摘要

"Leek" (Allium porrum, L.) was cultivated in randomised pots with the application of several inorganic and organic fertilisers. Soil and leaching chemical properties were evaluated. Plants were fertilised with three nitrogen levels (0; 0.8; and 1.6g/pot). The inorganic fertilisation treatments included a conventional inorganic fertiliser, CIF (Foskazoto 15:15:15) and a controlled release fertiliser, CRF (Osmocote 5-6M, 15:10:12, 2Mg). The organic fertilisation treatments consisted of sewage sludge(SS), mild sludge (MS), and two commercial organic fertilisers, Sansao (SA) and Setsolos (SET). The soil was a Calcic Luvisol (LVk), according to the FAO-UNESCO Soil Classification; its pH was 7.7, organic matter content was 2.1 percent and initial N, P_2O_5, K_2O soil contents were, respectively, 1673; 46; and 482 mg kg~(-1). Several parameters were determined in the soil: pH, electrical conductivity (EC), organic matter content (OM), nitrogen (N), assimilable phosphorous (P), assimilable potassium (K), iron (Fe), copper (Cu), manganese (Mn) and zinc (Zn). Cadmium (Cd), chromium (Cr), nickel (Ni) and lead (Pb) were also performed. Some Pb soil contamination was detected with the SET treatments. Parameters such as pH, EC, nitrate (NO_3~-), K, Cu, Zn,Cd, Cr, Ni and Pb were determined in pot leaching samples. These analyses showed no Cd, Cr, Ni, and Pb contamination. Concerning the nitrate contamination, significant differences were obtained between the organic and the inorganic treatments. At the endof the experiment, the highest nitrate leaching content was determined in the CRF treatment. The data were statistically analysed by ANOVA and comparative analyses of the means were performed by Duncan test using the SPSS Programme.
