The use of pyrolysis products of manures gives positive effects on soil fertility, crop productivity and soil carbon sequestration. However, effects depend on soil characteristics, plant species and the raw material from which the biochar is derived, and some negative effects of biochar have been reported. The objective of this study was to evaluate the effectiveness of poultry manure ( PM )‐derived biochar on the growth, and P , N , K , C a, M g, F e, Z n, C u and M n concentration of lettuce ( L actuca sativa L.) plant. The treatments as follows: control, 20 g/kg poultry manure ( PM ), 20 g/kg phosphorus‐enriched poultry manure ( PM + P ), 10 g/kg B iochar ( B ), 10 g/kg B iochar+ P ( B + P ). Application of biochar and PM significantly increased lettuce growth, and P ‐enriched forms of PM and biochar gave the higher growth. PM has no significant effect on the N concentrations but biochar and, P ‐enriched PM and biochar treatments significantly increased N concentrations. Phosphorus concentration of the lettuce leaves significantly increased by PM and biochar treatments. Plant K concentrations were also increased by PM and biochar, and their P ‐enriched forms. Leaf C a and M g concentrations were lower in B iochar and B + P treatments than that of PM and PM + P treatments. Compared to control and PM treatments, biochar applications reduced F e, Z n, M n and C u concentrations of the lettuce plants. The results of this study indicated that application of biochar to alkaline soil is beneficial for crop growth and N , P and K nutrition, but it certainly reduced F e, C u, Z n and M n nutrition of lettuce.
