Mg, and K) in various plant parts of three different dominant trees i.e., Acacia
senegal (As), Acacia tortilis (At) and Eucalyptus camaldulensis
(Ec) was estimated. Concentration of nutrients was estimated for bole, first
order branch, other branch, foliage, seeds, stump root, lateral root and fine
roots. The study was carried out in the sand dunes of Western foot hill gaps
of Central Aravalli located at a distance of 10 km n-w to Ajmer, a centrally
situated city of Rajasthan. The concentration of nutrients was found to be maximum
in foliage except for nitrogen which was estimated higher in seeds of A.
senegal and A. tortilis. A different pattern was recorded for E.
camaldulensis where N, Ca, and Mg were recorded maximum in other branch,
while p and K in foliage parts. Result shows the concentration of nutrients
in different tree components in the order: foliage>seeds> their branch>first
order branch>bole, and in root components: fine root>lateral root>stump
root. Total nutrient concentration was found to be maximum in As followed by
At and Ec. It is concluded that the foliage component of various trees has maximum
nutrient concentrations. There are marked variations in the concentration of
different nutrients in each component.]]>Attiwill, P.M.,1979Eucalyptus oblique (L' Herit) forest. III.
