Humus is a dark, organic material that forms in the soil as a result of the decomposition of plant and animal matter. It is made up of complex compounds such as lignin, cellulose, and proteins.
Humus is important for plants and animals because it provides several benefits:
Nutrients: Humus is rich in nutrients such as nitrogen, phosphorus, and potassium, which are essential for plant growth.
Water retention: Humus helps to hold water in the soil, making it available to plants even during dry periods.
Soil structure: Humus improves the structure of the soil, making it more porous and easier for roots to penetrate.
Soil fertility: Humus helps to improve the fertility of the soil, making it more productive and better able to support plant growth.
Soil microorganisms: Humus is home to microorganisms that play a role in breaking down organic matter, and recycling nutrients back into the soil.
Soils that are low in humus content are typically sandy soils or soils with a high clay content that are not well aerated. Humus is not easily formed in these types of soil, and thus, the soil is not able to retain water and nutrients as effectively.
It's worth mentioning that humus is not only important for plants and animals but also for the overall environment as it helps to maintain soil health, which in turn supports the biodiversity of the ecosystem.
