Estimating nitrogen, phosphorus, potassium, and sulfur uptake and requirement in soybean

Soybean yield response to sulfur and nitrogen additions across diverse U.S. environments

“…Annual S deposition for the site‐years in the study average 2.3 kg S ha −1 . When this is compared with soybean average uptake of 16−19 kg S ha −1 a deficit of 14–17 kg S ha −1 arises, which must be provided through the soil or fertilizer (Bender et al., 2015; Salvagiotti et al., 2021). The average S concentration in the soils tested was 8.33 mg S kg −1 .…”

“…Despite this trend, synthesis analysis of 207 environments and studies with rates as high as 566 kg N ha −1 did not see positive yield response to higher N rate (Mourtzinis et al., 2018). Additionally, average S uptake has been documented at 16–19 kg S ha −1 , indicating that higher S application rates would not be used or taken up by the plant, but would remain in the soil (Bender et al., 2015; Gaspar et al., 2018; Salvagiotti et al., 2021).…”

“…Ten treatments (Table 1) were replicated four to six times at each site in a randomized complete block design. Fertilizer rates were determined using the average S uptake of 16–19 kg S ha −1 as a guide, rates below, at, and above this range were used (Gaspar et al., 2018; Salvagiotti et al., 2021). A factorial arrangement of three S rates (11, 22, and 33 kg S ha −1 ) using two sources (ammonium sulfate [AMS] [21–0–0–24] and calcium sulfate [CaSO 4 ] [0–0–0–17]) were broadcasted by hand at planting.…”

Yield and nutrient removal of cotton–corn–soybean rotation systems fertilized with poultry litter

“…This shows that including soybean in a rotation would mine these elements from the soil and help in the management of PL application as a fertilizer. The ability of soybean to remove a large amount of K and, to some extent, P is well known (Bender et al, 2015;Mallarino et al, 2011;Salvagiotti et al, 2021). Mallarino et al (2011) showed that soil test P and K declines across years when corn and soybean are grown in rotation without applying P and K fertilizers.…”

Benchmarking Nutraceutical Soybean Composition Relative to Protein and Oil

“…Thus, a synthesis-analysis, by quantitatively combining results from different studies, may overcome those limitations, expanding the level of inference as well as increasing the validity of conclusions (31,32). A similar approach has been previously explored for analyzing relationships between grain yield and a given resource such as water availability (33) or nutrient (N, P, and K) (34) in wheat or in soybean (35)(36)(37).…”
