Goals / Objectives
1.) To improve understanding of management impacts on community structure and function soil microorganisms in highly productive crop systems; 2.) Quantify the role of soil microorganisms in the acquisition and uptake of nutrients and water; and 3.) Determine how soil microorganisms influence or regulate plant nutrient transporter mechanisms.

Project Methods
Microbial communities will be evaluated using FAME analysis. Nutrient transformation and plant transporter mechanisms will be evaluated using molecular methods. Plant â¿¿ microbe interactions affecting nutrient and water acquisition will be evaluated by quantifying enzyme activity.
