One was left out.
I will not recommend this strategy but It needs to be considered. Why 
because it has less impact than some of the others, and of your current use 
of the computer you are now using and conviently overlook

to solarise you must first loosen the soil.
plastic sheeting kills all organisms 6 - 8  in deep
Over crops dont work (unlees you do so for years)
chickens dont till deep enough
weed block fabric is easily pierced

all are labour intensive

Bill talks about the appropriate use of technology. some chemicals are toxic 
and residul others not...depends on the "Half" life. Folks use pyrethems and 
Kill aphids, natural yes toxic to some animals YES. So the delemer is what 
has least impact for the most effectiveness.

so now to the "G" word...gylphosphate salts, You cannot get emotionally 
locked up to not use a good tool because it has been abused by idiots.  I 
say "Lets ban the chain saw" we have global deforestation therefore its the 
chainsaw that need banning!!!  Stupid  !!!

Use the right tool the correct way and have "Least effect for the greatest 
yeild".

So use Glyphosphate and follow with Compost Tea and Accumilators, hot 
compost the material and your field is clear in one season, all chems are 
gone and can be followed by a crop

(Compost Tea and Accumilators = bio-remediation turned around as part of a 
strategy)

So go ahead ban you chain saw, your computor, your car, your tractor, your 
TV, your PVC piping, your rockdust, your eye surgery, your.....
