Impact Of Fertilizer, Corn Residue, And Cover Crops On Mycorrhizal Inoculum Potential And Arbuscular Mycorrhizal Fungi Associations, Rachel Brockamp
Impact Of Fertilizer, Corn Residue, And Cover Crops On Mycorrhizal Inoculum Potential And Arbuscular Mycorrhizal Fungi Associations, Rachel Brockamp
Undergraduate Research Symposium 2017
Arbuscular Mycorrhizal Fungi (AMF) can associate with roots of most land plants, helping to take up water and nutrients. Intensive agricultural practices like fallow treatments and adding inorganic nutrients reduce soil AMF. The purpose of my research was to examine whether three factors influenced AMF-crop associations: 1) fertilizer type and application rate 2) inclusion of cover crops that do or do not associate with AMF, and 3) impacts of corn residue. Soil Mycorrhizal Inoculum Potential (MIP) was measured to test treatment differences. MIP is the ability for soil AMF to infect roots. Roots grown in soil from the different treatments …
