Post-harvest analysis of soil for changing in physical and chemical properties following the addition of biochars with and without N fertilizer.

UN200 = Urea N (UN) applied at 200 mg N kg-1 soil; UN100 = Urea N (UN) applied at 100 mg N kg-1 soil; WCRB30 = White clover residues derived biochar (WCRB) applied at 30 t ha-1; PMB30 = poultry manure derived biochar (WCRB) applied at 30 t ha-1; WCRB15+PMB15 = White clover residues biochar (WCRB) and poultry manure biochar applied at 15 t ha-1 (half) each; UN50+WCRB50 = urea N and white clover residues biochar applied at the proportion of 50:50; UN50+PMB50 = urea N and poultry manure biochar applied at the proportion of 50:50; UN50+WCRB25+ PMB25 = urea N, white clover residues and poultry manure biochars applied at the proportion of 50:25:25. Least significant difference (LSD) P ≤ 0.05 is for comparison of treatment means (within the columns), and the means followed by the same letter are not significantly different from each other.
