There is renewed interest in the application of gypsum to agricultural lands, particularly of gypsum produced during flue gas desulfurization (FGD) at coal-burning power plants. We studied the effects of land application of FGD gypsum to corn ( L.) in watersheds draining to the Great Lakes. The FGD gypsum was surface applied at 11 sites at rates of 0, 1120, 2240, and 4480 kg ha after planting to 3-m by 7.6-m field plots. Approximately 12 wk after application, penetration resistance and hydraulic conductivity were measured in situ, and samples were collected for determination of bulk density and aggregate stability. No treatment effect was detected for penetration resistance or hydraulic conductivity. A positive treatment effect was seen for bulk density at only 2 of 10 sites tested. Aggregate stability reacted similarly across all sites and was decreased with the highest application of FGD gypsum, whereas the lower rates were not different from the control. Overall, there were few beneficial effects of the FGD gypsum to soil physical properties in the year of application.

“…Gypsum is an excellent source of calcium (Ca) and sulfur (S) for plant nutrition, as Ca 2+ and SO 4 2− ions become readily available in soil solution after its application (Shainberg et al, 1989; Chen and Dick, 2011). Recently, there has been an enhanced interest in using gypsum as a S source due to a potential for S deficiency in crops resulting from reduced S inputs (Chen et al 2005, 2008; Buckley and Wolkowski, 2012; Kim et al, 2013; Steinke et al, 2015; Sutradhar et al, 2017).…”

Effects of Gypsum Application Rate and Frequency on Corn Response to Nitrogen

The effects of gypsum as a soil amendment and its interaction with nitrogen (N) applications in corn (Zea Mays L.) production are largely unknown. A 4-yr field study was conducted in Ohio, USA to evaluate (i) the effects of gypsum rates and rate frequencies at varying fertilizer N rates on corn grain yields, ear-leaf and grain nutrient concentrations, and on soil nutrients, and (ii) the interactive effects between N and gypsum applications. A splitplot experimental design was used with N rates (0, 84, 168, and 252 kg N ha -1 ) as the main plot factor and either gypsum application rate (0, 1.1 and 2.2 Mg ha -1 ) or application rate frequencies (i.e., 1.1 Mg ha -1 annually, 2.2 Mg ha -1 bi-annually, and 4.4 Mg ha -1 once every four years) as subplot factors. Overall, corn yield response to gypsum applications was inconsistent. A positive corn yield response to gypsum application occurred only in 2017 at the Northwest site. Gypsum applied at 4.4 Mg ha -1 significantly decreased yields at the Northwest site in 2017 and at the Wooster site in 2016 suggesting that the best management strategy may be to apply lower gypsum rates either annually or biannually. Gypsum applications did not improve corn response to N at either study site but significantly increased tissue, grain and extractable soil S concentrations with concentrations decreasing as the application frequency decreased. This suggests that where S deficiencies may occur, an annual rate of 1.1 Mg ha -1 or a bi-annual application of 2.2 Mg ha -1 would increase S availability. ). core Ideas• Corn response to N at different gypsum application rates and frequencies was evaluated. • Gypsum did not improve corn response to N at any of the study sites.• Corn yield response to gypsum applications was very inconsistent and site-specific. • Frequent gypsum applications at lower rates were better than a onetime large application.

Phosphorus runoff from agricultural land to surface water bodies, such as the Great Lakes, is an important environmental concern. Soil amendments, such as gypsum, may alter the chemistry of the soil solution to reduce the amount of water‐soluble P (WSP) available for loss to runoff, and as such, the NRCS now recommends gypsum application as a Conservation Practice Standard (Code 333) for improving water quality. Interest in gypsum use has also increased as availability has increased from production of flue gas desulfurization (FGD) gypsum at many coal‐burning power plants throughout the United States. This study tested three rates of unincorporated, surface‐broadcast FGD gypsum application at 23 field sites in Wisconsin. The optimal rate for reducing WSP concentration and the relationship between selected soil properties and the beneficial effect of FGD gypsum application were evaluated. The FGD gypsum reduced WSP (P < 0.0001), with a significant effect compared with the control at the lowest tested rate of 1120 kg ha−1 at 5 of the 23 sites. Few other sites saw a significant benefit. Correlation indicated that sites showing a beneficial reduction of WSP from FGD gypsum application were those with greater soil test P (P = 0.0002) and lower cation exchange capacity (P = 0.0087) values. Core Ideas Not all sites benefit from flue gas desulfurization (FGD) gypsum application. FGD gypsum is useful in reducing water‐soluble P in soil and the potential for P in runoff. Sites with high soil test P and low cation exchange capacity benefit more from FGD gypsum.
