What’s it all mean? Lots of factors controls MAOM formation! That different factors control C & N stabilization to minerals - microbial synthesis for N; direct sorption for C – also means that efforts to increase soil C storage may not necessarily increase N retention.

We found 1) most variation in MAOM related to FeOx (60-68%), 2) bacterial diversity contributes to MAOM when low (but not high) melanin necromass is present, 3) low melanin forms MAOM more readily than high melanin necromass, & 4) necromass N forms 7x more MAOM than necromass C

We added 15N and 13C labeled necromass (high and low melanin) to soils with diff. mineralogies & microbial communities in a jar incubation. The soils were sourced from across southern Indiana and had iron oxide contents that differed by two orders of magnitude.

Exciting new work from the amazin’ @BeidlerKatilyn & @UMNFuN. Much of the OM that “sticks” to minerals comes from dead fungi. But what controls formation rates: input chemistry, mineral reactivity or microbes involved in hyphal decay?

So? N resorption has consequences for plant economics & litter-soil-nutrient feedbacks. Given that root foraging is not the only way to acquire soil N, detecting AG-BG trait linkages in forests may require accounting for myco symbionts, tree neighborhoods and site fertility.

Trees in the garden that resorbed more N produced more roots indicating resorption patterns can cascade to affect litter qual & N availability. In mature stands, we couldn't detect resorption-root relationships despite a strong neg relationship btwn resorption and litter quality.

This took a minute but excited to share it now Trees get N by resorbing from foliage & foraging in soil - but are the two coordinated? We tested hypotheses abt relationships btwn resorption & root production for 12 spp in mature forests & 9 spp in a garden.
