Abstract: Nutrient spatial status of three soils in Shandong Province were studied with GPS locating system. Results showed that organic matter contents were widely low in most plough2land of Shandong Province and N nutritients of mostlands were deficient after wheat harvest. Although there were some media and high2P ploughands,but the available Plevels were absolutely low; K nutrients were supplied adequately in plough2land of Shandong Province and there was nodeficiency of potassium. The main nutritient factors which affected quality of plough2land in Shandong Province wereavailable phosphorus and available potassium,then organic matter and alkali2hydrolyzable nitrogen. pH value had the low rest effect on quality of plough2land but soil acidification should be paid more attention. Thus, the production of main plough2lands of Shandong Province can be kept to improve the fertilizer manners and modify the fertilizer ratio adjusting measures to local conditions.

Key words: :Nutritent content , Spatial variability , Three soils, Quality of plough2land , Shandong province
