Study on Nutrient Content and Accumulation of Leucaena Leucocephala Stands with Different Densities

Abstract

Nutrient content and accumulation were studied in young Leucaena leucocephala stands with different densities (1, 2, 4 and 8 seedlings mâ€2) to provide theory basis for their reasonable management. The results showed that N and K contents were high and P content was low in various organs, and total nutrient content decreased in the order of leaves>bark>branches>roots>stem. Nutrient accumulation of single tree decreased with increasing stand density, whereas the nutrient accumulation of stands increased with increasing plantation density. The N or K accumulation was greater than P accumulation for each density stand.
