Status in Soils Under Different Forest Stands on the Hilly Regions of Southern Jiangsu Province

Abstract: Dynamic properties of nutrient status in soils under Chinese fir plantation, olblolly pine plantation, secondary oak plantation at the same ages of 25 and phyllostachys pubescens plantation on the hilly regions of Jiangsu Province were studied. Results were as follow s: ( 1) Nutrient contents fell at rairly high speed between April and June. It was a suitable season for fertilization. ( 2) From June to August , all the nutrient contents kept stable, so it was a good season for sampling. ( 3) Dynamics of nutrient contents from August to October varied, with available Krising , available P falling , total N keeping unchanging and organic matter keeping stable except oak falling. P fertilizer could be applied to some plantations during this period of time. Comparism of nutrient status in soils of different forest stands was also given.
