TL;DR: It is shown that limited phosphorus and nitrogen availability are likely to jointly reduce future carbon storage by natural ecosystems during this century and if phosphorus fertilizers cannot be made increasingly accessible, the crop yields projections of the Millennium Ecosystem Assessment imply an increase of the nutrient deficit in developing regions.

Abstract: Bioavailable nitrogen is increasing due to human activity, rapidly outpacing increases in another essential nutrient, phosphorous. Penuelas et al. show that this increasing imbalance between these nutrients is likely to significantly affect life and limit carbon storage in this century.

Soil Acidification in Nutrient-Enriched Soils Reduces the Growth, Nutrient Concentrations, and Nitrogen-Use Efficiencies of Vachellia sieberiana (DC.) Kyal. & Boatwr Saplings
TL;DR: In this paper , the authors investigated how soil enriched with N and P influenced soil concentration correlations and affected the growth kinetics, mineral nutrition, and nitrogen-use efficiencies of Vachellia sieberiana grown in a greenhouse experiment.
Long-term nitrogen enrichment does not increase microbial phosphorus mobilization in a northern coniferous forest
TL;DR: In this paper, the authors studied microbial phosphorus mobilization and growth within a long-term N enrichment experiment in a Norway spruce forest, where N deposition was simulated by adding 0, 12.5 or 50 kg N ha−1 year−1 for 21 years (n = 12).

Changes in soil enzymatic activity in a P-limited Mediterranean shrubland subject to experimental nitrogen deposition
TL;DR: In this article, seasonal effects of N deposition on the activities of five soil extracellular enzymes in a semi-arid, P-deficient Mediterranean shrubland, and the association with physical and nutritional soil variables were studied.

Shoot and root biomass production in semi-arid shrublands exposed to long-term experimental N input
TL;DR: It is indicated that long-term N inputs will lead to complex, spatially and temporally variable growth responses for these, and similar, Mediterranean-type shrublands.

Nitrogen use efficiency of terrestrial plants in China: geographic patterns, evolution, and determinants
TL;DR: Zhang et al. as mentioned in this paper analyzed the geographic patterns of NUE and explored its phylogenic and environmental drivers across 1452 species at 1102 sites in China and found that NUE tended to decrease with latitude (r = − ǫ 0.56), whereas it increased with longitude (r͡= 0.54), and varied widely in different ecosystems and plant life forms.

TL;DR: It is shown that tremendous progress could be made by halting agricultural expansion, closing ‘yield gaps’ on underperforming lands, increasing cropping efficiency, shifting diets and reducing waste, which could double food production while greatly reducing the environmental impacts of agriculture.

TL;DR: In this paper, the authors compared the natural and anthropogenic controls on the conversion of unreactive N2 to more reactive forms of nitrogen (Nr) and found that human activities increasingly dominate the N budget at the global and at most regional scales, and the terrestrial and open ocean N budgets are essentially dis-connected.

TL;DR: A large-scale meta-analysis of experimental enrichments shows that P limitation is equally strong across these major habitats and that N and P limitation are equivalent within both terrestrial and freshwater systems.
