Abstract: Soil nutrients often appear great variability in spatial, and their variability characteristic change with the types of soil and nutrient. The variability characteristic of available phosphor of meadow albic bleached soil is analyzed by traditional statistics and geo-statistics technique. The soil samples were collected at two layers(0-20cm and 20-40cm) from a long-term test field in Mishan city Heilongjiang province long-term. The result from traditional statistics shows that the variability available phosphor of meadow albic bleached soil is between moderate and strong degree. The result from geo-statistics shows that the major range of available phosphor of meadow albic bleached soil is 85m around. the radios of nugget to still of to layers is 47.63% and 34.87% respectively, so the spatial correlation of them is between moderate and strong degree.
