Effect of Experimental Blocking on the Suppression of Spatial Dependence Potentially Attributable to Physicochemical Properties of Soils

Abstract: One of the basic principles of experimental design is blocking, which is an important factor in the treatment of the systematic spatial variability that can be found in the edaphic properties where agricultural experiments are conducted. Blocking has a mitigating or suppressing effect on the spatial dependence in the residuals of a model, something desirable in standard linear modeling, specifically in design models. Some computer programs yield a p … Show more

“…Spatial regression models, in addition to allowing the establishment of relations between the variables of interest, allow the variability of spatial dependence to be included in the analysis. This is of great importance because ignoring this factor could lead to biased estimates in the results for the presence of spatial dependence indicates the existence of a functional relation between two locations in two different places; the assumption of independence of the residuals of classical statistics would not be met (47,48). Applications of these models include environmental issues related to particulate pollution and the nitrogen footprint of food (47,49).…”
