“…Most literature on plant nutrient uptake and use considers only few nutrient elements, mainly N and sometimes also P, although also other nutrients are important in co-limiting plant growth (Agren 1988;Reich et al 2014). The nature of nutrient limitation has been previously explored with variable success by using critical nutrient ratios (Drenovsky and Richards 2004;Koerselman and Meuleman 1996), but also those approaches are usually restricted to the consideration of only few nutrients that usually were assessed only at single points in time.…”

“…Data source and detailed information about the growth conditions: Hamner et al (2017) rate (Knecht and Goransson 2004). The exact formulation of growth co-limitation by different nutrients appears to be species-specific (Agren 1988) and is a neglected research area (Reich et al 2014). Future studies should include experiments in which plants grown at different growth rates are limited by several nutrients simultaneously and monitored throughout their entire growth cycles.…”

“…In general, nutrient use efficiency often considers the processes of carbon gain and loss in relation to the processes associated with the gain and loss of the major growth-limiting nutrients (Reich et al 2014;Weih et al 2017), and is often defined as mass balance between either the plant-internal or soil available nutrient amount, and the biomass output (e.g. whole-plant net biomass accumulation or harvested biomass yield).…”

“…The terms nutrient use efficiency and nitrogen use efficiency, with the frequently used acronym NUE, have been used with reference to the properties of either individual plants or production systems with respect to the use of nutrients or N (Fageria and Baligar 2005;Reich et al 2014;van Bueren et al 2014). According to these and many other authors, there is no commonly agreed definition of NUE and, depending on the scale or target of the research, NUE refers to different identities.…”

Analyzing plant nutrient uptake and utilization efficiencies: comparison between crops and approaches

Background Various indices are applied to evaluate the nutrient (mostly nitrogen, N) use efficiency of plants, but those indices have rarely been compared across different crops, and the co-limitation of growth by nutrients other than N is usually not considered. Aims To conceptually and quantitatively compare the indices of a plant-level, a plant-soil-level and a fieldlevel (difference) method for the assessment of N use across a set of different annual and perennial crops; and to use some plant-level indices for exploring the colimitation of growth by nutrients other than N in wheat. Method Data sets from previously published studies on wheat (grain), maize (feed), potato (starch), grassland ley (feed) and Salix (bio-energy) field-grown in Sweden were re-analyzed. Conclusions This study is first in conceptually and quantitatively comparing various popular N use indices across a wide range of annual and perennial crops; and also proposes a methodology for exploring the colimitation of growth by nutrients other than N. When comparing the plant-level and plant-soil-level methods, the indices relating crop yields to the amounts of plantinternal N were correlated, while the N-uptake indices were not. Only few of the field-level (differencemethod) indices were correlated with indices of the two other methods.

“…Understanding interactions between plant nutrients is essential for optimizing fertilization strategies and improving nutrient use efficiency in crops (Baxter, 2009 ; Maathuis, 2009 ; Reich et al, 2014a ). Sulfur was recognized as an essential nutrient for crops more than a century ago (Bogdanov, 1899 ; Hart and Peterson, 1911 ) and since then it had shown to be involved in many vital processes in plants (Thompson, 1967 ; Hell, 1997 ; De Kok et al, 2005 ; Hawkesford and De Kok, 2006 ; Takahashi et al, 2011 ).…”

Interactions of Sulfate with Other Nutrients As Revealed by H2S Fumigation of Chinese Cabbage

Sulfur deficiency in plants has severe impacts on both growth and nutrient composition. Fumigation with sub-lethal concentrations of H2S facilitates the supply of reduced sulfur via the leaves while sulfate is depleted from the roots. This restores growth while sulfate levels in the plant tissue remain low. In the present study this system was used to reveal interactions of sulfur with other nutrients in the plant and to ascertain whether these changes are due to the absence or presence of sulfate or rather to changes in growth and organic sulfur. There was a complex reaction of the mineral composition to sulfur deficiency, however, the changes in content of many nutrients were prevented by H2S fumigation. Under sulfur deficiency these nutrients accumulated on a fresh weight basis but were diluted on a dry weight basis, presumably due to a higher dry matter content. The pattern differed, however, between leaves and roots which led to changes in shoot to root partitioning. Only the potassium, molybdenum and zinc contents were strongly linked to the sulfate supply. Potassium was the only nutrient amongst those measured which showed a positive correlation with sulfur content in shoots, highlighting a role as a counter cation for sulfate during xylem loading and vacuolar storage in leaves. This was supported by an accumulation of potassium in roots of the sulfur-deprived plants. Molybdenum and zinc increased substantially under sulfur deficiency, which was only partly prevented by H2S fumigation. While the causes of increased molybdenum under sulfur deficiency have been previously studied, the relation between sulfate and zinc uptake needs further clarification.
