“…Studies that examine the extent and magnitude of crop response to S fertilization (e.g., Brooks et al., 2022; de Borja Reis et al., 2021; Goyal et al., 2021) should consider the application of granular P fertilizers prior to the crop being studied as a possible factor obviating the need for, or reducing crop response to, direct S fertilization. Dismissing the potential contribution of P fertilizers to satisfy the S needs of crops, seems unwise given that when applied at a rate to replace grain P removal of both crops in a corn and soybean rotation, the P fertilizers can supply 50% or more of grain S removal of the subsequent crop.…”

The occurrence of S deficiency in Midwest crops in the past 20 years is likely a result of the consistent decline of atmospheric S deposition during this time period. In the absence of intentional S fertilization, crops utilize SO4‐S mineralized from soil organic matter and potentially also the incidental application of S in non‐S fertilizers. Based on the analysis of hundreds of P fertilizer samples in 2021 and 2022 we found monoammonium phosphate (MAP), diammonium phosphate (DAP), triple superphosphate (TSP), and ammonium polyphosphate (APP) had SO4‐S concentrations of 1.88 ± 0.35, 1.80 ± 0.30, 1.66 ± 0.27, and 0.61 ± 0.18% SO4‐S (mean ± standard deviation). If MAP, DAP, and TSP are applied to replace P removal of average yielding corn (Zea mays L.) and soybean (Glycine max L.) crops grown in rotation, SO4‐S applied by MAP, DAP, and TSP at median and 3rd quartile values would be 4.0 to 4.6 lb SO4‐S acre−1, approximately equivalent to ∼42 to 52% of the S removed in the grain of a single crop. If used as a starter fertilizer (5 gal acre−1) APP would apply <0.4 lb acre‐1, <4% of grain S removal. The crop availability of SO4‐S in P fertilizers is conditional on the timing of their application relative to crop need, soil properties, and rainfall in addition to the amount of S applied. The contribution of P fertilizers to S cycling in environmental studies should also be considered.This article is protected by copyright. All rights reserved

“…In this study, elemental S accounted for half of the S application, which was also a significant factor contributing to the reduced SUE. To accelerate the rate of elemental S oxidation, the use of elemental S with a smaller particle size or inoculated with S-oxidizing bacteria has gained broad attention [56,65,66]. The application of elemental S combined with organic amendments such as poultry and farmyard manure could also increase S oxidation and availability due to improved microbial activity [34].…”

Sulfur (S) deficiency is becoming increasingly prevalent, posing a serious threat to crop yield and quality. The incorporation of S fertilizers into macronutrient fertilizers such as ammonium phosphate represents a straightforward and economically efficient approach to alleviating S deficiency, strengthening S supply, and improving crop yield. However, limited research has been conducted to assess the effect of monoammonium phosphate (MAP) and diammonium phosphate (DAP) with different S additions on agronomic outcomes. In this study, ammonium sulfate and elemental S with S set at 3%, 6%, 9%, and 12% (ensuring a 1:1 ratio of SO4−S to elemental S) were granulated with MAP and DAP, respectively. Maize was used as the test crop to evaluate its yield, nutrient uptake, and apparent sulfur recovery. The results showed that S-fortified MAP treatment increased crop yield and S uptake by an average of 9.3% and 10.6%, respectively. A significant difference in crop yield and S uptake was observed when the S addition in MAP exceeded 9% S. Nevertheless, no statistical difference was found among the DAP-based treatments in calcareous soil. There was a strong relationship between S applied in fertilizers and S uptake by crops for MAP-based treatments. However, the apparent sulfur recovery drastically dropped from 44.2% to 7.19% with the increased addition level of S for MAP-based fertilizers. The results of this study indicate that the addition of S to MAP could be a simple, low-cost, and effective approach with great potential to promote S fertilizer application, minimize soil S deficiency, and improve crop yield in calcareous soil.

“…Soil extractable S, the most routinely measured diagnostic test in farmer fields in the Midwest, has not been a reliable indicator of S deficiency because of the complex biotic and abiotic factors that govern S mineralization (Dick et al., 2008; Kaur et al., 2019; Pagani & Echeverria, 2011). Studies from North Dakota reported that no soil factors, including SOM and Mehlich‐3 extractable S were good indicators of yield response following S application (Franzen & Grant, 2015; Goyal et al., 2021). In Minnesota, a negative correlation between soybean yield and soil S was reported (Kaiser & Kim, 2013).…”

Ohio grain crop response to sulfur fertilization

Continuous declines in atmospheric sulfur (S) deposition along with increased S removal rates with crop harvest has the potential to lead to S deficiency in Ohio field crops. As a result, S fertilization has become more common over the past decade.However, the extent of S deficiency is unknown, as inherent soil properties and management practices influence S availability and uptake. We conducted 96 replicated trials, from 2013 to 2021 to (1) examine the response of corn (Zea mays L.), soybean [Glycine max (L.) Merr], and wheat (Triticum aestivum L.) to S application on a wide range of Ohio soils and differing management practices and (2) determine the ability of Mehlich-3 extractable S in soil, leaf S, and grain S concentrations to predict grain yield response to S fertilizer. Our results showed limited grain yield increases to S fertilization with an overall response rate of 7.3% (4 of 50 corn trials, 3 of 34 soybean trials, and 0 of 12 wheat trials). Sulfur fertilization increased leaf and grain S concentrations by 19.4% and 12% in corn, by 22.2% and 7.7% in soybean, and by 41.7% and 0% in wheat, respectively. These increases in leaf or grain S concentrations were not directly related to yield responses. Diagnostic tools of Mehlich-3 soil S, leaf S, and grain S concentrations failed to predict yield response to S. We conclude that S deficiency is not widespread in Ohio soils and that optimizing grain crop production does not currently require S fertilization. INTRODUCTIONSulfur (S) is essential for numerous plant processes but has not been traditionally applied to agricultural soils in the Midwest (Dick et al., 2008). Historically, relatively large rates of S were supplied from atmospheric deposition in readily available forms for plant absorption (Dick et al., 2008
