Intervention effect NPK plus manure produced the most sustainable grain yields over 41 years.
Observation Optimal and superoptimal NPK yields declined sharply after two decades as zinc deficiency emerged.
Observation Wheat yields were more sustainable than rice yields.
Observation Control soil lost the most organic carbon and available N, P, K and Zn.
Intervention effect NPK plus manure improved available soil N, P and K.
Intervention effect NPK plus manure reduced soil zinc below initial levels.
Association Grain yield and sustainable yield index correlated more strongly with soil organic carbon.
Observation Continuous farmyard manure gave the highest soil quality index of 0.94.
