This study was conducted to investigate the effects of long-term located fertilization on forms distribution of soil calcium in protected field.The results of the study indicated that: Applying organic fertilizer could increase the supply of soil calcium.Apply nitrogen fertilizer affected total calcium content and formation distribution in soil.Adding nitrogen fertilizer application could increase the content of water soluble calcium and decrease the content of total calcium
