A couple of weeks ago, we initiated testing of our 2^nd generation prototype band-steam machine. Band-steam is where steam is applied in narrow bands of soil centered on the seedline to raise temperatures to levels sufficient to kill weed seed and soilborne pathogens (140°F for 20 minutes). The machine has a higher capacity steam generator and simpler design than our first prototype. Check it out by clicking here or on the image below.
