were grouped under three soil orders viz., Entisols, Inceptisols and Alfisols and further
classified into four families viz., Lithic Ustorthents, Lithic Haplustepts, Dystric Haplustepts and
Kanhaplic Haplustalfs.
