Importance of Humus
- Describe and define the term: humus. Why would you think hummus is important for agriculture?
Humus is a dark, organic substance formed through the decomposition of plant and animal matter in soil. It is rich in nutrients and serves several critical functions in agriculture:
- Nutrient Retention: Humus has a high cation exchange capacity, meaning it can attract and hold onto positively charged ions like calcium, magnesium, and potassium. This helps to retain nutrients in the soil and makes them more available for plant uptake, contributing to soil fertility.
- Soil Structure: Humus improves soil structure by binding soil particles together into aggregates. This creates pore spaces that enhance soil aeration and water infiltration, promoting root growth and providing a favorable environment for soil organisms.
- Water Retention: The porous structure of humus allows it to hold water like a sponge. This improves the soil’s water-holding capacity, reducing the risk of waterlogging or drought stress for plants and supporting more stable soil moisture levels.
- Microbial Activity: Humus provides a habitat and energy source for soil microorganisms, such as bacteria and fungi. These microorganisms play vital roles in nutrient cycling, organic matter decomposition, and the suppression of soil-borne diseases…
