  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)
