>The graph for six years appears to be a linear line.
Stan, you are correct in that this one appears linear. One needs to look
at the original data sets from which Goulson created this single graph.
The overall data suggest plateauing. That is why I'm seeking other data
sets, to see if that is a consistent result.

As you know, the half life is strongly dependent upon soil type and the
amount of organic matter, and type of plant life.

Good question, Stan! I'm no mathematician, but let me play with some
graphing to see (my flight is about to board).

Agreed! That's why I'm asking!
