The warm, damp conditions on the forest floor and the abundance of insects enables the rapid breakdown of dead leaves and plant material. This humus provides nutrients that are easily absorbed by plant roots. Because of the abundance of rainforest vegetation, nutrients are used up quickly.
In this context, humus refers to the organic matter that is formed by the decomposition of dead leaves, plant material, and other organic substances on the forest floor. It is a dark, nutrient-rich material that provides essential nutrients to plant roots for their growth and development.
