Flue gas desulfurization (FGD) gypsum, a coal combustion by-product, can be used to decrease water-extractable soil P, thereby lowering the potential for P export to surface waters. This decrease results from a conversion of loosely bound inorganic P (IP) which is readily desorbable to water, to less soluble Al- and Fe-bound IP and, to a lesser …
gypsum, can decrease water-extractable soil P without to 1 yr) occurs during the 21-d period (Rajan and Fox appreciably decreasing plant available P (i.e., 1972; Sharpley 1982). Recent work has shown that Mehlich-1 or -3 soil P) (O'Reilly and Sims 1995; decreases in water-extractable P caused by FGD Stout et al. 1998).
The application of gypsum reduces Mg and K foliar contents and increases Ca, Z, and Mn contents in the two crops. Gypsum increases the SPAD index in soybean plants. The increase in the gypsum doses leads to a N - K ratio unbalance in corn leaves and reduces the crop leaf area. Doses of P and gypsum do not influence yields of soybean and corn …

Field application of gypsum (CaSO4 × 2H2O) is a tool to decrease phosphorus (P) load to watercourses. Effects of gypsum application (4 tons ha-1) on soil and crop composition were monitored up to four years after the treatment in the Savijoki catchment, southwestern Finland. Eleven amended fields and 17 control fields were …
About Phosphor-Gypsum: Phosphorus is a mineral critical to all life on Earth. As a requirement of all biological beings, it is a cornerstone of nutrition for plants, animals, and people. Phosphogypsum is a waste by-product from the processing of phosphate rock in plants producing phosphoric acid and phosphate fertilizers, such as …
Most plants absorb phosphorus best in a slightly acidic to neutral pH range. If your soil is too alkaline or too acidic, it can inhibit phosphorus availability, regardless of how much is present ...
Is Gypsum Good for Native Plants? OK, so this bit is where the science gets a bit confusing, but the short version is that yes, gypsum is good for most native plants, even those with phosphorus sensitivities. Phosphorus sensitivity and phosphorous toxicity in native Australian plants can lead to blacked leaves, dropped …
Gypsum: 1% Corn cobs, cocoa shells, cotton seed hulls ... and phosphorus, which are essential for plant growth. The key is to identify which salts are contained within a given compost, their levels, and whether or not they are beneficial to plant heath. In general, compared to chemical fertilizer and raw manures, the soluble salts in compost ...
Groundnut, being a legume oilseed crop, requires a significant amount of phosphorus. Plants use it for energy transfer in metabolic processes such as photosynthesis (in the form of ATP and ADP ...

POCATELLO — Improvements to stop phosphorus releases from J.R. Simplot Co.'s local Don Plant into the Portneuf River are now between two and three years ahead of schedule, estimates Bruce
Sulfur (S) is an essential macronutrient for plant growth and development. S is majorly absorbed as sulfate from soil, and is then translocated to plastids in leaves, where it is assimilated into organic products. Cysteine (Cys) is the first organic product generated from S, and it is used as a precursor to synthesize many S-containing …
The experiments comprising of 9 treatments, viz. Phosphorus at 40, 50 and 60 kg/ha along with 3 levels of Gypsum at 200, 300 and 400 kg/ha. It was laid out in a Randomized Block Design and replicated thrice. Maximum plant dry wei ght was recorded with Phosphorus 60 kg/ha along with Gypsum 400 kg/ha.
1. Introduction. Gypsum is a material widely employed in the construction industry due to its excellent properties such as low thermal conductivity, light weight, fire resistance, and relative ease of handling [1], [2].Phosphogypsum, a byproduct from the processing of phosphate rock, is chemically similar to natural gypsum and holds a …
