- The soil is poor in nutrients and acidic due to frequent leaching by heavy rains.
- Frequent rains wash away the top soil leaving only certain mineral and organic remains. So, if these forests are cleared, it will not yield tremendous vegetation growth as seen in tropical forests for a long time.
- However, rainforests are also notable for replenishing the soil quickly with dead organic matter (e.g. leafs that fall from trees).

Intense leaching of soil in tropical rain forests:
- Tropical rain forests receive high amounts of rainfall throughout the year, leading to intense leaching of nutrients from the soil.
- The constant rainfall washes away essential nutrients like nitrogen, phosphorus, and potassium, making them unavailable for plant uptake.
- This nutrient depletion results in lower primary productivity as plants struggle to obtain the necessary nutrients for growth and development.
Low microbial activity in tropical regions:
- Tropical regions often have high temperatures and moisture levels, which can inhibit microbial activity in the soil.
- Microbes play a crucial role in nutrient cycling and decomposition processes, which are essential for plant growth and productivity.
- The lower microbial activity in tropical rain forests can result in slower nutrient recycling and availability for plants, contributing to decreased primary productivity.
Therefore, the primary productivity of tropical rain forests is lower compared to temperate forests due to a combination of intense leaching of soil nutrients and low microbial activity in tropical regions.
