How can I reduce tilling?

Other examples of ways to reduce tillage include:

  1. Using chisel plow shanks, subsoilers or zone-tillers to loosen soil before preparing raised-beds instead of a plow and harrow;
  2. Planting summer cover crops, such as buckwheat, after an early cash crop as a substitute for repeated harrowing to control weeds;

What is the best time to cultivate the soil?
