“…These findings support the analysis produced in published simulation experiments Monjardino et al, 2013). It is clear that the sandy soil types were more limited for N supply than for P. There were however instances of a wheat yield response to P, but these were not found to consistently influence NUE and apparent N recovery in contrast with the recent analysis of experiments by Duncan et al (2018). The yield responses to P were measured despite soil test P values in excess of critical values, and the timing of P response was not clearly linked to a temporal effect supporting the findings of Lambert et al (2006).…”

“…Nitrogen (N) is known to be a leading cause of wheat yield gaps in Australian cropping systems (Hochman & Horan, 2018), and Cui et al (2014) argue that closing the gap between actual and attainable N use efficiency (NUE) is an important target in the goal of closing yield gaps. Further to this, a recent review of Duncan, O'Sullivan, Roper, Biggs, and Peoples (2018) finds that the key to increasing NUE potentially lies with co-application of other macronutrients, in particular phosphorus (P). Because of the water-driven riskiness of crop production in low rainfall environments, inputs of organic matter and fertiliser nutrients both tend to be low (Sadras, 2002).…”

“…It is often assumed that there will be a positive synergy for grain yield and NUE when N and P are applied together in low fertility situations, and this synergy has been demonstrated several times in Australian cropping systems (Alston, 1980;Armstrong, Millar, Halpin, Reid, & Standley, 2003;Brennan & Bolland, 2009;Colwell, 1963a;Duncan et al, 2018;Holford, Doyle, & Leckie, 1992;Officer, Dunbabin, Armstrong, & Norton, 2008). Brennan and Bolland (2009) measured an increased demand for N with increasing levels of P input at seven sites across three seasons for both wheat and canola grown on sands in Western Australia.…”

A primary driver of the wheat yield gap in Australia and globally is the supply of nitrogen (N) and options to increase N use efficiency (NUE) are fundamental to closure of the yield gap. Co-application of N with phosphorus (P) is suggested as an avenue to increase fertiliser NUE, and inputs of N and P fertiliser are key variable costs in low rainfall cereal crops. Within field variability in the response to nutrients due to soil and season offers a further opportunity to refine inputs for increased efficiency.The response of wheat to N fertiliser input (0, 10, 20, 40 and 80 kg N ha -1 ) under four levels of P fertiliser (0, 5, 10 and 20 kg P ha −1 ) was measured on three key low rainfall cropping soils (dune, mid-slope and swale) across a dune-swale system in a low rainfall semi-arid environment in South Australia, for three successive cropping seasons.Wheat on sandy soils produced significant and linear yield and protein responses across all three seasons, while wheat on a clay loam only produced a yield response in a high rainfall season. Responses to P fertiliser were measured on the sandy soils but more variable in nature and a consistent effect of increased P nutrition leading to increased NUE was not measured.

“…In a recent meta-analysis of wheat yield response to N, P, and K fertilizer applications, Duncan et al (2018) highlighted general and significant interactions among nutrients, and how the crop capacity to uptake a given element is enhanced as availability of other elements increases. Consequently, N use efficiency increases as P and K supplies increase.…”

Historically, the agronomic focus of crop mineral nutrition has yielded responses to individual elements (N, P, K…) to determine the economically optimum fertilization rates. This "prognostic" approach required several parameters for crops, climates, and soils that are often estimated with large uncertainty leading to over-fertilization and environmental problems in some systems (e.g., maize in China), and under-fertilization and soil mining in other systems (e.g., wheat in Australia). In this review, an alternative approach is developed for reducing the uncertainty intrinsically linked to this prognostic approach. Our approach is based on four propositions: (1) the evidence of an allometry between the metabolic shoot mass (scaling with leaf area) and the structural shoot mass (supporting and vascular tissues) within plants that allows the formulation of critical N dilution curves and the determination of the Nitrogen Nutrition Index (NNI) for estimating the N nutrition status of field crops; (2) the coregulation of crop N uptake dynamics by both soil N supply and crop N demand in relation with its growth capacity that allows a better, more generalizable estimation of timing and rate of fertilizer; (3) a better understanding of the effects of genotypeenvironment-management interactions on N use efficiency in cropping systems reducing then drastically uncertainties linked to the classical prognostic approach for N fertilization; (4) as P and K also relate allometrically with biomass, P and K concentrations can be directly related to N concentration for the formulation of a multi-element diagnosis of crop nutrition. Here, we develop the theoretical background supporting these four propositions and outline implications for both fertilization management and crop phenotyping.
