The “granddaddy” of crop residue digester products is Residuce, by AgriEnergy Resources. It has been widely and successfully used about 30 years. With all that field experience, AgriEnergy has been able to adjust the microbe mix for versatile use on any crop or soil.
Oct. 8, 2017 — Following is a message sent by AgriEnergy a few days ago to its clients, reminding them that residue decomposition is useful on other crops besides cornstalks:
Using biology in the fall has its benefits in perennial crops like hay and pasture.
AgriEnergy’s Residuce® program has shown to help break down harvest residue more quickly. Applying right after the final cutting of hay, or in early fall, gives beneficial bacteria and fungi more time to work.
Residuce®, along with abundant soil moisture over the winter, will trigger decomposition and lead to a mellower seedbed next spring. Soil warms up fast because residue has begun to darken and crumble. The greater your soil biology activity, the greater your soil productivity and fertility effect will be. This gives your soil a head start on next year’s crop.
Nearby is a picture of a Michigan hay field where Residuce® was applied. Residuce®, along with a carbon source, can show dramatic results such as faster green-up and thatch breakdown.
The treated strip shows Residuce®, compared to the untreated where nothing was applied. The treated strip allows moisture and nutrients to easily absorb into the soil. Water holding capacity is also a benefit, as well as converting thatch to recaptured carbon instead of just letting it weather away.
Here’s a close-up of the untreated strip: lots of trash and thatch soaking up moisture; reducing infiltration of moisture going to the roots.
Compare that untreated field with this close-up of the side treated with Residuce: very clean, very little thatch, lots of hay growth, moisture is able to soak directly into the soil and root bed.
