“…Of which, North America constituted 14.1 million tonnes in 2015, and the demand for N fertilizer is expected to reach 14.6 million tonnes in 2019 (see Figure 1B). Although large amounts of N fertilizers were used throughout the world, the recovery or efficiency of N fertilizers by crops in arable lands is relatively low, ranging from 25% to 50% of the applied N [3,4]. Low nitrogen use efficiency (NUE) may lead to an alarming situation from environmental, economic, and resource conservation points of view, and suggests an urgent need for improving N use efficiency (NUE) of fertilizers.…”

Management of nitrogen (N) is a challenging task and several methods individually and in combination are in use to manage its efficiency. However, nitrogen use efficiency (NUE) has not been improved to a level, only 33%, as predicted by the researchers while developing nitrogen management tools and methods. The primary objective of this review article is to evaluate methods and tools available to manage nitrogen. Several methods, soil testing, plant tissue testing, spectral response, fertilizer placement and timing and vegetative indexes (leaf area index, and NDVI) through drones, handheld sensors, and satellite imagery were reviewed on the subject of user-friendly and effectiveness towards NUE. No single method was found sufficient to counter the nitrogen loss. Some methods were found time consuming and unsynchronized with N uptake behavior of particular crop, for example, plant tissue testing. Use of precision agriculture tools, such as GreenSeeker, Holland Crop Circle, drone, and satellite imagery, were found better compared to conventional methods such as soil testing, but these tools can only be used when the crop is up. Therefore, N management is possible only through inseason N application methods. When 70% of the applied nitrogen is used by the crops within 25-30 days after planting, for example, corn and potatoes, it is required to apply major N rates through inseason approach and some N at planting using soil test reports. In conclusion, this article strongly advocates using two or more methods in combination when managing N.

“…He hypothesized that the dissolving granule left a cavity in which the ES settles as an aggregate, resulting in less available ES surface with increasing granule size because the total number of granules for a given fertilizer rate is smaller as the granule size is larger. In a recent review paper, Chien et al (2016) pointed out that cogranulated ES products are usually less effective in the short term than ES particles mixed through soil, which was attributed to a "negative locality effect, " but this effect was not quantified. In a recent study (Degryse et al, 2016), we compared the oxidation of granular ES fertilizers and ES particles in three soils.…”

Most studies on elemental sulfur (Es) oxidation have focused on small Es particles mixed through soil, even though commercial Es fertilizers are usually in granular form. Although it has been recognized that cogranulation of Es decreases its oxidation rate, no attempt has been made to quantify this effect. We developed a conceptual model that predicts the "effective diameter" (the diameter of Es particles mixed through soil that would oxidize at the same rate as the granulated Es) by taking into account the effect of granulation on the effective surface area available to the Es in the granule cavity after the soluble macronutrient compound in the fertilizer has diffused away. To validate the model, the oxidation rate was determined for Es-fortified monoammonium phosphate fertilizer with varying Es content (20-250 g kg −1 ), Es particle diameter (25 or 60 mm), and granule diameter (1.8 or 3.4 mm). The time to reach 50% oxidation varied from 17 d for small granules at the lowest Es content to 210 d for the large granules with the highest Es content. In agreement with the model predictions, reducing Es particle size did not affect the oxidation rate except at the lowest Es rate, whereas reducing granule size increased the oxidation rate. Predicted and observed oxidation rates were in good agreement, indicating that the model describes the effect of granulation with reasonable accuracy. This model may assist in improving formulation of Es-containing fertilizers and guiding fertilizer recommendations.Abbreviations: ES, elemental sulfur; MAP, monoammonium phosphate; TSP, triple superphosphate. E lemental sulfur (ES) is a common S fertilizer source. Elemental S is insoluble in water and hence is not susceptible to leaching and also has the benefit of lower transport/handling costs because it is the most concentrated form of S. However, ES only becomes available to plants when it is oxidized to sulfate (Boswell and Friesen, 1993). Knowledge of the factors that affect ES oxidation is hence required to develop fertilizer recommendations for ES-containing fertilizers.The oxidation of ES particles is affected by biological, fertilizer, and soil-related factors (Germida and Janzen, 1993). Because ES oxidation is a biologically mediated process, it is strongly influenced by temperature. Janzen and Bettany (1987a) assessed ES oxidation in six soils in Saskatchewan, Canada, at temperatures ranging between 3 and 30°C and found Q 10 values (factor increase per 10°C increase) ranging from 3.2 to 4.3. Oxidation of ES is a surficial process, and the rate of oxidation is therefore proportional to the specific surface area of the ES particles. Soil properties also affect the oxidation rate, likely through their effect on the composition and abundance of the microbial community. For instance, Zhao et al. (2015) found that the surface-based oxidation rate of ES in 10 Australian soils ranged between 5 and 52 mg cm −2 d −1 and was positively correlated with the pH and organic matter content of the soil.

“…Grain S concentrations in the current study (3.03–3.29 g kg −1 ) suggest adequate S supply regardless of seeding rate and fertilizer treatment. Delayed S availability with elemental S, grain S requirements that rely on continuous soil uptake past grain‐fill, direct partitioning of nutrients accumulated past R5.5 to grain, and a large S HI (70%) may have increased grain S accumulation with MESZ applications (Chien et al., 2016; Gaspar et al., 2018). However, grain S accumulation may also be dependent on early‐season nutrient uptake and remobilization efficiency from vegetative and other reproductive tissues (Sunarpi & Anderson, 1997; Naeve & Shibles, 2005).…”

“…Potential for a grain yield increase to fertilizer applications may be dependent on site‐specific factors (i.e., soil and physical properties and precipitation) (Clover & Mallarino, 2013; Hankinson, Lindsey, & Culman, 2015; Warncke et al., 2009). However, grower interest in N, P, K, S, and Zn applications continues to increase due to volatile spring environmental conditions, variable soil texture, decreased atmospheric S deposition in the north‐central United States, perceived increases in micronutrient deficiencies, and to ensure yield potential of modern higher‐yielding cultivars (i.e., yield potential >4500 kg ha −1 ) (Chien et al., 2016; Havlin et al., 2014; Hitsuda, Toriyama, Subbarao, & Ito, 2008; Osborne & Riedell, 2006; Sutradhar, Kaiser, & Behnken, 2017; Tamagno, Sadras, Haegele, Armstrong, & Ciampitti, 2018). Gaspar, Laboski, Naeve, and Conley (2017b) reported grain K requirements relied on vegetative remobilization past R5.5 emphasizing the importance of K tissue concentrations to support soybean DM and K accumulation prior to grain‐fill.…”

Greater soybean (Glycine max L. Merr.) total dry matter (TDM) production may support yield potential and correspondingly drive greater nutrient uptake. Whether increased dry matter (DM) and reduced interplant competition at decreased seeding rates improves grain yield response to fertilizer applications is not clear. A 3-site-year trial was conducted to evaluate soybean seeding rates and fertilizer applications on plant growth, nutrient accumulation, grain yield, and economic return. Seeding rates included: 123,500; 222,400; 321,200; and 420,100 seeds ha −1 . Fertilizer applications consisted of: unfertilized; 90 kg MOP (0−0−62 N−P−K) ha −1 pre-plant incorporated (PPI); 168 kg MESZ (12-40−0−10−1 N−P−K−S−Zn) ha −1 applied 5 by 5 cm below and to the side of the seed at planting (5 × 5); and 90 kg MOP ha −1 PPI and 168 kg MESZ ha −1 applied 5 × 5. Dry matter (V4) increased 37.7 to 116.6% and 73.3 to 137.5% with seeding rates ≥222,400 seeds ha −1 and MESZ applications, respectively, with greater early-season DM supporting increased nutrient uptake and grain yield potential. Increasing seeding rate from 123,500 to 222,400 seeds ha −1 improved grain yield 9% but no differences were observed above 222,400 seeds ha −1 .The MESZ and MOP+MESZ applications increased grain yield 7.4 and 6.9%, respectively, while MOP did not affect grain yield across site-years. As emphasis on creating more durable, resilient agroecosystems continues, results suggest seeding rates ≥222,400 seeds ha −1 maximized DM accumulation facilitating nutrient uptake which may be paramount to improving fertilizer management or reducing post-harvest residual soil nutrients in impaired watersheds or regions of greater nutrient loss potential.
