Soil of Tropical Rainforest

The soil found in the tropical rainforest is very nutrient poor. This is due to the many decomposers and plants in need of any nutrients available, so they don't stay in the soil for long. The rain has left it acidic and lacking in minerals. The topsoil is very thin at only 1 to 2 inches deep. There are high concentrations of metals in the soil, creating mineral deposits.
