Studying soil fertility through the spatial distribution of soil nutrients is necessary for sustainable management of land resources. This investigation was conducted to understand the spatial variability and distribution of trace elements and macronutrients, and soil fertility in agricultural soils by using geostatistics combining with GIS. The sources of' top soil nutrients variability in agricultural...
The spatial distributions and variability of the main nutrients in the topsoil of Chongming island of China are explored by using geostatistics combining with GIS. The multi-scale model is used to analyze the spatial pattern of soil nutrient factors based on the principle of Minimum Nugget Effect to ensure the stability of the interpolation model with the high interpolating accuracy. The result shows...
The leaf nitrogen and phosphorus are considered the major limitations of the photosynthetic process, reflecting the quality and suitability of habitation. The multidimensional factors of ecosystem have been a great barrier to discover the biochemical reaction of plants to their environment. In this research, a novel approach integrated with regression kriging and GIS is applied to explore the pattern...
