On the cover: Pots housed within individual containers designed to maintain microarthropod treatments while allowing air flow and light for the oats. To see how this experiment was used to explore the interactive effects of microarthropods and fertilizers on crop productivity, see the article "Microarthropods improve oat nutritional quality and mediate fertilizer effects on soil biological activity" by Jernigan et al. in this issue of the journal.
