Rejuvenate was originally developed to speed up residue digestion. Once it was discovered how rapidly the product stimulated soil biology and released nutrients from the soil, growers began using it in-season with some very good crop responses.
The intent was to develop a microbial stimulant that would lead to rapid residue breakdown without added purchased nitrogen. When purchased nitrogen is added, much of the carbon in the crop residue is lost to the atmosphere as CO2. While we do want to cycle large volumes of carbon and have CO2 release to the atmosphere, we only want this to occur when green photosynthesizing plants are present that are capable of capturing it once more.
When Rejuvenate is added, crop residue breaks down very quickly and is captured as organic matter in the soil, and can be released during the following peak photosynthesis period.
This is a set of comparison photos of corn residue treated and untreated with Rejuvenate five days after application. In the treated section, the center pith of the stalks has already turned black, while the untreated side is still white.
