Best Compost Starter Activator For Your Compost Pile

Last Updated on January 16, 2023 by Grow with Bovees

The best compost starters will help to accelerate the composting process production. They can improve the quality of the compost from your compost pile by speeding up the breakdown of organic material, i.e. speeding up the composting process in the pile.

Microorganisms are the key element in the decomposition process of a compost pile and to survive they need two things — carbon and nitrogen.

While everyday wood ash, dried leaves, grass clippings, bread, citrus peels, coffee grounds, corn stalks, some types of paper towels, and myriad other kitchen scraps/food waste are relatively easy to come by to add to your pile, nitrogen-rich composting materials, essential for producing the optimum finished compost, are sometimes lacking in an average compost pile.

So, if you notice that your compost heap isn’t turning into “compost” even after a couple of months, then you need to use some type of compost starter to activate the decomposition process in your compost pile.

There are many composting accessories, accelerators and compost starters on the market, so we decided to investigate them for you and come up with our top seven compost accelerators and activators that will get your compost rocking & rolling in record time!  

1. Jobe’s Organics Compost Starter

Certainly streets ahead in terms of customer satisfaction with compost starters, Jobe’s is also regarded as the perfect all-rounder in the realm of compost accelerators to add to your compost pile.

Jobe's Organics Fast Acting Granular Fertilizer Compost Starter, Easy Plant Care Compost Accelerator, 4 lbs Bag

Jobe’s Organics Compost Starter contains Jobe’s Biozome® which is a mix of two highly beneficial bacteria; Archaea and Mycorrhizal fungi, that work together to increase the quality of the soil by supplementing any lacking in rich materials, which in turn aids plant development and helps combat disease as well as fighting against the negative impact of some insects.

The improvement in soil quality that they contribute to also increases water-holding properties which are particularly beneficial during periods of drought.

Another important ingredient in Jobe’s product is bone meal which helps promote the production of root growth, leading to increased numbers of blooms followed by healthy fruit. This is due to the high and rich content of calcium and phosphorous (in their natural state) contained in bone-meal.

Another less talked about, but nevertheless, highly beneficial ingredient is feather-meal. As the name suggests, this is basically dried feathers (which are 12% nitrogen!) that have been partly ground up under high pressure and high temperatures.

Feather-meal is used as an additive, both in animal feed and in organic soil supplements, due to its valuable nitrogen content.

If one considers that we humans consume more than 25 billion chickens per year, that’s a lot of feathers that could be put to very good use.

Potassium (potash) is another constituent that Jobe’s use. Potassium helps plants to absorb other nutrients as well as aids with transpiration, respiration, and the transport of water through the plant and the function of enzymes, thereby enabling the plant to produce better quality flowers and more flavorful fruits.

The processed manure that is also present increases further the levels of; phosphorous, calcium, potassium, and sulfur along with basic organic matter.

Jobe’s product is OMRI listed for safe organic gardening by the USDA, which means that it is completely free from synthetic materials and very environmentally friendly for your pile.

Made in the USA, the recommended dosage for Jobe’s starter is two cups per cubic yard of organic waste and they recommend adding it to your compost piles every four to six weeks, which may sound a lot, but when you consider the price per pack compared to other brands, it is very good value!

You can also use it in your kitchen countertop compost bucket to start moving the process along before you even add the material to your pile.

Results from this Jobe’s product are very quick and are generally noticeable within two to three weeks. Compare that with normal timescales for pile composting!
