Humus is not Humus 12. Humus is a dark, organic material that forms in soil when plant and animal matter decays. It's essentially partially decomposed organic matter and a vital component of healthy soil. It's impossible to quantify it with a number like "12".
Here's a more detailed breakdown:
Humus Explained
-
Formation: Humus is created through the decomposition of organic materials such as dead leaves, plants, and animal waste. This process is carried out by microorganisms in the soil.
-
Appearance: It's usually dark brown or black in color due to the complex organic compounds it contains.
-
Benefits for Soil:
- Nutrient Retention: Humus acts like a sponge, holding onto essential nutrients that plants need to grow.
- Water Retention: It improves the soil's ability to retain water, making it more drought-resistant.
- Soil Structure: Humus helps to create a porous soil structure, improving aeration and drainage. This allows roots to grow more easily and prevents waterlogging.
- Microbial Activity: It provides a food source for beneficial microorganisms in the soil, which further enhances soil health.
- Increases Soil Fertility: By improving soil structure, water retention, and nutrient availability, humus significantly contributes to soil fertility, promoting healthy plant growth.
-
How it Differs From Compost: While both humus and compost are beneficial for soil, they're not the same thing. Compost is actively decomposing organic matter, while humus is the stable, final product of decomposition. Think of humus as the end result of well-aged compost in the soil.
In short, humus is not something you can assign a numerical value to. It's a substance that benefits the soil greatly.
