Central Guizhou Province

where the economic development is being promoted

is receiving an influx of rural labor workers. The dependence of the rural population on land is declining. Consequently

some areas that had become rocky and desertified are in a process of recovery. With this background

the author gathered soil samples of surface layers and carried out chemical analyses. The results show: the accumulated quantity of soil organic matter and N is higher

and it is highest in areas without obvious rocky desertification and lowest in areas with moderate desertification evident. Bedrock material slightly influences the variation in total P and K. The amount of rapidly available N and K is high

while the amount of rapidly available P is very low.
