Process: Bury Flat Biomass (P 25)

This process specifies distribution and the degree to which crops and/or residue are buried. There are "burial coefficients" specified for each type of "residue," on the basis of its "toughness/size." The five types of residue classes are specified under Flatten Standing Biomass. The burial distribution pattern by depth is specified based upon the Bury Biomass Flag values. The five types of burial distribution patterns are:

Uniform
Biomass is buried uniformly by depth.

Mixing and Inversion
Biomass is inverted and mixed during burial.

Mixing
More biomass is buried near the soil surface.

Inversion
Biomass buried at bottom of tillage zone.

Lifting, Fracturing
Biomass is buried similar to a chisel plow.

Its parameters are:

Burial Biomass Flag
Specifies the type of burial distribution:
• 0: Compression Burial Distribution
• 1: Inversion Burial Distribution
• 2: Lifting, Fracturing Burial Distribution
• 3: Mixing and Inversion Burial Distribution
• 4: Mixing Burial Distribution
• 5: Uniform Burial Distribution
