Hi,

Perhaps I would say that to conducte a geostatistic interpolation a best 
as possible, it's missing an anysothropy analysis before choosing to fit 
a model to your semi-variogram. Looking to your primary results, it 
seems that there is variance gradient North-South, so that perhaps the 
variogram have to be construct to take it into account if exists.
