I feel that the trip was particularly successful. In my own research I have found that diverse communities of arbuscular mycorrhizal fungi (AMF) actually survive in the cotton cropping soils at Narrabri. Before I started my PhD it was generally considered that AMF are sensitive to agricultural practices and that diversity is low in these systems. In Spain I met with several people who have also found high AMF diversity in cropped soils. This was very exciting. I also had many queries about the AMF PCR primers I developed during the project.
