The Role Of Gypsum In Agriculture: 5 Key Benefits You Should Know

While farmers have used gypsum (calcium sulfate dihydrate) for centuries, it has received renewed attention in recent years. This resurgence is due in large part to ongoing research and practical insights from leading experts that highlight the many benefits of gypsum.

The latest information on gypsum was the focus of the third annual Midwest Soil Improvement Symposium in Ada, OH, in March. The one-day event was held in conjunction with The Ohio State University’s Conservation Tillage and Technology Conference and sponsored by GYPSOIL — a leading supplier of synthetic gypsum. More than 200 attendees heard from industry representatives, scientists, consultants and growers on the use of gypsum to improve soil structure, reduce nutrient runoff and more.

Major Benefits Of Gypsum

Here are five key (and overlapping) benefits of gypsum highlighted at the symposium:

1. Source of calcium and sulfur for plant nutrition. “Plants are becoming more deficient for sulfur and the soil is not supplying enough it,” said Warren Dick, soil scientist and professor, School of Environment and Natural Resources, The Ohio State University. “Gypsum is an excellent source of sulfur for plant nutrition and improving crop yield.”

Meanwhile, calcium is essential for most nutrients to be absorbed by plants roots. “Without adequate calcium, uptake mechanisms would fail,” Dick said. “Calcium helps stimulate root growth.”

2. Improves acid soils and treats aluminum toxicity. One of gypsum’s main advantages is its ability to reduce aluminum toxicity, which often accompanies soil acidity, particularly in subsoils. Gypsum can improve some acid soils even beyond what lime can do for them, which makes it possible to have deeper rooting with resulting benefits to the crops, Dick said. “Surface-applied gypsum leaches down to to the subsoil and results in increased root growth,” he said.

3. Improves soil structure. Flocculation, or aggregation, is needed to give favorable soil structure for root growth and air and water movement, said Jerry Bigham, Professor Emeritus, School of Environment and Natural Resources, The Ohio State University. “Clay dispersion and collapse of structure at the soil-air interface is a major contributor to crust formation,” he said. “Gypsum has been used for many years to improve aggregation and inhibit or overcome dispersion in sodic soils.”

Soluble calcium enhances soil aggregation and porosity to improve water infiltration (see below). “It’s important to manage the calcium status of the soil,” he said. “I would argue it’s every bit as important as managing NPK.”

In soils having unfavorable calcium-magnesium ratios, gypsum can create a more favorable ratio, Bigham added. “Addition of soluble calcium can overcome the dispersion effects of magnesium or sodium ions and help promote flocculation and structure development in dispersed soils,” he said.

4. Improves water infiltration. Gypsum also improves the ability of soil to drain and not become waterlogged due to a combination of high sodium, swelling clay and excess water, Dick said. “When we apply gypsum to soil it allows water to move into the soil and allow the crop to grow well,” he said.

Increased water-use efficiency of crops is extremely important during a drought, added Allen Torbert, research leader at the USDA-ARS National Soil Dynamics Lab, Auburn, AL. “The key to helping crops survive a drought is to capture all the water you can when it does rain,” he said. “Better soil structure allows all the positive benefits of soil-water relations to occur and gypsum helps to create and support good soil structure properties.”

5. Helps reduce runoff and erosion. Agriculture is considered to be one of the major contributors to water quality, with phosphorus runoff the biggest concern. Experts explained how gypsum helps to keep phosphorus and other nutrients from leaving farm fields. “Gypsum should be considered as a Best Management Practice for reducing soluble P losses,” said Torbert, who showed studies on how gypsum interacts with phosphorus.

Darrell Norton, retired soil scientist at the USDA-ARS National Soil Erosion Research Laboratory at Purdue University, added: “Using gypsum as a soil amendment is the most economical way to cut the non-point run-off pollution of phosphorus.”

  1. The symposium speakers included spporting data in their presentations. You can find videos of all the presentations given at the 2013 symposium by going to the GYPSOIL website at this link:http://www.gypsoil.com/improving-your-soil/midwest/midwest-soil-improvement-symposium/2013-symposium

    Also, GYPSOIL maintains a large Research Library of peer-reviewed research papers; proceedings, bulletins and research reports; slide sets and popular press articles at the link below. It is easy to search the Library for specific topics pertaining to gypsum such as water infiltration, aluminum toxicity, sulfur, erosion, etc. You can also search by state and researcher name. Find the Library at this link: http://www.gypsoil.com/research-library?&filterCrop=&filterFocus=&filterState=&filterCategory=&filterKeyword=&pagenum=6

  2. Could I mix the Gypsum into the NPK mixtures? Is Gypsum suitable to use in Tropica soil, for Palm oil Tree?

  3. Dear sir or madam.
    It is nice to know gypsum use as agricultural input
    What is the prosses?
    If we produce it who is buying?
    Regards.
