This diagram illustrates the principles of the no-till system concept. Key components of the system are placed around the perimeter. They are:

• Soil Management
• Residue Management
• Planting Equipment
• Weed Control
• Insect Management
• Disease Management
• Nutrient Management
• Crop Rotation
• Cover Crops
• Varietal Selection

The arrows in the diagram point in both directions to show that each component affects the whole system - and the system affects each component. (Each component is interactive.)
