The previous poster is looking at real-life issues, and doubtless

cost/benefit analysis appears to have come down on the side of
manufactured fertilizer. Makes sense to me. He's not talking about
wholesale DDT spraying, or lowering the water table to keep his
golfcourse green.

One factor rarely included in the cost/benefits analysis is the problem of
possibly running out of fossil fuels(which is where many of the chemicals come
from). It's kind of hard to establish a value for that, but it might be
important somewhere down the road.
