Other claims from this paper (17)
- Intervention effect Rice yield was highest with 25%- 50% organic N.
- Intervention effect At 25%- 50% organic N, average rice yield was 5. 1% higher than with all chemical N.
- Intervention effect At 25%- 50% organic N, average rice yield was 44. 9% above the unfertilized control.
- Intervention effect Rice yields did not differ significantly between 25% and 50% organic N.
- Association Soil organic matter content increased as the organic fertilizer ratio increased.
- Association Soil carbon management index increased as the organic fertilizer ratio increased.
- Association Total organic matter content correlated positively with chicken manure application ratio.
- Association Mid-labile organic matter correlated positively with rice yield.
- Association High-labile organic matter had no significant correlation with rice yield.
- Association Labile organic matter had no significant correlation with rice yield.
- Association Total organic matter had no significant correlation with rice yield.
- Intervention effect Increasing chicken manure rate improved exchangeable soil base cations.
- Intervention effect Increasing chicken manure rate raised soil cation exchange capacity.
- Intervention effect Increasing chicken manure rate raised soil pH.
- Association Soil buffering capacity increased with chicken manure ratio and ranged from 2. 07 to 2. 36 cmol /kg.
- Association Cation exchange capacity correlated positively with organic matter content.
- Recommendation The recommended manure N substitution ratio is 25% to 50% for favorable soil properties and yield.
