Abstract: The present study was carried out to make a study on pH and Organic carbon of soil sample of three urban ponds of Nabadwip at Nadia district, West-Bengal. The monthly mean variation in soil pH ranged between 7.35 (January) and 8.61(May) in P-1, 6.21(January) and 6.90 (June) in P-2 and 6.20 (Feb) and 6.82(June) in P-3. The maximum mean value was recorded in P-1 and minimum in P-3. The soil pH was significantly highest (p<0.05) in the month of May than other month in P-1 but in case of P-2 and P-3 it showed significantly maximum value (p<0.05) in the month of June. In the present study the percentage of organic carbon varied from 2.43 (January) and 2.50% (April, May, June) in P-1, 2.53 (January) to 2.79% (May) in P-2 and 0.029 (January) to 2.26% (June) in P-3. The maximum average value (2.61%) was found in P-2 and minimum in P-3 (1.37%). The soil organic carbon was significantly highest (p<0.05) in June than other months in both P-1 and P-3. There was significant variation was found in between the months of May and June in P-1. In P-2 the maximum significant variation (p<0.05) was found in the month of May, but there was no significant variation (p>0.05) between the month of May and June. The present finding established that, the well managed pond (P-2) showed better ecological conditions compare to unmanaged ponds.
