Is humus and compost the same thing?
Humus is the end result of the decompositions process, whereas compost is a word that identifies a phase of the decomposition process where decomposing plant material provides the most benefit to the soil.

Compost is considered “finished” when we are left with the semblance of a rich, organic soil where our individual contributions are no longer distinguishable.
What is Humus Made of?
As the little critters continue their dinner party, they break things down on a molecular level, slowly releasing nutrients into the soil for plant uptake. Humus is what’s leftover at the conclusion of the dinner feast, which is when all the usable chemicals in the organic matter have been extracted by the microorganisms.
Why is Humus Important?
How is humus used in gardens and why is humus important? As I mentioned earlier, humus is spongy in nature. This is significant because this attribute enables humus to hold up to 90% of its weight in water, meaning soil laden in humus will be able to retain moisture better and be more drought resistant.

Example
- So basically, the finished compost we put in our gardens really only contains a very small percentage of humus. Compost literally takes years to fully decompose into a humus state. When the compost is fully decomposed it will then be 100% humus.
Story
- As the little critters continue their dinner party, they break things down on a molecular level, slowly releasing nutrients into the soil for plant uptake. Humus is whats left over at the conclusion of the dinner feast, which is when all the usable chemicals in the organic matter have been extracted by the microorganisms.
Formation
- Humus is essentially a dark, organic, mostly carbon-based spongy substance in the soil that has a shelf life of hundreds of years or more. So to recap the whole compost vs. humus debacle, while humus can be created through the composting process (albeit very, very slowly), compost is not humus until it is decomposed down to dark organic material th...
Cultivation
- How is humus used in gardens and why is humus important? As I mentioned earlier, humus is spongy in nature. This is significant because this attribute enables humus to hold up to 90% of its weight in water, meaning soil laden in humus will be able to retain moisture better and be more drought resistant.
Ecology
- The humus sponge also latches onto and safeguards nutrients that plants require, such as calcium, magnesium and phosphorus. Plants can siphon these much needed nutrients from the humus through their roots.
Benefits
- Humus gives soil a much desired crumbly texture and improves soil structure by making the soil looser, allowing for easier flow of air and water. These are just a few great reasons on why humus is important to your garden.
