“…Surface applying and deep banding gypsum to poorly-drained claypan soils in a conservation tillage system in Northeast Missouri did not consistently increase corn and soybean yields. This lack of response is contrary to some research that has found positive yield responses to applied gypsum or gypsum industrial byproducts (e.g., Chun et al, 2001;Chen et al, 2005,), but others have found no or inconsistent increases in agronomic yields (DeSutter et al, 2014;Kost et al, 2014). Lack of response to gypsum was most likely caused by the low levels of Al +3 in the surface soil and the limited effect of gypsum in altering the soil pH s .…”

Corn (Zea mays L.) and soybean (Glycine max (L.) Merr.) production in claypan soils in the north central U.S. may be constrained by the presence of acidic subsoils. Subsoil acidity can inhibit root growth leading to decreased drought tolerance and grain yields. In conservation tillage systems, management options to incorporate gypsum applications may be limited; thereby reducing available practices to lower subsoil acidity. The objective of this study was to determine the effects of surface placement of gypsum compared to a new practice for deep vertical placement of gypsum on corn and soybean plant growth and yields in a conservation tillage system. Field trials were conducted from 2012 to 2016 in northeast Missouri (USA) with treatments of gypsum (0, 2.9, and 5.2 Mg ha-1) broadcast on the soil surface or applied in a deep vertical band to a depth of 51 cm. Surface and deep banding of gypsum had inconsistent effects on corn and soybean plant heights, plant population and yields. However, deep banding of gypsum resulted in a 6.4 to 9.8% decrease in corn yields and a 9.9 to 13.0% decrease in soybean yields depending on the time after application. These results indicate that further research is warranted in conservation tillage systems in claypan soils to examine modification to the deep vertical placement practice or combining applications of surface-applied gypsum and deep placement of lime in order to develop a practice that will be more effective in overcoming subsoil acidity.

“…Many experiments and studies on the effect and potentiality of FGDB as an amendment in agricultural applications have been conducted by various agencies and research institutes at dispersed locations all over the world [8][9][10][11][12]. Its use in agriculture is mainly based on its liming potential and supply of nutrients which promote growth of plants and alleviate the condition of nutrient deficiency in soils [13][14][15][16].…”

To evaluate the effect of Flue gas desulfurization byproduct( FGDB )as a soil amendment on growth and yield of maize (Zea mays) and to determine the impact of FGDB additions on soil fertility characteristics in alkaline clayey soils, a 2-year field experiment was conducted in Huanghua, in Northern China Coastal Plain. The experiment included five treatments in which the soil was amended with FGDB at 15 cm depth at the rates of 0 t·hm−2, 4.50 t·hm−2, 9.00 t·hm−2, 13.5 t·hm−2, and 18.00 t·hm−2, respectively, before maize was planted. The values of soil pH, exchangeable sodium percentage (ESP), and bulk density (BD) of the soil decreased; however, values of electrical conductivity (EC), water holding capacity (WHC), and plant nutrients increased with FGDB application in the soil. Crop plants grow more readily in FGDB amended soils because of improved soil properties. The best ameliorative effect was obtained at the rate of 13.5 t·hm−2. The germination percentage, plant height, and crop yield successively increased in both years. The results indicated FGDB was an effective soil amendment for improving the physicochemical properties and nutrient balance, and enhancing crop germination, growth, and yield, particularly when applied at a suitable application rate.

“…However, climatic conditions in this area are generally dryer than the eastern and southeastern regions of the United States, and impacts of agricultural FGD gypsum on crops and soils within the Great Plains have been limited. DeSutter et al (2014) applied FGD gypsum and commercial gypsum at rates of 0, 2.24, 11.2, and 22.4 Mg ha -1 to two acid soils (pH values 4.8 and 4.9) in southwestern North Dakota and evaluated soil, wheat yields, and grain chemistry during two growing seasons. Wheat grain yields and element analysis generally were not affected by gypsum.…”

Sustainable Uses of FGD Gypsum in Agricultural Systems: Introduction

Interest in using gypsum as a management tool to improve crop yields and soil and water quality has recently increased. Abundant supply and availability of flue gas desulfurization (FGD) gypsum, a by-product of scrubbing sulfur from combustion gases at coalfired power plants, in major agricultural producing regions within the last two decades has attributed to this interest. Currently, published data on the long-term sustainability of FGD gypsum use in agricultural systems is limited. This has led to organization of the American Society of Agronomy's Community "By-product Gypsum Uses in Agriculture" and a special collection of nine technical research articles on various issues related to FGD gypsum uses in agricultural systems. A brief review of FGD gypsum, rationale for the special collection, overviews of articles, knowledge gaps, and future research directions are presented in this introductory paper. The nine articles are focused in three general areas: (i) mercury and other trace element impacts, (ii) water quality impacts, and (iii) agronomic responses and soil physical changes. While this is not an exhaustive review of the topic, results indicate that FGD gypsum use in sustainable agricultural production systems is promising. The environmental impacts of FGD gypsum are mostly positive, with only a few negative results observed, even when applied at rates representing cumulative 80-year applications. Thus, FGD gypsum, if properly managed, seems to represent an important potential input into agricultural systems.
