- Observation K, Ca and Mg additions from fertilizer, ash and precipitation for burnt residue with fertilization (LRBF) were estimated at 54.25, 816.68, 103.31 and 23.54 kg per ha.
- Observation Additions for residue removed with fertilization (LRRF) were 35.56, 576.05, 100.17 and 4.93 kg P, K, Ca and Mg per ha respectively.
- Observation Amounts of P, K, Ca and Mg lost under LRBF were 18.44, 300.45, 66.06 and 8.63 kg per ha.
- Observation Losses of P, K, Ca and Mg under LRRF were 23.19, 244.88, 45.79 and 5.49 kg per ha.
- Observation Leaching was the major source of P, K, Ca and Mg loss for both practices.
- Mechanism The authors attribute the leaching loss to inappropriate fertilization frequency.
- Observation LRBF had a positive balance of P, K, Ca and Mg of 46.00% P, 28.00% K, 20.00% Ca and 27.00% Mg, which could be recycled after cropping.
- Observation About 60.00% P, 20.00% K, 13.00% Ca and 36.47% Mg are recycled for LRRF.
