rane performed terrible, just total N in the soil was much better (and cheaper). I was wondering what your experiences were. Sorry to divert a bit from the main topic of this list JW. Jan Willem van Groenigen University of California - Davis Dept. of Agronomy and Range Science 1 Shield Avenue

AI-GEOSTATS: Samples in a block

ctly what makes it interesting for sampling optimization, since you don't have those values before sampling anyway However, the last of my references used an optimization criterion that doesn't involve kriging variance. Cheers, Jan Willem. *****************

ional sampling scheme for minimal kriging variance. Also, the spatial simulated annealing algorithm would allow me to make full use of the first stage samples. Hope this helps, JW. ****** Jan Willem van Groenigen University of California - Davis Dep
