Table 3 Chemical analysis of control (S1), soil treated with bacterial suspension (S2) and soil treated with both bacterial suspension and chicken feathers (S3) after 10 days of incubation

From: Ameliorating effects of chicken feathers in plant growth promotion activity by a keratinolytic strain of Bacillus subtilis PF1

  1. Total contents of elements were determined and expressed as grams per 1000 g of soil (ppm), and total C and N were expressed in (%), whereas NO3, P2O5 and K2O were expressed in (Kg/heq.). Results are expressed as a mean of 3 individual experiments. The experiments were performed in triplicate and individual values are depicted as mean ± standard deviation
  2. * Denotes a value significantly greater than the control value (p < 0.05)
