High residue mulch, living or dead, improves weed suppression by capturing growth inputs, particularly light. We want the plants to basically germinate very quickly and close the canopy. Drip irrigation is also a very useful weed control strategy. Placing water near the roots of the vegetable crops and not irrigating the adjacent weeds, we have found it to be very efficient. In some cases, you have such a serious weed infestation, that before you enter into a no-till system, it’s probably beneficial to spend a year or even two years to grow cover crops that are known to minimize weed pressure. Two of the crops that we have used successfully are sorghum-sudangrass and also buckwheat.
