The change in soil properties under fresh and replanted poplar sites was carried out at the University Seed Farm, Ladhowal, Punjab Agricultural University, Ludhiana. Analysis of soil showed that K, P and pH was low in replanted site than the fresh site, whereas, EC, OC, N and total soil organic carbon was higher on replanted site as compare to the fresh site. Highest per cent OC and N were found in poplar + turmeric combination with added pruning material. With depth, soil pH, bulk density increased while other parameters such as EC, P, K, OC and N decreased with depth from surface layer (0–15) to sub-surface layer (15–30). Total carbon storage in soil was recorded more in the agroforestry combinations (poplar + turmeric) than in poplar plantations without inter-cultivation.
