Abstract
Controlled Release Nutrient sources assist in the bioremediation of hydrocarbon spills by stimulating microbial activity. However, freeze-thaw activity might result in splitting of fertilizer pellets with the uncontrolled release of nutrients. We examined the role of freeze-thaw and three moisture levels on nutrient release from MaxBac®, a nitrogen and phosphorus-based fertilizer encapsulated by an organic resin. We found that moisture alone accounts for most of the nutrient release, while freeze-thaw creates only a minor enhancement of nutrient release. This Controlled Release Nutrient source appears to be suitable for use in areas of freezing ground.
