Where are the most nutrients stored in a tropical rainforest before deforestation?

In a tropical rainforest, the majority of nutrients are stored in the biomass of the vegetation, particularly in the trees and their leaves. The rich organic matter in the soil also contributes to nutrient storage, though it is less than that found in the living plants. When deforestation occurs, the loss of this biomass leads to a significant decline in nutrient availability, disrupting the entire ecosystem.
