Soil Spatial Variability: Structures, Models, and Their Effects on Crop Yield Variability
Abstract
dc:descriptionPrincipal component analysis showed that only 15 of 51 variables accounted for more than 80% of total soil variability. Component regression accounted for about 52%, and 39% of soybean and corn yields variability respectively. Particle size distribution and organic matter by influencing moisture and nutrient dynamics, were the most important factors determining yield variability in these soils.
