Input-output estimates of nitrogen (N) on cropland are essential for improving N management and better understanding the global N cycle. Here, we compare 13 N budget datasets covering 115 countries and regions over 1961-2015. Though most datasets showed similar spatiotemporal patterns, some annual estimates varied widely among them, resulting in large ranges and uncertainty. In 2010, global medians (in Tg N yr-1) and associated min-max ranges were 73 (64-84) for global harvested crop N; 161...

Quantitative assessment of agricultural sustainability reveals divergent priorities among nations

Agriculture is fundamental to all three pillars of sustainability, environment, society, and economy. However, the definition of sustainable agriculture and capacities to measure it remain elusive. Independent and transparent measurements of national sustainability are needed to gauge progress, encourage accountability, and inform policy. Here, we developed a Sustainable Agriculture Matrix (SAM) to quantify national performance indicators in agriculture and to investigate the tradeoffs and synergies based on historical data for most countries of the world....

Tree water uptake enhances nitrogen acquisition in a fertilized boreal forest – but not under nitrogen poor conditions

Nils Henriksson, Hyungwoo Lim, John Marchall, Oskar Franklin, Ross McMurtrie, Reimo Lutter, Ruth Magh, Tomas Lundmark & Torgny Näsholm
Understanding how plant water uptake interacts with acquisition of soil nitrogen (N) and other nutrients is fundamental for predicting plant responses to a changing environment, but it is an area where models disagree. We present a novel isotopic labelling approach which reveals spatial patterns of water and N uptake, and their interaction, by trees. The stable isotopes 15N and 2H were applied to a small area of the forest floor in stands with high and...
