Stop feeding the residue first
Accelerated fiber breakdown helps reduce the window when residue competes with the crop for available nitrogen.
Enzymes + bacteria + fungi
Today's residue is next season's opportunity.
D-Comp Dry helps break down stalks and fiber faster, so more of the nutrients in last season's residue can cycle back into the soil. That means less residue in the way of seed placement and a cleaner start for the next crop.
Build a cleaner seedbed and recycle more nutrients.
What it targets
Tough stalks, lignin, cellulose, fiber, and other leftover plant material.
Where it fits
Spring residue, post-harvest residue, in-furrow programs, and manure applications.
How it applies
A powder formulation that works with standard spray equipment and your current field routine.
Cold-weather activity
Proprietary organisms are designed to keep residue cycling at temperatures as low as 34°F.
When residue breaks down too slowly
Too much residue can cost you twice.
Leftover stalks can hold nutrients and get in the way of seed placement. D-Comp Dry helps break them down faster, so those nutrients can return to the soil and the next crop gets a cleaner start.
Give every seed a better start
Less stubborn surface material can support more consistent seed placement, contact, emergence, and stands.
Keep more value in the field
Microbial cycling converts decaying plant material into food for the living soil and plant-available nutrient pathways.
How D-Comp Dry works
Four moves from residue to resource.
The science is sophisticated, but the field benefit is simple: help microbes break down tough fiber, feed the soil, and keep nutrients cycling.
-
1
Apply where the residue is
Apply D-Comp Dry to crop residue after harvest or before planting, or add it to your in-furrow program.
-
2
Enzymes open tough fiber
Fibrolytic enzymes help get the breakdown of lignin, cellulose, xylans, and pectin moving.
-
3
Microbes keep the process going
Multiple strains of bacteria and fungi ferment the material and build active microbial biomass.
-
4
Nutrients return to the cycle
Beneficial microbes help make recycled nutrients more available to the next crop.
Three practical ways to use D-Comp Dry
Use D-Comp Dry on residue, in-furrow, or with manure.
Residue
Clean up the seedbed
Spray directly on crop residue in fall or spring to get tough material breaking down sooner.
In-furrow
Put biology beside the seed
Use D-Comp Dry in-furrow to support mineral solubilization, nutrient access, and a more even start.
Manure
Move more manure value to the field
Help break down undigested fiber, protein, fat, and starch while improving nutrient availability and composting efficiency.

Why a warmer reading can matter
More warmth can keep soil biology working in cool conditions.
Active soil microbes help break down residue and recycle nutrients. When the soil is cool, a warmer zone can support that activity and help prepare a cleaner seedbed for the next crop.
At the measured points, the D-Comp area read 69.6°F and the untreated area read 64.2°F—a 5.4°F difference. This is one field observation, not a controlled trial or yield guarantee. Temperature changes with timing, depth, location, weather, and field conditions.
Straight answers for the field
Questions growers ask about D-Comp Dry.
How is D-Comp Dry applied?
D-Comp Dry is a powder formulation that can be mixed with water or compatible biologicals and applied with standard spray equipment. It can be surface-applied to residue after harvest or in spring, used in-furrow, or applied with manure according to product directions.
Why not just wait for residue to break down naturally?
Natural decomposition can be slow, especially with tough fiber. D-Comp Dry concentrates the enzymes and microbes that attack that material, helping shorten the time residue can tie up nitrogen or interfere with the next seedbed.
Can D-Comp Dry be used with manure?
Yes. It helps break down undigested proteins, fats, starches, and fiber, while supporting nutrient availability and a faster, more efficient composting process.
How quickly should I expect to see a difference?
Growers may notice residue softening and breaking down and soil texture changing as the season progresses. Results depend on residue load, moisture, temperature, timing, and management.
Can I mix it with chlorinated water?
Chlorine can harm biological activity. Well water is preferred. If rural water is used, apply a suitable de-chlorinating agent in accordance with product specifications and your Direct Biologicals representative's guidance.
