I totally agree about the importance of soil.

The soil is alive, and I'm sure there is an effect on plants. (Well, it's no longer alive when chemical pesticides and fertilizers are used, killing the micro-organisms; I meant in a more natural farm setting.) I'm not a fan of hydroponics. Still, what are the tradeoffs for a country like Singapore? Fresh, soil-grown local produce isn't an option. They simply don't have the farmland. So I think vertical farming there is a great idea.

When we try to pick out anything by itself, we find it hitched to everything else in the Universe.
