Before you start your vegetable garden this summer, dig in some charcoal

This means hardwood charcoal, not charcoal made of coal and not charcoal briquettes or formed charcoal.

Small pieces about the size of fine gravel or grains of corn would be the right size... and the dust would be good too. See if you can find a local charcoal maker. You may also be able to find agricultural or horticultural charcoal in bulk at agricultural supply stores.

You do this once and need never do it again. The soil should improve with each season.
