Understanding how to manage N inputs to identify the practices that maximize N recovery
has been an organizing principle of agronomic research. Because growth in N fertilizer …

Farmed soils contribute substantially to global warming by emitting N2O (ref.), and mitigation
has proved difficult. Several microbial nitrogen transformations produce N2O, but the only …

Nitrogen cycling in agroecosystems is heavily dependent upon arbuscular mycorrhizal fungi
(AMF) present in the soil microbiome. These fungi develop obligate symbioses with various …

Core Ideas Systematic review and meta‐analysis demonstrate key factors for reducing
agricultural N losses. Nitrification inhibitors and side‐dress fertilizer N each reduce N2O …

Abstract The Yaqui Valley, one of Mexico's major breadbaskets, includes∼ 230,000 ha of
cultivated, irrigated cropland, with two thirds of the area planted annually to spring wheat …
