Abstract

The present study was done in October 2008 and March 2009 to explore the seasonal effects on soil physico-chemical properties and fungal population found at different depth (that is, 5, 10 and 15 cm) as well as on plant parts. Results indicate that in both seasons, organic carbon, nitrogen, phosphorus and potassium was higher in the top 5 cm followed by lower depths (10 and 15 cm). Fungal species isolated from different soil depths indicate a decline in number of fungal species with an increase in soil depth, except in the rhizospheric region where the number of fungal species was higher due to highest microbial activity in this region and higher nutrient contents (due to degradation of organic compound into simpler one). In case of isolation from plant parts, it indicates that the population of fungal sp. was higher in root region compared to shoot region.

Key words: fungal species, physic-chemical properties, organic soil.
