A four-year stationary fertilizer experiment under a rotation system of winter wheat- summer maize and cabbage-capsicum was carried out in couple with systematic analysis of soil nutrients to study soil N, P, K, S, Zn and B supply capacities, balance of N, P, K, gaining or waning of nutrients, and hence rational application rates of N, P, K in croplands and vegetable fields of Hebei. Results show that under the rotation system of wheat-maize, the yield of winter wheat was 7 278～7 475 kg hm^-2in Treatment NPKZnS (CK), and only 50％~52%, 84％~87%, 91％~95%, and 92％~93% of the former in Treatment PKZnS, NKZnS, NPZnS, NPKS and NPKZn, respectively; while the yield of summer maize was 8 396～9 041 kg hm^-2 in CK and only 55％~59%, 83％~86%, 79％~91%, and 89％~94% of the former in Treatment PKZnS, NKZnS, NPZnS and NPKS, respectively. The differences between the treatments were significant. The nutrients as crop yield limiting factors, followed a decreasing order: N > P > K > Zn > S. Apparent N, P and K balance in the soil was maintained by applying 1/2N, 1/2P, and 1/2K For the wheatmaize rotation, 450～500 kg hm^-2 N, 135～150 kg hm^-2P₂O₅, and 90～135 kg hm^-2K₂O was recommended, with P and S applied in wheat season and K and Zn in maize season. In the rotation of Chinese cabbage and capsicum, the yield of Chinese cabbage was 113.9 t hm^-2 in Treatment NPKZnB (CK), and only 57%, 64%, and 87% of the former in Treatment PKZnB, NKZnB and NPZnB, respectively, while the yield of capsicum was 23.7 t hm^-2 in CK, and only 46%, 46%, 68%, 88%, 85% of the former in Treatment PKZnB, NKZnB, NPZnB, NPKB and NPKZn, respectively. Significant differences were observed between the treatments. The nutrients, as crop yield limiting factors, were found to be in the order of N > P > K >Zn> B. For cabbage, the application rate of 200 kg hm^-2 N, 90 kg hm^-2P₂O₅, and 150 kg hm^-2K₂O was, recommended, while for capsicum 300 kg hm^-2 N, 170～180 kg hm^-2P₂O₅, and 400 kg hm^-2K₂O was done. The yield response of capsicum to boron and zinc was also significant.
