Evaluation of productivity and rates of application of poultry manure for remediation of kerosene oil contaminated soil in Abakaliki, Southeastern Nigeria

This experiment was carried out in order to evaluate productivity and rates of poultry manure used to amend kerosene oil contaminated soil on 0.18 ha of land. The land area was contaminated with 5% of kerosene oil equivalent to 50,000 mgkg super(-1) and thereafter the field laid out using randomized complete block design (RCBD) with four treatments of 10, 20, 30 tha super(-1) of poultry manure and control which were replicated five times. Maize hybrid (Oba super II) variety was used as an evaluation crop. Results showed except for bulk density, poultry manure amended at 30 tha super(-1 )was significantly (P
