Description In order to study the “Biomass Production and Nutrient Contents
in 8-year old Poplar Plantation” 8 years old popular plantations grown
under 5x4 m, 10x2.5 m and 15x2.5 m spacing were selected. Seven
trees in each spacing were felled for recording observations for biomass
production and nutrient analysis.
The total amount of biomass production was maximum in 5x4 m
spacing, followed by 10x2.5 spacing and minimum in 15x2.5 m
spacing. About 75 percent of biomass was contributed by stem only.
The concentration of N, P and K was maximum in leaves at
15x2.5 m spacing and decreased with decrease in spacing. Secondary
nutrients (Ca, Mg, S) also followed the similar trend. Their
concentration was also maximum in leaves. Concentration of Zn, Fe,
Cu and Mn was recorded maximum in 1.5x2.5 m spacing and
decreased with increase in spacing. Zn and Cu concentration were
maximum in leaves, while the concentration of Fe & Mn were higher in
roots.
The uptake of all nutrients analysed was maximum at 5 x4 m
spacing and their major portion was accumulated in the stem in all the
spacings.
In soil concentration of available N, P, K, Ca, Mg, S &
micronutrients were maximum at surface layer in all the spacing,
which decreased with increase in sampling depth.
