D-Comp · Fall residue biology

Make last season feed the next one.

Apply D-Comp to post-harvest residue to help accelerate breakdown and move nutrients held in stalks back into the soil's nutrient cycle. D-Comp's powder formulation mixes with water and can be applied with standard spray equipment.

A visible field comparison

More exposed soil. Less intact residue left standing.

In this treated-versus-untreated field comparison, the D-Comp-treated area shows more exposed soil and less intact residue. D-Comp helps accelerate residue breakdown so nutrients held in stalks can return to the soil's nutrient cycle.

Decompose
Help break down tough plant fibers such as lignin, cellulose, xylans and pectin.
Recycle
Help return nutrients held in residue to the soil's active nutrient cycle.
Apply
Mix the powder with water and surface-apply it after harvest with standard spray equipment.

How D-Comp works

Residue is a team job. D-Comp brings the full crew.

Different biological tools take on different parts of decomposition, with one fall goal: move nutrients from residue back into the soil cycle.

01

Fiber-decomposing enzymes

Start opening complex plant material.

Fibrolytic enzymes help catalyze the first steps of residue breakdown.

02

Bacteria + fungi

Keep fermentation moving.

Multiple strains work together on lignin, cellulose, xylans and pectin.

03

Nutrient cycling

Help return residue nutrients to the soil cycle.

Together, the biological process helps move nutrients held in residue back into the soil cycle.

Quick question

How much residue can a 200-bushel crop leave behind?

More than 4 tonsof crop residue per acre.

Why it matters

When residue does not break down, it can work against the next crop.

That residue is more than material left on the field. When it remains intact, it can keep valuable fertility tied up, interfere with planting and the performance of the next crop and leave the seedbed in poorer condition.

01

Fertility stays tied up.

Undecomposed residue can immobilize valuable nutrients in plant material instead of moving them back into the soil's nutrient cycle.

02

Planting has more to fight.

Heavy, intact residue can interfere with planting performance, seed placement and establishment of the following crop.

03

The seedbed loses consistency.

Excess residue can make the seedbed harder to manage and reduce the uniform field conditions needed for the next crop.

How D-Comp helps

Turn excess residue into a resource for the next crop.

D-Comp uses natural enzymes and aggressive residue-decomposing organisms to attack tough plant material. This biological team helps reduce the residue load, release fertility tied up in stalks and improve seedbed conditions for the next crop.

  • Break down plant material
  • Reduce surface residue
  • Release tied-up fertility
  • Improve seedbed conditions

Fall application

D-Comp's powder formulation mixes with water and can be applied with standard spray equipment.

Timing

Apply to surface residue after harvest.

Mixing

Mix with water or compatible biologicals.

Target acres

Prioritize acres with heavy post-harvest residue.

Equipment

Use standard spray equipment for the fall pass.

What crop material does D-Comp target?

It is designed to help break down tough crop residue, including plant fibers such as lignin, cellulose, xylans and pectin.

When should it be applied for this program?

Apply D-Comp to surface residue after harvest. Your Direct Biologicals specialist can help identify the right fall timing for your acres.

How is the powder formulation applied?

Mix D-Comp with water or compatible biologicals and apply it with standard spray equipment.

Can I mix it with chlorinated water?

Chlorinated water is likely harmful to the biology. Well water is preferred, or use a suitable dechlorinating agent when rural water is the only option.
