Title:	Data from NEGATIVE EFFECTS OF NITROGEN OVERRIDE POSITIVE EFFECTS OF PHOSPHORUS ON GRASSLAND LEGUMES WORLDWIDE
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	Anthropogenic nutrient enrichment is driving global biodiversity decline and modifying ecosystem functions. Theory suggests that plant functional types that fix atmospheric nitrogen have a competitive advantage in nitrogen-poor soils, but lose this advantage with increasing nitrogen supply. By contrast, addition of phosphorus, potassium and other nutrients may benefit such species in low nutrient environments by enhancing their nitrogen-fixing capacity. We present the first global-scale experiment confirming these predictions for nitrogen-fixing legumes (Fabaceae) across 45 grasslands on six continents. Nitrogen addition reduced legume cover, richness, and biomass particularly in nitrogen-poor soils while cover of non-nitrogen-fixing plants increased. Addition of phosphorous, potassium, and other nutrients enhanced legume abundance but did not mitigate the negative effects of nitrogen addition. Increasing nitrogen-supply thus has potential to decrease the diversity and abundance of grassland legumes worldwide regardless of the availability of other nutrients, with consequences for biodiversity, food webs, ecosystem resilience and genetic improvement of protein-rich agricultural plant species.

Methods and protocols used in the collection of this data package

Description:

These methods, instrumentation and/or protocols apply to all data in this dataset. Experimental design and treatments are detailed in www.nutnet.org

Sites.

Sites included 45 natural and anthropogenic grasslands from six continents, most in temperate climate zones. We included all Nutrient Network sites with N-fixing legumes in their regional composition and that had applied nutrient treatments for at least 3 years (see below).

Treatments.

Each site established eight 5 x 5 m plots per block to accommodate a single replicate of eight treatments per block, with sites mostly containing 3 blocks. All sites had the same treatments, involving factorial combinations of nitrogen, phosphorus and potassium addition and an untreated control. Nutrients were added annually as follows: 10 g N m-2 yr-1 as timed-release urea ((NH2)2CO), 10 g P m-2 yr-1 as triple-super phosphate (Ca(H2PO4)2), 10 g K m-2 yr-1 as potassium sulphate (K2SO4). Plots receiving potassium also received a once-off addition of other macro- and micronutrients in the first year: 100 g m-2 of a mix containing Fe (15%), S (14%), Mg (1.5%), Mn (2.5%), Cu (1%), Zn (1%), B (0.2%) and Mo (0.05%).

Vegetation sampling.

Plant cover and biomass were measured annually, beginning one year before treatments were applied. Within each treatment plot, the cover of each vascular plant species was estimated to the nearest 1% in a permanent 1 x 1 m subplot during the season of peak biomass at each location. Sites with two biomass peaks were measured at each peak, and data averaged between sampling dates in each year. For each plot in each year, we calculated the cumulative cover for species belonging to four key functional groups: N-fixing legumes, other forbs, graminoids (grasses + sedges). Adjacent to the 1 x 1 m cover subplot, all aboveground biomass was clipped in two 1 x 0.1 m strips (0.2 m2), dried at 60°C and weighed to the nearest 0.01 g. Biomass was sorted to the functional group level in 30 of the 45 sites. A range of plant community-level variables were calculated from the plant cover data for the third or last year of the experiment in each plot (plot-level predictors) or across all plots (site-level predictors). The latter were measured either at the beginning of the experiment or averaged across all plots in a site. At the plot level, we considered initial legume cover (%) and legume richness (number of species), initial total non-native cover (%), initial live biomass (g m-2) and third or last year abundance of grasses and forbs (%). At the site level, we calculated initial mean legume cover (%), legume richness (number of species), total live plant biomass (g m-2), mean native and non-native plant cover (%).

Photosynthetically active radiation (PAR, µmol photons m-2 s-1) was measured annually in the 1 m2 cover-sampling subplots, in cloud-free conditions between 10am and 2pm during peak biomass. One above-canopy and two perpendicular ground level measurements were made in each plot using a 1-m light ceptometer. Proportion of PAR was calculated as the ratio of the average ground level and the incident above-canopy PAR readings.

Soils.

Soil chemical properties at the plot level at the beginning of the experiment were measured in 37 of the 45 sites. In each plot, two 2.5 cm diameter x 10 cm depth soil cores, free of litter and vegetation, were collected, combined, homogenized, air-dried and shipped to a single laboratory (A&L Laboratories, Memphis, Tennessee, USA) for analysis using standard methods. In particular, we measured soil pH, N:P ratio, total N (%), extractable P (ppm), extractable K (ppm), Calcium (Ca, ppm), Magnesium (Mg, ppm), Sulfur (S, ppm), Sodium (Na, ppm), Manganese (Mn, ppm), Iron (Fe, ppm), Copper (Cu, ppm), and Boron (B, ppm).

Climate.

Mean annual precipitation (MAP, mm), mean annual temperature (MAT, °C), and aridity index (AI) were derived from https://www.worldclim.org/

Abstract:

Two of the most pervasive human impacts on ecosystems are alteration of global nutrient budgets and changes in the abundance and identity of consumers. Fossil fuel combustion and agricultural fertilization have doubled and quintupled, respectively, global pools of nitrogen and phosphorus relative to pre-industrial levels. Concurrently, habitat loss and degradation and selective hunting and fishing disproportionately remove consumers from food webs. At the same time, humans are adding consumers to food webs for endpoints such as conservation, recreation, and agriculture, as well as accidental introductions of invasive consumer species. In spite of the global impacts of these human activities, there have been no globally coordinated experiments to quantify the general impacts on ecological systems. The Nutrient Network (NutNet) is a grassroots research effort to address these questions within a coordinated research network comprised of more than 130 grassland sites worldwide.

NutNet focal research questions:

How general is our current understanding of productivity-diversity relationships?

To what extent are plant production and diversity co-limited by multiple nutrients in herbaceous-dominated communities?

Under what conditions do grazers or fertilization control plant biomass, diversity, and composition?
