Loss of plant diversity and poor regeneration potential are important ecological problems in the tropical deciduous forests (TDFs)
across the globe. Many researchers have studied the structural complexities, regeneration pattern of native plant species, changes in
diversity indices, fragmentation, patch formation etc., to understand the ecological consequences of forest degradation. In Southeast
Asia, many researchers have studied the loss of mixed nature of plant communities in Sal forests due to the alterations in the nutrient
dynamics, litter decomposition, loss of moistures, changes in phenology of native plant species, changes in microbial activities, etc.
The importance of macronutrients and micronutrients in plant growth and soil fertility are well known, however, these are poorly
described soil components of TDFs in the world. In present study, the spatial and seasonal variations in biogeochemical parameters
were studied in twenty forest soils collected from four Sal forest sites of Chhotanagpur Plateau in India. The pH of soil samples varied
from 5.8 to 6.4 in winter, 4.3 to 5.4 in summer and 6.5 to 6.8 in the monsoon. Seasonal variations in C:N ratio showed lowering of
C:N ratios in the monsoon. The elemental concentrations were found below the average earth crust values indicating shallow nature
of forest soils. The species poor sites were deficient in Ca, Fe, Mg, Mn and P. These elements showed greater concentrations and less
degree of spatial and temporal variations at species rich sites. In the Chhotanagpur TDF soils, least abundant element was phosphorus
indicating the predominance of strongly weathered soils and contain low concentrations of extractable P.
