Studies suggest that mixing glycerin in compost boosts the growth of wheatgrass, leading to an increase in shoot harvest and plant height. However, limit the glycerin content to 10% of the compost, more of which might inhibit plant growth.

Another study claims that the use of glycerol ensures high cell density and viability including in harsh environmental conditions.
