Abstract: The change of soil nutrition in 1993 to 2003 yearwas surveyed. The status and distribution of soil nutrition in the apple orchard were also studied in the south and central part of Hebei p rovince. The main result showed that organic matter and total N gave an increase of 2.548 and 0.317 mg·kg- 1 during 10 years, respectively. Alkali-N, avail-P (Olsen-P) , avail2K were increased 17.1, 122.3 and 279.5 mg·kg- 1. A-vail-Fe, avail-Zn , avail-Mn gave an increase of 9.2, 1.9 and 10.5 mg·kg- 1. The change of soil nutrition was significantly different between crop fields and apple orchard. Avail-Cu increased significantly. Most of soil nutrition were accumulated in the soil p rofile of 0 - 40 cm, with a little increase in the soil profile of 40 - 80 cm. The soil nutrition accumulation gradually decreased with the soil depth. The soil nutrition also gradually decreased with the increasing distance from the tree trunk. The amount of soil nutrition accumulation was: Olsen-P > avail-K > alkali-N > total N and organic matter.

Key words: Apple, Orchard, Soil nutrition, Accumulation of nutrition, Distribution
