Plant diversity can add many benefits including:

• Increased pest and disease resistance – it is harder for pests to find suitable host in diverse cropping systems
• Improved soil health – different root structures sequester carbon at various depths in the soil profile and attract/support different microbial communities, including mycorrhizal fungi
• Nutrient cycling – more diverse microbial populations are engaged in the cycling of plant nutrients
• Reduced weed pressure – due to reduction in exposed soil
• Support pollinators – varying flowering times
• Improved biodiversity – wider range of plant, wildlife, microbial, and insects life
