Abstract: The aim of the present work was lo investigate the status of the sol biological parameters of the lea soils under organic and inorganic (convenlional; input management practices. The soils Here collected from selected conventional and orga111cally managed tea gardens during the month of June. 2008. The results show that the soil biological parameters (e.g., microbial biomass carbon (MBC.), soil respiration (basal !BSR) and substrate induced (SIR)), fluorescein diacelale hydrolyzing activity (FDHA) and {3-glucosidase aclivily, numeric acid and ergosterol conlenls were higher in orgamcally than the conventionally managed lea gardens. Data revealed that the organic co111pared lo conventional management practices improved soil biological parameters which in turn may help to improve the soilhealth.
