MANGANESE: AN UNEXPLORED BOTTLENECK OF SOIL ORGANIC CARBON AND NITROGEN CYCLING IN AGROECOSYSTEMS

Objective

Determine the effect of Mn bioavailability on plant Mn uptake and residue decompositionEvaluate if Mn bioavailability imparts a measurable control on soil health-building soil properties and processesTask 1: Examine how a gradient of Mn bioavailability affects soil physical environment and soil organic C and N mineralization Task 2: Examine how a gradient of Mn bioavailability affects soil organic C stabilization Determine if combined Mn and N enrichment affects C and N cycling differently than Mn enrichment aloneDetermine the influence of Mn bioavailability to soil bacterial and fungal community composition and N cycling gene expression
