Other claims from this paper (16)
- Intervention effect Long-term green manure combined with chemical fertilizer favoured stable and high rice yields.
- Intervention effect Long-term green manure combined with chemical fertilizer reduced the amounts of fertilizer applied.
- Intervention effect Long-term green manure combined with chemical fertilizer raised agronomic efficiency of chemical fertilizer NPK nutrients beyond 60%.
- Intervention effect OM3 (Chinese milkvetch plus pig manure) gave the highest average rice yield over 26 years.
- Intervention effect Average rice yield under OM3 was 64.47% higher than under CK.
- Intervention effect Average rice yield under OM3 was 6.86% higher than under chemical fertilizer NPK application.
- Intervention effect Agronomic efficiency of manure application was 118.9% higher than that of chemical fertilizer NPK.
- Intervention effect Soil organic matter, total N and total P increased under green-chemical fertilizer applications.
- Association Accumulated soil nutrient amounts were related to fertilizer application and manure type.
- Intervention effect OM3 treatment was the optimal treatment for soil nutrients.
- Observation Soil potassium is in deficiency under all treatments.
- Association Total and available soil potassium contents were lower than at the beginning of the experiment.
- Intervention effect Under OM4, available K was 13.94% higher than under CK.
- Intervention effect OM4 treatment was the optimal treatment for soil potassium.
- Association Soil total K had the highest correlation coefficient with rice yield (r=0.808).
- Mechanism K deficiency is the main fertility factor for high rice yield in these paddy soils.
