Chemical weed control in Belize is changing to flaming methods

The methods of controlling weeds by chemicals and adverse expensive products, is turning in Belize, to flame throwers.  The trick apparently is to flame the plot, or land and burn the weeds, about a week after you plant the seeds.  Doesn't touch the seeds and new plants, but gets rid of the weeds, and the charcoal produced enhances the fertility of the soil.  As in ashes.  Good article in AG REPORT issue 18. with a lot more details.  Written by Francesca Camillo.
