How much can be sustainably

removed from the landscape?

Volumes Available Implications

Sustainably Available

• Soil Organic Matter Levels

• Soil Erosion Protection

• Cost and Depletion of Nutrients

• Long term productivity

Practically Available

• Cost And Logistics of Harvest / Storage /

Transport / Processing

• Competing Uses Of Crop Residues / Biomass
