Abstract: The distribution characteristic of alkali-hydrolysable nitrogen was studied by analysis of alkali-hydrolysable nitrogen content in different soil depth of herbal fields and food-crop fields in Anguo city,Hebei province.The results indicated that difference of alkali-hydro nitrogen content in the lands between blocks of herbal fields and food-crop fields was magnitudes,and alkali-hydro nitrogen content was reduced with the increase of soil depth,extremely significant difference (P<0.01).Alkali-hydro nitrogen content of 0-20,20-40,and 40-60 cm in herbal fields and food-crop fields were 39.42,24.02,and 16.07 mg/kg and 37.37,22.88,and 13.20 mg/kg,respectively.Alkali-hydro nitrogen content of food-crop fields was slightly lower than herbal field soils.Alkali-hydrolysable nitrogen content of herbal fields and food-crop fields were in fifth or sixth level according to the soil fertility classification standards of the second national soil survey,and the fertility of soils were low.Therefore,soil nitrogen supplying capacity of herbal fields and food-crop fields were similar,but the soil fertility was low,so more measures should be taken to improved soil fertility,as application of organic and nitrogen fertilizer.

Key words: Anguo city, Available nitrogen, Herbal field, Food-crop field, Soil depth, N-supply level
