To explore expression of nutrients productivity of the soil per se, a 13-year stationary fertilization experiment on soil nutrient depletion was carried out in fluvo-aquic soil under a winter wheat (Triticum aestivum L.)–maize (Zea mays L.) double cropping system in Xiongxian County of Hebei Province. The experiment was designed to have eight treatments, namely control (no fertilizer applied), complete fertiliztion, and complete fertilization except N, P, K, Mn, Zn, or B alternately, and “sustaining yield” was used as the index of soil nutrient productivity. Results show that the sustaining yield of soil N, P, K, Zn, Mn, and B was 2 553, 3 918, 5 668, 6 571, 6 871, and 7 353 kg hm^-2 for wheat, and 2 280, 4 576, 6 875, 8 788, 9 465, and 9 188 kg hm^-2 for maize, respectively. The lower sustaining yields of soil N, P, and K showed high possibility of yield promotion through lifting their respective nutrient barrier. Regarding the selfbalancing and recylcing ability, the six soil elements followed an order of N < P < K < Zn < Mn < B in the wheat cropping season, and N < P < K < Zn < B < Mn in the maize cropping season. The sustainable yield indexes (SYI) of the eight treatments show that the complete fertilization treatment was the highest in soil nutrient productivity, whereas the rest were much lower because of imbalance of nutrient supply with Treatments N₀ and P in particular.
