Tropical Rain Forest Soils of La Selva

The soil of the rainforest in La Selva Worldwide tropical rainforests are now threatened by widespread deforestation, grazing and agriculture (Otzen 1993). This land use pattern changed the temperature condition like temperature, soil, surface water, flora, fauna and microorganisms (Fernandes and Sanford 1995). These changes are due to a decrease in soil organic matter, a decrease in soil fertility (Garcia-Oliva et al. 1994, Tissen et al 1994), intense soil erosion (Otzen 1993), and soil structure and chemistry changes (Fernandes) and Sanford It may lead to 1995. , Sorin etc.

Soil erosion due to overuse of meadow and subsequent population pressure, desertification, logging of tropical rainforest to respond to international demand of tropical timber, domestic use as fuel, loss of biodiversity Fertilization of dam Supply of inappropriate drinking water: Because the national estimate clearly takes into account the high mortality rate by AIDS, it is important to reduce average life expectancy, increase infant mortality rate, increase mortality rate, and decrease population growth rate There is a possibility of connecting. Changes in population distribution by age and sex (estimated in July 2017)

This is a phenomenon in which forest soil is peeled off by erosion and weathering. It is well known that tropical rainforests are the most diverse terrestrial ecosystem on Earth. However, it occupies less than 10% of the surface of the earth, and they contain more than half of the creatures recorded worldwide. The Philippine economy and ecology depend heavily on this rich ecosystem. Forests provide renewable foods, textiles, chemicals, wood, and other wood products that animate our economy. They also provide many ecological functions to help protect soil and water; supplement oxygen supply and reduce air carbon dioxide

Decomposition in the rainforest is rapid due to high temperature and abundant humidity. Tropical soil is subject to extreme chemical weathering and leaching due to frequent and intense rainfall. These environmental conditions make the tropical soil acid and malnourish. Tropical and subtropical dry hardwood forest Tropical and subtropical dry forests (also known as seasonal tropical forests or tropical dry forests) are distributed in eastern Bolivia, New Caledonia, New Caledonia, southern India, southern India, southeast Africa It is. , Central Brazil, the Caribbean Sea, and the coasts of Peru and Ecuador
