"What makes identifying the problem
somewhat complex is the fact that it may
take three full years to see the whole picture
of total effects from any lime applied
on a field. If too much is used, it is not
normally noticeable in the first year. In
fact, if any lime was really needed, improvements
will be most evident in the
first year. But by the third year, when
problems are more likely to begin showing
up, many growers have already forgotten
the possible long-term effects of
the limestone application, and tend to
place the blame elsewhere (on weather,
fertilizer, seed, and so on)."
