The study investigated the effect of fertilization on soil properties under different poplar species in nursery condition in Kashmir. The experiment was laid out in split plot design (SPT) in nursery beds of (3.60m2) at spacing of (60cm x 30cm) with 36 treatments, four poplar species (Populus nigra, P. Ciliata, P. alba and P. balsamifera), three levels of N (N0, N75, N150 kg-1) and three levels of P (P0, P60, P120 kg-1) replicated three times. The results indicated that the chemical constituents of soil decreased in first year from initial values in respect of pH, N, P, K, Ca and Mg but increased subsequently in second year except pH. The average available soil N, P, K, Ca and Mg was recorded maximum at T9 (379.73, 383.51 kg ha-1), (20.53, 21.68 kg ha-1), (219.61, 220.90 kg ha-1), (845.88, 850.08 ppm) and 262.87, 263.56) ppm followed by T8 and T6 but lowest at T1 (373.00, 374.48 kg ha-1), (18.62, 19.09 kg ha-1), (217.09, 218.37 kg ha-1), (835.81, 840.45 ppm) and (258.32, 258.93 ppm), respectively. Among the species mean maximum decrease in first year from initial values and increase in second year in respect of N, P, K, Ca and Mg was recorded in P. balsamifera followed by P. nigra, P. ciliata and P. alba in both years, respectively. Hence, T9 (379.73, 383.51 kg ha-1) has been recommended as the best treatment for ETPs production of P. nigra, P. ciliata, P. alba and P. balsamifera through cuttings in nursery with regard to soil improvement in Kashmir.
