Intervention effect Fertilization raised shoot carbon-to-nitrogen ratio by 8.24% relative to CK.
Intervention effect Most fertilization treatments increased shoot phosphorus concentration by 4.63%.
Observation Shoot nitrogen-to-phosphorus ratios exceeded 23 under most treatments.
Intervention effect Nitrogen and combined fertilization lowered shoot nitrogen-to-phosphorus ratio relative to CK.
Intervention effect Fertilization increased soil carbon only in 2014.
Intervention effect Fertilization had no effect on soil nitrogen.
Intervention effect Phosphorus fertilization increased soil phosphorus content by 34.53% in 2014.
Intervention effect All fertilization increased soil phosphorus by 124.32% at the second cut in 2015.
Association Shoot and soil carbon-to-phosphorus and nitrogen-to-phosphorus ratios changed opposite to phosphorus levels.
Mechanism Phosphorus change largely drove stoichiometric changes after fertilization.
Observation Alfalfa growth on the Loess Plateau was severely phosphorus-limited.
Recommendation Increasing nitrogen or combined fertilizer is recommended to increase alfalfa biomass and alleviate phosphorus limitation.
