Composting – Part 2: DIY Compost Accelerator Concentrate

This is part two of my composting series. Here I discuss how to make a homemade compost accelerator concentrate. This recipe is based one of many videos I saw on Youtube but I tweaked it to be more organic. There are other videos and methods for making your own compost accelerator but this video contains a bit of hilarity, which I like and the formulations do cross over. However, if you prefer the method in this video over my suggested recipe, go ahead and use it. Please keep in mind that if you plan to use the compost you make using the video instructions on your edibles, the other chemicals in the products used will also be in your food.

The Recipe

The natural approach that I prefer uses urea aka pure nitrogen instead of ammonia. For his 20 gallon concentrate recipe, you need about 0.5 ounces of urea aka nitrogen to replace the 8 ounces of ammonia. Note: when used for fertilizing purposes, too much nitrogen will cause burning of plants due to the excess salt that is left behind after the water is absorbed by the plants. I have learned through further research that urine, chicken or bovine manure can be used but that is way too natural for my taste. Not to mention that the odor from the manure drive you out of your garden and strain your relationship with your neighbors.  Furthermore, instead of wasting a perfectly good 12 ounce can of beer, I use regular dry yeast. His recipe, depending on the beer, has about 0.09 grams of yeast, which is less than a packet of yeast, that is, if my math is correct. A packet of yeast is usually 7 grams or 1/2 teaspoon. I estimate his recipe requires about one third of 1/4 teaspoon of a packet of yeast. I also estimate that his recipe also uses about 45 grams of sugar depending on the sugar content in both the soda and beer. Instead of soda, I use molasses powder or brown sugar equivalent to 45 grams of sugar. The idea is that the nitrogen breaks down the material with the aid of the yeast which eats the sugar and further aides the decomposition of the composting materials.  Please note that you may or may not need 20 gallons because it depends on your pile, I have made this recipe before and stored it in a cool dark place for a week. I had no issue with it after words. However, if you are unsure about storage or are unable to store it, pour the left-over directly into an unplanted section of your garden.


How to Use

The mixture is incorporated in a lawn sprayer bottle and attached to your hose for use. The other option is to pure the ingredients into a 15 gallon bucket of water and then use a watering can to distribute the mix over the composting materials. Again you can use the bucket method but use a gallon sprayer container to distribute the liquid.  Remember to use a fork or a rake to rotate the composting materials as you add the liquid to your pile or compost bin/tub. I sometimes chuck everything in a contractor bag, leave it on the concrete in the driveway or do it straight in my composter and let it bake in the sun for a minimum of 1 month. I like to do this when it’s warm enough to work out side. This is usually around the end of March so that I have something to put into the garden and my pots by May.  Please note that the temperature, exposure to air and moisture content are important. Too little liquid, air and not enough heat will results in too little decomposition. Too much liquid and not enough heat and air will result is slimy moldy guck. Please note that further ahead in time the process is done the better; especially if the materials are in large pieces and winters are very cold and/or long.
