Abstract Experiment on effects of fertilizer application in protected tomato cultivation on the changes of the contents of soil nutrients and soil salinity under various fertilization models were conducted in the autumn of 2000 and the spring of 2001. The results showed that the application of N at rate of 225 kg·hm -2 with sheep waste at 26.2 t·hm -2 reached the highest yield, but the economically optimum application rate should be below 225 kg·hm -2. Over application of N from urea enhanced water soluble ...
