Which nutrient store holds the majority of the nutrients in the Australian savanna?

In the Australian savanna, the majority of nutrients are stored in the soil. This unique ecosystem is characterized by a combination of grasses, scattered trees, and a seasonal climate. The soils in the savanna can vary but often have good nutrient availability directly tied to organic matter from decomposing plant material. However, these soils can also be relatively poor in certain nutrients due to factors such as leaching and limited moisture.

The nutrients in the Australian savanna are primarily found in the following:

1. Soil Organic Matter: Decomposed plant and animal materials contribute significantly to nutrient content, providing essential elements like nitrogen and phosphorus.
2. Root Systems: The extensive root networks of grasses and trees also play a vital role in nutrient uptake and storage within the soil.
3. Microbial Activity: Soil microorganisms contribute to nutrient cycling, breaking down organic materials and making nutrients available to plants.

Overall, while plant biomass stores some nutrients, the majority resides in the soil, highlighting the critical importance of soil health for sustaining the savanna ecosystem.
