摘要: Precision Agriculture requires a method of gathering information about the spatial variability soil that reduces need for expensive and intensive sampling. This can be achieved through use what we term 'average' 'proportional' variograms. A literature search has enabled variograms multiple properties, allowing comparison magnitude construction averages. For properties display proportionality between their mean squared variance, variogram predicted from value. These average proportional are potentially beneficial to implementers as they used plan optimal sampling management schemes. It was found if wishing implement site-specific resolution 20×20 m then grid will generally have performed at 20–30 intervals depending on attribute interest. decision-support chart differential based variogram's comparative is presented. Further work needs done increasing data base these results refining parameters site-specificity.
