There is software around which will allow you to define different nugget effects in different directions, but I would not put any bets on the outcome!
It looks like you have a short range component which cannot be seen because of the spacing of your data. Try adding a spherical component with a shorter range and a component sill of the right size to make the nugget effect equal in all directions. I would.
