WebTillage and nitrogen (N) fertilization systems may affect soil chemical and physical properties, especially long term. This study's objective was to examine the effect of three tillage systems (conventional tillage, reduced tillage, and no-till) with four N fertilizer treatments on properties of a claypan soil in the eastern Great Plains after 20 yr of … WebClaypan is a dense, compact, slowly permeable layer in the subsoil.[1] It has a much higher clay content than the overlying material, from which it is separated by a sharply defined boundary. The dense structure restricts root growth and water infiltration. Therefore, a perched water table might form on top of the claypan.[2] In the Canadian classification …
