The effects of fertilization on soil water and wheat yield was carried out in dry land of Loess Plateau based on the long-term fixed experiments. The results showed that there were no significantly differences on the distribution of soil water in the single chemical fertilizer treatments. Single manure and the combination of fertilizer enhanced the water absorption of wheat from the deeper layers, which resulted to the decrease of soil water pondage. Of all the treatments, the pondage decreased by 28% in the NM treatment, 24%in the NPM treatment, 21% in the M treatment and 20% in the PM treatment. The wheat yields were significantly different in the different fertilizer treatments. The yield increased by more than 75% in the single manure and the combination of fertilizer treatments, and in the NP, M and PM treatments were more than 90%. The highest water use efficiency was in the PM treatment, increased by 106.6% compared to the control.
