Microorganism-based starters: These starters contain a mix of beneficial bacteria and fungi that naturally occur in healthy compost. They help jumpstart the decomposition process by introducing a diverse range of microorganisms to the compost pile.

Manure-based starters: Manure from herbivores, such as cows, horses, or chickens, is rich in nitrogen and beneficial microorganisms. Using manure as a composting starter can provide a good source of nutrients and microbes that speed up decomposition.

Green waste-based starters: Green waste, such as freshly cut grass, plant trimmings, or vegetable scraps, can be used as a composting starter. These materials are high in nitrogen and moisture, which promotes microbial activity and accelerates composting.

Compost tea: Compost tea is a liquid extract made by steeping compost in water. It contains beneficial microorganisms and nutrients from the compost. Adding compost tea to the compost pile or directly to the soil can help enhance microbial activity and speed up decomposition.

Yeast-based starters: Some composting starters contain yeast cultures that aid in breaking down organic matter. Yeasts can help accelerate the composting process by boosting microbial activity.

Enzyme-based starters: Enzyme-based composting starters contain enzymes that help break down complex organic molecules into simpler compounds. These enzymes can help speed up decomposition and improve nutrient availability in the compost.

DIY Compost Starters

If you prefer to make your own compost starters or activators at home, there are several DIY options you can try. While these homemade starters may not be as concentrated or potent as commercial products, they can still provide a boost to your compost pile.

Here are a few DIY compost starters you can make:

Compost tea: Create a homemade compost tea by steeping a shovel full of mature compost in a bucket of water for 24 to 48 hours. Stir the mixture occasionally. Strain the liquid and use it to water your compost pile or spray it directly onto the compost to introduce beneficial microorganisms.

Activated compost: If you have already produced compost, you can use a small amount (around 10%) of mature compost to “activate” a new pile. Incorporate the mature compost into the fresh pile to introduce microorganisms and kick-start the decomposition process.

Yeast mixture: Dissolve a packet of active dry yeast in a gallon of lukewarm water. Add a tablespoon of sugar or molasses to feed the yeast. Let the mixture sit for a few hours until it becomes frothy. Dilute the mixture with water and sprinkle it over your compost pile to introduce yeast cultures that aid in decomposition.

Grass clippings: Freshly cut grass clippings are high in nitrogen and can serve as a natural compost activator. Layer a thin amount of grass clippings into your compost pile to provide a nitrogen boost and help speed up decomposition.

Worm castings: If you have a vermicomposting system or access to worm castings, sprinkle a handful of worm castings into your compost pile. Worm castings are rich in beneficial microorganisms and can help stimulate decomposition.

Remember that these homemade compost starters are supplemental and should be used in conjunction with proper composting practices, such as maintaining the right moisture levels, turning the pile regularly, and balancing carbon and nitrogen ratios. The ultimate goal is to create a balanced and diverse microbial ecosystem within the compost pile, which will naturally facilitate the breakdown of organic matter.

Choosing the Right Composting Starter

When you decide to start composting, selecting the right composting starter is essential. In this section, we’ll guide you through assessing your compost needs and matching materials to your compost, so you can choose the best starter for your situation.

How to Use Composting Starters

Here are some essential techniques to get you started successfully.

Layering Technique

To begin with, make sure to layer your compost materials properly. Here’s a simple method to follow:

1. Start with a layer of coarse material at the base of your compost pile. This can include twigs or straw, which helps provide airflow.
2. Add a layer of green materials, such as grass clippings, vegetable scraps, or coffee grounds. These are rich in nitrogen and help accelerate the decomposition process.
3. Follow it up with a layer of brown materials, like dry leaves, paper, or wood chips. These provide carbon and help balance the nitrogen from the green materials.
4. Sprinkle some compost starter on top of this layer. The recommended amount is usually mentioned on the packaging.
5. Repeat these layers until your pile reaches a height of 3-4 feet. Make sure to end with a brown layer to reduce odors and deter pests.

Remember to maintain moisture levels in your compost by occasionally watering the layers.

Proportions and Mixing

It’s crucial to maintain a proper balance between green and brown materials in your compost. The ideal proportion is roughly:

• 3 parts brown materials to
• 1 part green materials.

This ensures a good carbon-to-nitrogen ratio and encourages faster decomposition. Periodically turn and mix the compost using a pitchfork, shovel, or other tools to aerate the pile and help distribute the compost starter evenly. Mixing should be done every 1-2 weeks for optimum results.

Environment, moisture, and materials used will all play a part in the composting process, so monitoring the progress and making adjustments as needed will help your compost pile thrive. Happy composting!
