There are 3 treatments of fertilization : A1 (50 kg KCL/Ha), A2 (100 kg KCL/Ha), A3 (150 kg KCL/Ha), and 5 treatments of fertilizing time : B0 (0 week), B1 (0 and 5 weeks), B2 (0, 5 and 7 weeks), B3 ( 0 and 7 weeks), B4 (5 and 7 weeks). 100 kg/Ha of KCL...
The first factor was combinations of fertilizer and amelioran, i.e., P0 (without fertilization); P1 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite x Aldd (805 kg) ha-1}; P2 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite x Aldd (805 kg) + 1,250 kg of ...
The 100% rate of RDAF applied was: 4 ton dolomite ha-1, 30 ton cow dung ha-1, 150 kg N ha-1 ( Urea + Ammonium Sulfate), 150 kg P2O5 ha-1 (SP-36) and 100 kg K2O ha-1 (KCl). Significant reductions in soil extractable Cd (CdNH4OAc-EDTA) [from 13.35 to 8.77 mg kg-1, ...
