Abstract
Fast pyrolysis is optimized for production of bio-oil. Product yields are typically ~65% bio-oil, 20% biochar, 15% syngas.
Project Objective
To investigate N, P, K, and S dynamics in a comprehensive residue removal, tillage, and nutrient management study
Project Treatments
*Residue removal: 0, 50%, 90%
*Tillage: chisel plow, no-till
*Nutrient management: conventional (30K plants/A), high input (44K plants/A)
•Bio-char: 0, 4.32 tons/A, 8.25 tons/A
•Cover crops: annual, perennial
2009 Soil Test Levels
2009 Nutrient Management
Field Measurements
•Stand counts
•Whole-plant samples at V6
•Ear-leaf samples at mid-silk
•Grain yield and moisture
•Stover yield and moisture
•Grain and stover nutrient content
