The Problem: Our growing world population and the reduction in agricultural land/quality farmable soil are not a sustainable combination. Our food producer--the farmer—daily faces increasingly high costs for water, fertilizer, and implements to grow crops while simultaneously facing declining yields and damaged soil. Soil remediation has become an urgent issue....
Is Irrigation Harming Your Soil? The Relationship Between Water Quality and Soil Health
Understanding Water Quality Problems and How Gypsum Can Help Solve Them In a new report, Dr. Brent Rouppet, Ph.D., explores how your irrigation water can harm your soil, even when you think it is helping your plants. Learn more about your soil's chemistry, how the irrigation water is damaging the...
Getting the most from your gypsum application
Correcting poor soil structure conditions with an application of gypsum can have a significant impact on soil tilth and crop yields. However, many producers overlook this practice because they are not aware of the benefits to soil structure as well as a readily available source of calcium and sulfur. One...
The multiple benefits of gypsum in agriculture
If considering a purchase of calcium sulfate dihydrate (gypsum), it is important to understand the many varied benefits and when they take effect in agriculture. As both a soil amendment and a crop nutrient source, gypsum will remediate sodic soils, help manage saline irrigation waters, provide calcium and sulfur as crop...
Organic growers take note: there is such a thing as organic gypsum
Can gypsum be applied on organic farms? Commercial farmers, organic growers, home owners, turf managers and others can benefit from application of gypsum (calcium sulfate) in remediating salinity and sodium issues and improving soil structure. However they can’t all use the same sources or gypsum for all garden soils. Mined...
What’s your grade? Agricultural or solution?
Agricultural or solution? When reading marketing literature about gypsum, we often see gypsum referred to as solution grade gypsum. This product is primarily targeted for the irrigation market. Is solution grade gypsum any different than conventional gypsum? Gypsum is sold as either powdered ag-gyp or pelletized gypsum. However, ag-gyp can be marketed as...
Pellets, prills, or crushed: the differences explained
Ag Gyp is mined from deposits and is marketed as a powder. It can range in purity from less that 60% to more than 90% on a dihydrate equivalent basis. Since it was ground, it will pass through screen tests ranging from 50 to 200 mesh, and each batch will...
Gypsum & Limestone: two great soil amendments with key differences
Gypsum is calcium sulfate, and lime is calcium carbonate. Both are soil amendments, and both provide calcium. Only gypsum provides a source of sulfur. Gypsum is actively marketed as a soil amendment. Gypsum can be mined. Mined gypsum is a relatively pure and clean product depending on how many other...
Gypsum (calcium sulfate): how it can make degraded soils productive again
Soils in the world degrade generally from human induced activity like logging, mining, drilling (for oil or natural gas), accidental spills or farming. However, nature can also degrade soils with changes in landscape and water levels. Once soils are degraded, they are no longer productive. They cannot support natural vegetation...
How Can I Tell If Gypsum Is Working?
I have been interested in gypsum for nearly a decade now and we have applied it on our family farm in Nebraska – following a 3 year cycle with 1 ton applications every third year. I had heard all the stories how it improves soil structure, particularly in tight clay...
