Growing a variety of crops and beneficial plants not only acts as a hedge against the falling price of a particular crop but also creates an ecosystem for predators, helping control pests, keeps diseases from destroying the whole harvests, and form pollinator habitats. What's more, having diverse roots in the ground, which exists in polycultures rather than monocultures, provides a variety of food sources for microbes--supporting biodiversity below ground . This type of biodiversity increases soil sequestration capability and creates different soil pore sizes, enabling efficient carbon storage .
