1. Introduction to Fiji soilsFiji Soil Map is based on:Soil Taxonomic Unit Description Handbook (STUD’s 1998) LESLIE, D.M. (David Murdoch), 1940- Fiji : soil taxonomic unit description handbook / D.M. Leslie, V.B. Seru. - Lincoln, Canterbury: Manaaki Whenua Press. 1998.

Volume 1 & 2: ~ 950 pages

1. Introduction to Fiji soils- Classifies 227 soils of Fiji- Each Soil has an Individual Soil Map Unit Codemain characteristics: Range of Slopes, Moisture Regime, Temperature Regime (Altitude > 600m),

Texture, Mineralogy Class, Landform, parent Rock, Drainage, Erosion Risk……. etc.
