Litter Production and Nutrient Concentration under High Density Plantation in Some Fuelwood Species Grown on Sodic Soils

An estimate of macro-nutrients and litter production was evaluated in 5 year old plantations of Acacia farnesiana, Acacia nilotica sub sp. cupressiformis and Cassia siamea planted at three spacings corresponded to densities of 10, 20 and 30 thousand trees ha ^-1 on sodic soils at Biomass Research Centre. Banthra of National Botanical Research Institute, Lucknow, India. The litter yield increased with increasing plantation densities. The concentration of macro-nutrients in the leaf litter did not change due to planting spaces although differences between species existed.
