The heavy rain leaches nutrients from the topsoil. crops can be grown year round because of the warm soil temperature, so plants are using nutrients from the soil year-round.

The answer is for a fact Tropical Rain Forest

Soils are often affected by the raindrops. When rainfall occurs, the raindrops strike the surface of the soil, as a result of which the topsoil is removed, thereby carrying away the necessary nutrients along with it.

In the tropical rainforest, the rainfall is the maximum because of the increasing temperature condition. It is because this region is the near-equatorial region. As a result of which the soils are affected.

But the soil temperature also plays an important role in the growth of plants. The temperature of the soil affects the growth of plants indirectly by affecting moisture content in the soil and up-taking of nutrients and growth of roots. Generally, increasing temperature results in increased moisture content and nutrient uptake. At a comparatively lower temperature, the transportation of nutrients from the root to the shoot and vice versa normally reduces.

Thus, in spite of heavy rainfall in the tropical rainforest region, there occurs numerous amount of tree species, which is usually facilitated by the soil.
