2-ATLANTIC FOREST: BIOGEOCYCLING
Fallen parts of plants (tree trunks, leaves, branches, flowers, fruits...) and dead animals form the necromass on forest ground. We can observe 3 layers in this necromass: 1) Parts of plants not yet decomposed; 2) Partially decomposed; 3) Mostly decomposed and mixed with soil particles making up the humus. And under the necromass we find root mats. Root mats are typical of rain forests on extremely infertile soils like this oxisol of the Atlantic Forest. These roots absorb minerals that are leached out of the decomposing leaf litter or necromass. These plant roots are naturally infected with endomycorrhizal fungi which increase the absorption capacity of the roots. These root mats and organic matter in decomposition are concentrated on top 10 cm of the soil. Believe it or not! The soil richness of the Atlantic Forest is on the top 10 cm or so!!!

Cagaiteira Eugenia dysenterica DC The Cerrado is a tropical savanna types occupying approximately 2.0 million km2 and accounts for 23.1% of Brazilian territory. (BUSHBACHER, 2000). Although it is a poorly studied biome, it is known that constitutes one of the regions of greatest biodiversity. Some Cerrado plant species may be potential sources of economic exploitation, since the research and technologies enable its use. In this context, it fits the (Eugenia dysenterica DC.), A fruit species native to Savannah, seized by the local population for food and medicinal use. Cagaiteira The cagaiteira, also known as cagaita because of its laxative properties, is a fruit tree's natural Cerrado, belonging to the family Myrtaceae. According Naves (1999), occurs in greater density in the Oxisol was more frequent in areas with annual average temperatures ranging between 21 ° C and 25 ° C and altitudes from 380 to 1100 m. It constitutes a tree of medium size, possessing 40 to 10 m tall, trunk cylindrical and tortuous, with 20 to 40 cm in diameter and a suberosa bark and chipped very characteristic.
