“…Greater WFPS was associated with greater soil N 2 O peaks in May 2016, as well as May and June 2017, suggesting that gaseous diffusion was restricted and O 2 concentration in the soil was low, which stimulated denitrification (Asgedom et al, 2014). The slow decline in soil water content during the mid‐growing‐season months may have extended anaerobic respiration due to the poorly drained properties of the claypan soil (Zurweller et al, 2015). However, it is difficult to identify reasons for peak soil N 2 O emissions because of the naturally high variability of drainage in claypan soils (Nash et al, 2012).…”

Corn (Zea mays L.) production in poorly drained claypan soils in the US Midwest is a challenge due to low soil permeability, which may result in wetter soil conditions and relatively large amounts of soil N2O emissions early in the growing season. The objectives of this study were to determine the effects of urea fertilizer placement with and without nitrapyrin (NI) on daily and cumulative soil N2O emissions, and yield‐scaled N2O emissions in 2016 and 2017. Treatments included urea deep banded to a 20‐cm depth (DB), urea deep banded to 20 cm plus NI (DB+NI), urea incorporated after a surface broadcast application to ∼8‐cm depth (IA), urea broadcast on the soil surface (SA), and a nonfertilized control (NTC). Fertilizer was applied at 202 kg N ha−1. Surface soil N2O efflux rates were generally lower (<50 g N2O‐N ha−1 d−1) during the first 3 wk after N fertilization and latter parts of the growing seasons. When averaged across the 2016 and 2017 growing seasons, all fertilized treatments had significantly greater (2.33–5.60 kg N2O‐N ha−1, P < 0.05) cumulative soil N2O emissions than NTC. The DB+NI treatment had 54 and 55% lower cumulative soil N2O emissions than IA and SA, respectively. In 2017, DB+NI had similar soil yield‐scaled N2O emissions to NTC. Percentage grain yield increase over NTC was highest for DB and DB+NI. Grain yield in 2016 was 14 to 18% higher for DB and DB+NI than SA. Results suggest that DB+NI is an effective management strategy for reducing cumulative soil N2O emissions and increasing grain yields over the growing season. Core Ideas Deep‐banded urea + nitrapyrin had 55% less soil N2O emissions than surface‐applied. Nonfertilized control and deep‐banded urea + nitrapyrin had similar N2O emissions. Deep‐banded urea + nitrapyrin had a 1.6% lower emission factor than surface‐applied urea. Deep‐banded urea had a 1.0% lower emission factor than surface‐applied urea.

“…Waterlogged soil conditions are favorable for denitrification and gaseous N loss (Zurweller et al, 2015;Ren et al, 2017). Claypan soils have a clay layer that is usually less than 50 cm below the soil surface that causes poor internal drainage (Buckley et al, 2010;Nelson & Smoot, 2012).…”

“…Claypan soils have a clay layer that is usually less than 50 cm below the soil surface that causes poor internal drainage (Buckley et al, 2010;Nelson & Smoot, 2012). These soils are prone to gaseous loss of N fertilizer due to saturated conditions (Nash et al, 2012(Nash et al, , 2015Zurweller et al, 2015). Loss of N to the atmosphere may approach 30% (Wilkison et al, 2000).…”

Nitrification inhibitors have been used to enhance the efficiency of nitrogen fertilizers. This research evaluated the effectiveness of nontreated urea ammonium nitrate (UAN) at 0, 67, 135, 202, and 270 kg N ha -1 as well as UAN treated with nitrification inhibitors (pronitridine at 9.4 and 18.8 L ha -1 or nitrapyrin at 0.5 kg a.i. ha -1 ) to enhance N uptake and increase yield of corn (Zea mays L.). The study took place from 2012-2014 in upstate Missouri on a claypan soil. During the experiments, environmental conditions (high, medium, and low yielding years) affected corn response to pronitridine and nitrapyrin. In general, UAN plus pronitridine at 9.4 L ha -1 had similar effects on corn compared pronitridine at a higher (18.7 L ha -1 ) rate. During a high-yielding year (2014), in order to produce yields equivalent to 67 kg N ha -1 plus pronitridine at 9.4 L ha -1 or nitrapyrin, UAN needed to be increased 14 to 19%. Similarly, the amount of nontreated UAN needed to be increased 8 to 11% for yields to be equivalent to UAN at 135 kg N ha -1 plus pronitridine at 9.4 L ha -1 or nitrapyrin. Grain N removal and agronomic efficiency was highest with pronitridine at 9.4 L ha -1 and nitrapyrin combined with 67 and 135 kg N ha -1 , respectively. This research indicates that pronitridine was as effective as nitrapyrin when added to a pre-emergence application of UAN placed between the rows in a dribble band.

“…Few studies have shown that soil temperature of waterlogged treatments were higher than the nonwaterlogged treatments (Kaur, 2016; Unger et al., 2009). In contrast, Zurweller, Motavalli, Nelson, and Dudenhoeffer (2015) found no differences in soil temperature at a 10‐cm depth between nonwaterlogged and 3‐d waterlogged soils. These changes in redox potential, soil pH, and temperature occurring due to waterlogging ultimately affects N transformation and availability in the soil.…”

Impacts and management strategies for crop production in waterlogged or flooded soils: A review

Globally, flooding is one of the most damaging abiotic stresses, besides drought, that affects 17 million km 2 of land surface annually. Recent research indicates that climate change is resulting in more extreme weather events, such as flooding or soil waterlogging, that negatively affect crop production. Therefore, it is imperative to understand how flooding stress affects crops and to develop improved production practices that make cropping systems more resilient and able to cope with extreme weather events. This review paper summarizes the current state of knowledge on the impacts of flooding or soil waterlogging on crop production losses, nitrogen (N) losses, and provides potential management strategies to reduce these losses. The factors affecting the extent of flooding injury in plants as well as plant adaptations under waterlogging stress are also discussed briefly. For the purpose of this review, "flooding" refers to the situation when all or part of the plant is submerged under water, whereas "soil waterlogging" refers to the situation where soil pores are saturated with water. Soil waterlogging also promotes soil N losses through runoff, leaching, and denitrification. Potential management practices that can be used to mitigate soil waterlogging stress include the use of flood-tolerant varieties, adjusting management practices, improving drainage, and practicing adaptive nutrient management strategies. However, these might be site-or crop-specific management practices and they should be validated for their economic viability before developing future management plans that promote sustainable crop yields from waterlogged soils.Abbreviations: BMP, Best Management Practice; CDSI, controlled drainage and subirrigation; EEF, enhanced efficiency fertilizer; ET, evapotranspiration; Fv/Fm, ratio of variable fluorescence to material fluorescence; GIS, Geographic Information System; NBPT, N-(n-butyl) thiophosphoric triamide; NI, nitrification inhibitor; NUE, nitrogen use efficiency; PCU, polymer-coated urea; UI, urease inhibitors.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.
