Nitrogen Fixation

Need nitrogen fixing bacteria in places such as panama have begun to decline in their productivity and even existence for as deforestation begins to become more rampant in places such as Panama, the amount of bacteria that is coexisting with the vast root systems of trees native to the regions are beginning to decrease. Without the needed root nitrogen being dissolved the soil will become less furtle  and may become to infertile to support the needs of local vegetation that relies heavily on such abiotic factors.
