“…Both crops have a high N export with grains (Piccinetti et al 2021), as re ected by N harvest indexes above 75% and 64% in soybean and maize, respectively (Salvagiotti et al 2008;Setiyono et al 2010;Tamagno et al 2017). Negative N balances are usually observed in maize because the high N outputs with the harvested grains are not compensated by N inputs through fertilization (Correndo et al 2021). In soybean, local reports indicated that N inputs via biological N xation (BNF) can meet plant N requirements (Collino et al 2015).…”

Purpose The inclusion of winter legumes during fallow periods allows the addition of N to the system through biological N fixation (BNF), which will depend on management practices and crop species (for grain production or a cover crop). The objectives of this study were to evaluate the BNF and biomass and N accumulation in pea and vetch crops growing under field conditions and to study the impact of including belowground structures in the partial N balance of both crops. Methods Biomass, BNF and N uptake, including belowground structures (determined in field monoliths to 0.3m depth), were quantified in a two-year field study evaluating two genotypes (semi-leafless and conventional-leaved) in field pea, and contrasting sowing dates in vetch. Results Belowground BNF inputs improved the partial N balances and averaged 1 and 4 kg N ha− 1 in field pea and vetch, respectively. The partial N balance in field pea was negative in most cases (average − 7 kg N ha− 1), determined to a greater extent by a high NHI, while in vetch net N inputs increased with the delay of sowing date (from 60 to 295 kg N ha− 1). Conclusions In field pea, the different genotypes exerted minor effects on biomass and %Ndfa, whereas in vetch sowing dates had a strong impact on these variables. BNF-derived N at full bloom in vetch proved to be higher when delaying sowing dates, despite plants reaching lower total biomass with a higher partial N balance.

“…In Argentina, fertiliser use over the last 20 years has increased but remains low-to-medium for world standards (Norton et al, 2015;Garcıá and Gonzaĺez Sanjuan, 2016). Under fertilisation of grain crops is apparent in soil mining at an estimated rate of 15 to 45 kg N ha -1 yr -1 , and higher rates of fertilisation are critical to improving grain yield and the efficiency in the use of water and radiation (Caviglia et al, 2019;Correndo et al, 2021a). Most nitrogen recommendations are based on empirical functions relating grain yield and soil nitrogen (frequently NO 3 -N in the top 0.6 m) plus nitrogen fertiliser, which provides a critical nitrogen above which the probability of response to fertiliser is low (Pagani et al, 2008;Dıáz Valdez et al, 2020;Correndo et al, 2021a).…”

Nitrogen management is central to the economic and environmental dimensions of agricultural sustainability. Yield response to nitrogen fertilisation results from multiple interacting factors. Theoretical frameworks are lagging for the interaction between nitrogen and air temperature, the focus of this study. We analyse the relation between yield response to nitrogen fertiliser and air temperature in the critical period of yield formation for spring wheat in Australia, winter wheat in the US, and maize in both the US and Argentina. Our framework assumes (i) yield response to nitrogen fertiliser is primarily related to grain number per m2, (ii) grain number is a function of three traits: the duration of the critical period, growth rate during the critical period, and reproductive allocation, and (iii) all three traits vary non-linearly with temperature. We show that “high” nitrogen supply may be positive, neutral, or negative for yield under “high” temperature, depending on the part of the response curve captured experimentally. The relationship between yield response to nitrogen and mean temperature in the critical period was strong in wheat and weak in maize. Negative associations for both spring wheat in Australia and winter wheat with low initial soil nitrogen (< 20 kg N ha-1) in the US highlight the dominant influence of a shorter critical period with higher temperature; with high initial soil nitrogen (> 120 kg N ha-1) that favoured grain number and compromised grain fill, the relation between yield response to nitrogen and temperature was positive for winter wheat. The framework is particularly insightful where data did not match predictions; a non-linear function integrating development, carbon assimilation and reproductive partitioning bounded the pooled data for maize in the US and Argentina, where water regime, previous crop, and soil nitrogen overrode the effect of temperature on yield response to nitrogen fertilisation.

“…For a given soil test, critical soil concentrations below which fertilisation is recommended, depend on e.g. soil texture or pH (Correndo et al, 2021;Jordan-Meille et al, 2012;Steinfurth et al, 2022). Consequently, to provide reliable fertiliser recommendations, these curves should be derived for a large range of crops grown on a wide range of soil types and under various climatic conditions.…”

“…Nutrient supply is affected by several other (soil) properties which were not included in our analyses. Texture, soil type, bulk density and rooting depth significantly affect nutrient and water availability, which can all impact plant nutrient uptake, yields and fertiliser response (Correndo et al, 2021;Leenaars et al, 2018). Rainfall/water availability furthermore is known to affect B leaching .…”
