Areal Interpolation AND trend

I am attempting to perform an areal interpolation in some demographic data.  The data exhibit a quadratic trend E-W and linear trend N-S.  I suspect that the trend is (in part) the reason why the covariance fitting is not successful. Is there any direct way to de-trend my polygon data prior to the Areal Interpolation?

Thank you in advance.
