How is humus formed?
The best way to understand humus is to understand how it is formed. Dead plant and animal material consists of organic matter. Organic matter is a catch all phrase used to describe a wide range of molecules including starches, proteins, sugars, carbohydrates, amino acids etc. When organic matter starts to decompose these molecules are broken down into smaller and smaller molecules by the micro-organisms in the soil (mostly bacteria and fungi). This is a complex process and the gardener does not need to understand the details of the process. What is important is that most of the useable chemicals in the organic matter are extracted by the micro-organisms and are eventually made available to plants.

What is the charge of humus?
Humus has a negative charge which means that many of the nutrients plants require stick to humus, including ammonium (source of nitrogen), calcium, magnesium and phosphorous to name a few. The humus sponge holds onto these nutrients and prevents rain from washing them away. When a plant root comes in contact with it, the plant root is able to remove the nutrients from the humus sponge. The process is a bit more complicated than this, but you can think of humus as being a slow release source of fertilizer for your plants.

What is the function of humus?
One of the most important functions of humus is that it makes the soil more porous, improving soil aeration, infiltration and drainage . Humusless soil can become extremely compacted and airless and form very hard crusts that resist the infiltration of air, rain, or irrigation water and hence also prevent the emergence of seedlings. This function of humus improves the structure of the soil and in conjunction with humus’s capacity to retain important nutrients, humus rich soil helps plant grow more easily.

What is the process of humification?
Humification: Any organic substances that remain will then go through a process called "humification," in which fungi, bacteria, microorganisms, earthworms, and arthropods break the decaying matter down even further, resulting in polymers that exist as stable, permanent enhancers of the soil, or humic substances.

Composting attempts to repurpose yard waste such as grass cuttings and household waste such as coffee grounds, vegetable peels and cores, old bread, and newspaper. If a material is deemed compostable, it’s added to the compost mound and mixed in with the exiting material so that active microorganisms and air are spread throughout the pile. Decomposition occurs faster when the compost is mixed often. In addition to plant nutrients, composting allows concentrated growth of beneficial organisms, including bacteria and fungi, as well as ground dwelling insects and earthworms.
