|ALKEN® BIO-NUTRIENT 4 is a
highly soluble, rapidly absorbed nutrient amendment, designed to enhance
bacterial metabolism of chemical pollution for soil bioremediation projects.
Contains ammonium phosphate and ammonium chloride as primary nutrient ingredients.
Dicyandiamide is included, to inhibit the oxidation of positively charged
ammonium ions into negatively charged nitrate-ions by natural soil-resident
nitrifiers (Nitrosomonas, Nitrobacter, Nitrospira or Nitrosococcus). Positively-charged
ammonium ions will be retained at the treatment zone, available to feed
the bioremediation cultures remediating the high levels of polluting organic
carbon, deposited into the soil. If nitrifiers are allowed to convert ammonium
to negatively-charged nitrate ions, nitrate binds with rainwater runoff,
contributing to eutrophication and loss of dissolved oxygen in receiving
waters, causing algae crashes, etc., or can bind with groundwater, causing
potential health issues for mammals consuming nitrate in drinking water.
This formula includes micro-nutrients (vitamins, minerals, trace elements
and amino-acids) to ensure that any elements missing due to mismanagement
of soil prior to the specific incident of pollution, are provided.|
If the petroleum compounds appear to be tightly bound to clay, rocks, sand or other soil particles, addition of ALKEN CLEAR-FLO® 5100 should be considered, both for the enhanced biodegradability of the chemical surfactants in the product, but also for the stabilized Bacillus endospores that target secondary metabolites, including the long-chain fatty acid secondary metabolites produced during petroleum bioremediation

|Since soil bioremediation projects are often fairly large, Alken-Murray will prescribe this product based upon the nutrient deficiencies in the contaminated soil at the treatment site. The ratio of nutrients that best enhances degradation of petroleum hydrocarbons and other challenging compounds is C (Total organic carbon present) to N (preferably ammonia-nitrogen to P (soluble or ortho-phosphate) is 100 to 10 to 2, as compared to the ratio suggested for digestion of food waste or sewage, which is 100 to 6 to 1.2. Both use the same 5 to 1 ratio of ammonia to nitrogen, but higher nitrogen is required for degradation of petroleum hydrocarbon compounds (and other challenging organic compounds, like surfactants, ketones, phenolics, cyanide, etc. The nitrification inhibitor and micronutrients are included so that the dosage will be correct when you calculate the required primary nutrients (ammonia and phosphate) needed to balance the concentration of TOC (Total Organic Carbon) present.
