Change in soil NH＋4 ‐N and NO－3 ‐N under different land use types in the Longzhong part of Loess plateau

摘要：

Nitrogen is a limiting element for plant growth in many ecosystems.Inorganic N (NH＋ 4 ‐N and NO-3 ‐N),in soil is the primary N pool available for plants.The availability of these different N forms can change depending on types of land use (Antonio Gallardo et al, 2005).The purpose of this study was to research the effect of different land use types on soil N.
