A review on spatial variability of soil nutrients based on geostatistics

Soil nutrients have high spatial variability because of the combined effects of natural and anthropogenic factors.The research methods on spatial variability of soil nutrients start with traditional statistics and advance to geostatistics and new aided technology,with geostatistics as the most commonly used method at present.This paper discussed about the fundamentals of geostatistics and its applications in spatial variability study of soil nutrients.The status and achievement based on geostatistics at home and abroad were introduced,and the existing problems and the development trends were summarized.
