Organic Weed Control: 

1. Control weeds with mechanical cultivation
2. Smother weeds with the plant canopy; keeping the soil loose and 
   full of humus helps crops grow fast enough to make this work.
3. Grow the primary allelopathic food crops; wheat, oats, and sorghum.
   These are food crops that also help control weeds.
   But avoid using these crops for mere cover as much as possible, 
   since they are primarily consumed for food. 
4. Primary cover crops / green manure: flax, fava, vetch.
5. Winter barley and rye are not always appropriate as cover crops because 
   they require flowering next year before they can be killed.
6. Use Chinese weeder geese to control grass weeds.
   Portable fencing may be necessary to keep them out of the grain crops.
7. In the fall, after harvest, turn animals out on the stubble to suppress 
   weeds and speed crop residue decomposition.
8. Allelopathic mulch materials: walnut shells, sunflower shells
   Very powerful, so only use on garden borders far from plants.
   Do not use inside the garden.
9. Do not plant invasive or self seeding plants inside the garden:
      (fennel, dill, burdock, jerusalem artichoke, comfrey
      , horseradish, dandelion, etc.)
10. Spreading several feet of extremely fresh manure over the soil 
   and allowing it to decompose for several months will kill all 
   weed seeds in the top several inches.
