- Intervention effect Fertilizer application decreased alfalfa acid detergent fibre by 2.9% compared with non-fertilized controls.
- Intervention effect Fertilizer application decreased alfalfa neutral detergent fibre by 1.8% compared with non-fertilized controls.
- Intervention effect Combined NPK and combined NP fertilizer applications achieved the greatest alfalfa yield increase, 27.0%.
- Intervention effect Combined NPK and combined NP fertilizer applications achieved the greatest alfalfa crude protein concentration increase, 13.5%.
- Recommendation Considering yield and quality, the optimal nitrogen rate for alfalfa ranged from 30 to 60 kg ha-1.
- Recommendation Considering yield and quality, the optimal phosphorus rate for alfalfa ranged from 120 to 150 kg ha-1.
- Recommendation Considering yield and quality, the optimal potassium rate for alfalfa was less than 120 kg ha-1.
- Association The effect of fertilizer application on alfalfa yield was greater in low soil organic matter soils than in high SOM soils.
