- Abstract
Micronutrients are very important in the maintenance of soil fertility, and their deposition through litter in the Atlantic Forest is still little studied. This study aimed to evaluate the concentration and input of micronutrients by litterfall in secondary areas of Submontane Atlantic Rain Forest in Antonina, PR. The litter was collected in three plots at different stages of secondary succession, separated into fractions and leaves of selected species, dried and weighed to perform the chemical analysis of Cu, Mn, Fe and Zn. The concentration order of the micronutrients was Mn > Fe > Cu > Zn, with relatively high Mn and Fe contents. Among of litter fractions, there was a great variation in the micronutrient contents, where the concentration of Cu was higher in the branches and miscellaneous, the Fe content was higher in the leaves and in the miscellaneous, the Mn was superior in the branches and the Zn was higher in the branches and leaves. There was a great variation in the contents of the seasons of the year, with no defined trend. Cu and Fe contents were lower in FS-2, while Zn showed no particular trend. Mn content increased with forest sucession suggesting bioaccumulation of Mn in the forest soil.
