- Intervention effect K fertilization greatly increased alfalfa yield and persistence over nine years.
- Intervention effect N and P reduced alfalfa persistence.
- Association Rainfall, rather than P fertilizer, determined P concentration in alfalfa hay.
- Intervention effect K and P fertilization influenced soil K and P supplies.
- Association Continued alfalfa production depended largely on the relative abundance of fertilizer K.
- Observation Soil P supply was sufficient for maximum alfalfa yields.
- Observation Soil P supply depleted without P application.
