Abstract

According to the results of soil testing using GPS in 2010, the paper analyzed the spatial variability characteristics of the soil nutrient index such as organic matter, alkali-hydrolyzable nitrogen, available phosphorous, available potassium, pH value and effective sulfur on the farm scale by the methods of classical statistics and geostatistics, and made geographic cartography based on the above indicators. The paper aimed at clarifying the regulation of the spatial distribution of the soil nutrients in the study area of Fuxingwei farm, and providing theoretical reference for the farm to implement precise fertilization strategy of crops and improve crop production capacity and economic benefits.
