Abstract

This experiment is about the evaluation of characteristic alteration of soil nutrients after ten years at tropical rain forest Bukit Gajabuih Gunung Gadut Padang. This experiment was conducted fi'om November2A06 - April2007. This experiment is arranged basecl on anova design with three treattnetrts which was based on three great groups of land ( oxic-dystrouc/ept (eutriccc, crclr,tic,), oxic- dystroudept (xanthic), oxic-typic-dystroudept (xanthic)). The purpose of this experiment was to study the alteration of soil fertility characteristics (K, Ca, Mg, Na, P and CN) in ten years period (1995-2005) in tropical rain forest at Bukit Gajabuih Padang, to observe vegetatiol variety alteration, and the relatiottship with the larrd fertility characteristics. Frorn the experiment was found that nutrient status of the soils altered after ten years (*1995-2005). Available P content increased about 77yo, exchangeable Na and K increased 86,040A and 53 .65Vo, respectively. Op the other hand, exchangeable Mg and Ca decreased 3,050A and 65,88Yo,respectively. Larrd CN ratio decreased about 21,39yo. The experimental plot had low soil pH.
