Installing soil sensors is dirty work!

 

My research at the Menge Lab explores biogeochemistry and ecosystem ecology in agricultural systems. I’m interested in optimizing the use of nitrogen to maximize ecosystem services such as food production, nutrient cycling, and carbon storage, while minimizing the associated ecological and environmental costs of unwanted nutrient export such as eutrophication, greenhouse gas production, and biodiversity loss. 

Descent into the 10m soil pit!

     

My dissertation focuses on the following: 

How might reactive nitrogen losses differ in tropical regions where production is likely to increase compared to well-studied temperate croplands?

What management practices can reduce reactive nitrogen losses on existing intensified croplands?

I’m approaching these questions with a mix of field, laboratory, and meta-analysis techniques and have established field studies both in Cerrado/Amazon region of Brazil and a traditional temperate agricultural research station in Southern Sweden.
