Compost And Soil Sifter: The Ultimate Guide
A compost sifter will come in handy after your compost has matured, whereby you will need to sift out the more massive woody or compost crumps that need to biodegrade further. As a result, your plants get readily available nutrients from the compost, and the fine particles are much easier to apply or use as a top dressing. This guide will take you through what a sifter is, how to use one, types of sifters, why to use one, and where to buy the best compost and soil sifters.
What Is A Compost And Soil Sifter?
A compost sifter relies on a piece of hardware cloth that’s made of galvanized steel to sift soil and compost, allowing only small-sized particles to pass through. A compost sifter comes in handy when dealing with fresh compost that still contains large crumbles of organic matter that could harm delicate shoots while applying the compost to your plants. While you can opt for a prebuilt sifter from the stores, it's much quicker and cheaper to build a DIY compost sifter using locally available materials.
Why Use A Sifter?
1. Uniform Compost
You can use a compost sifter to sift out the compost leaving behind finely ground particles of compost that have a uniform size. Uniform compost is much easier to apply, and it easily mixes with the topsoil to deliver the nutrients to your plant’s roots.
2. Sift Out Larger Pieces That Require More Time To Fully Compost
The large pieces of woody material or organic matter that still requires more time to decompose can be easily sifted out with a compost sifter. These larger pieces serve a dual role in that they help inoculate fresh piles of compost materials with bacteria and fungi responsible for the decomposition process.
3. Easier To Apply
Finely sifted compost is much easier to apply as it contains small particles that can be distributed as required. The uniform compost also makes it much easier to spread around the garden compared to large clumps of still-decomposing organic matter.
4. More Readily Available Nutrients
Finely sifted compost delivers more readily available nutrients for your plants to absorb. The smaller size of the particles also means they are much easier to mix in with the topsoil allowing water to carry the nutrients down to the roots in naturally controlled amounts.

Considerations When Buying A Soil Sifter
1. Materials Used
When shopping for a compost sifter, it's recommendable to go for ones built with high-quality materials such as galvanized steel. Avoid plastic-based sifts as they will wear out much faster than the standard hardware cloth that's made of stainless steel. The frame should also be high quality to withstand prolonged use; it preferably should be made of a hardwood frame or a stainless steel one.
2. Size of The Sift
The size of the sift will determine how much compost you can sift through it at any given time. If you are looking to sift a small batch of compost, it's much more affordable to get a small-sized compost sifter instead of a large one that's more suited for large scale sifting jobs.
3. Cost
The cost of a compost sifter will vary depending on the build quality and additional aesthetics. While shopping for a compost sifter, you should come up with a budget that will guide you in terms of how much you can spend, depending on the scale of the operation. It's important to remember that pricey doesn't always equal to the best quality, and you should instead rely on actual customer feedback and reviews to pick out the best compost sifter to buy at each price point.
4. Scale Of Operation
The scale of your composting operation will dictate the type of compost sifter you will need to buy. While dealing with large-scale compost piles, it's more convenient to get a motorized compost sifter that can automatically turn the drum and sift out the compost without much labor. On the other hand, small scale composting operations will most likely require a DIY compost sifter or a small-sized commercially built sifter.
