Juan Almeida
I am a post doc researcher working on soil ecology, soil microbial interactions and nutrient cycling in perennial cropping systems.

Presentation

I have experience in the fields of plant and fungal physiology, plant-soil-microbial interactions, soil ecology, biogeochemical cycles and nutrient limitation in forested and agricultural ecosystems.  In agricultural systems I have studied the capability of perennial and mixed crops to desorb phosphorus tingly bound on mineral surfaces.

Currently, I am working on a project aiming to understand the effect of the perennial intermediate wheatgrass (Kernza®) on soil fertility and microbial activity. Our objective is to elucidate the soil ecosystem services of sustainable agricultural practices and cropping systems diversification
