-
Management: Hay
Cut to the ground and harvested annually. Non-destructive management systems maintaining the soil organic carbon.
-
Regional Crop
These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits.
