In greenhouse,13 treatments were conducted.The study on nutrient defi-ciency
treatments of Eucalyptus grandis seedlings showed that more than one nutrient limitedgrowth
of heights, diameter and biomass production of E. grandis seedlings in each of thetropical soils
that were examined, and biomass is most sensitive in the three indexes. Nutri-ents that limited
seedling growth on each soiI type were:P and Ca of Galmara soil;P,N andS of Tyson soil;P and
Ca of Pigin soil; P,N,S,Zn and B of Kirrima soil;P,N,K and S ofBulgun soil;P,N,K,S,Zn and Mo of
Hull soil.When these nutrients that mentioned abovewere omission from the complete nutrient
formulation(COM)in the relative soil types,biomass above ground(Da)of seedlings were
reduced by 24%~98%,comparing with Davalues of COM treatment.A simple guide to diagnosis
of foliar symptoms of deficiencies of 5major elements(N,P,K,S and Ca)has been prepared.
