Actual soil fertility is the amount of nutrients and moisture derived from the soil by the plants in a given year.
Soil fertility in tropical rainforest soils is low. This is because of the warm climate and the availability of water, both of which increase microbial activity, chemical reaction times, and the leaching of soluble soil constituents.lant nutrients are often locked up as part of soil minerals and soil organic matter. The rainforest environment decomposes these more complex, insoluble substances, and the rapidly growing plants of the rainforest take these nutrients up.
