Tropical soil health measures

On November 28 Kristina Estrada and Tanner Beckstrom presented on their ongoing research into soil health measures. Estrada is looking at plant biodiversity and Beckstrom is studying the soil. Their work specifically focuses on tropical oxisol soils and their ability to support biodiversity.

Soil provides a critical ecosystem service for plants. Beckstrom covered soil health which includes physical, biological, and chemical constituents. 


Beckstrom explains the function of soil.



Estrada is looking at the biodiversity supported by a given soil. The relationship between soil health and biodiversity is a central part of the research. 


The researchers are also looking at how specific farming practices contribute to overall soil health. The local approach to agroforestry, a mixed crop no till with mulching by leftover vegetative material after harvest all contribute to soil health.
