- Abstract
A study was carried out to examine the regular changes in the nutrient status under different land utilizes of tropical deciduous forest of Central Uttar Pradesh. Dry tropical soils were examined to analyses the seasonal dynamics of microbial biomass carbon, phosphorus and nitrogen. Other soil properties like pH, total organic carbon, total nitrogen, available phosphorus exhibit strong seasonality and comparatively they are higher in forest soils as compared to agricultural soils. At all the sites, the maximum MBC, MBN and MBP occurred during the dry period (summer season) and the minimum in wet period (rainy season). Increased demand for plant nutrients during the rainy season reduced the supply of nutrients to soil microbes and thus low microbial biomass C, N and P. In the present study soil MB-C, MB-N and MB-P were higher at forest sites as compared to agricultural sites. Such findings suggest that the preservation of nutrients by soil microbial biomass was better in the limited logging stand which will lead to the recovery of forest under conservation. The differences in MBC, MBN and MBP were significant (P <0.001) among sites and seasons. The MBC (P < 0.0001), MB-N (P < 0.001) and MB-P (P < 0.0001) were positively correlated with organic C. Therefore, the minimum and maximum microbial biomass C, N and P during the rainy and winter season indicate a balance between a nutrient demand for plant growth and nutrient retention in microbial biomass that will help to recover the environment after disruption.
