Abstract: To extend the application of Spanish river carbonatite（SRC）,an agromineral fertilizer,in China,a field and a pot experiment were conducted to verify the effects of SRC on the vegetable growth, yield and soil acidification. The filed experiment was divided into two blocks based on the application of chemical fertilizer （+NPK） or not （-NPK）. Under the condition of -NPK and +NPK,SRC with 1 800 kg/hm²（+SRC1 800）could improve the pepper height and stem diameter,yield and soil pH compared to that of without SRC（-SRC）. Under the condition of +NPK, SRC with 900 kg/hm²（+SRC900）could increase yield and pH,but the improvement of yield was lower than that of +SRC1 800, and the improvement of pH was higher than that of +SRC1 800. The pot experiment tested the effects of different SRC：soil （V/V） mixtures （1∶5,1∶10,1∶20 and 1∶40） on cabbage yield and soil pH. As the amount of SRC in the soil was increased, the yield increased compared to that of without SRC as well,and reached 39.9% in the 1∶5 ration. However, although the pH in the SRC soil were increased, the improvements were not positively related to the increase of the SRC amount in soil. In addition, both the filed and pot experiments showed that the improvement of SRC on soil pH was greater in the early stage than in the late stage of vegetable growth. In conclusion, SRC could improve the vegetable growth and yield, and reduce soil acidification.
