Marsandi F, Hermansah, Agustian, Yasin S. 2017. Review: Diversity of soil organisms and their relationship with diversity of plant species in tropical rainforest of Pinang-Pinang Padang, Indonesia. Pros Sem Nas Masy Biodiv Indon 3: 309-318. Tropical rain forests are the Earth's richest biological community as holder of an important role in maintaining the proportion of global biodiversity. These forests provide many ecosystem services in order fulfillment of human well-being. Land as a tropical rain forest floor also has an important role in maintaining ecological sustainability in the forest, where many living creatures that have direct or indirect dependency on the ground. This causes the soil is a medium that can provide nutrients for living things in it. The tropical rain forest of PinanangPinang (Padang, West Sumatra, Indonesia) has high diversity of tree and varied so that it becomes an attraction for scientists to conduct research. Researchers have grouped of Pinang-Pinang plots into three categories according to the degree of diversity of tree species, namely the high diversity, middle diversity and low diversity. The results of previous research on the plot state that Pinang-Pinang plot with a high degree of diversity of trees has the infertile soil and vice versa. Such phenomena are affected by plant group hyperaccumulator. So as to ensure the necessary study of soil organisms (microbes and soil fauna) as well as its relation to the diversity of species of tropical rainforest tree at Pinang-Pinang plot, West Sumatra, Indonesia.
