Gypsum - The Universal Soil Amendment

The most common form of gypsum is dihydrate which means that each molecule of calcium sulfate has two water molecules associated with it. It is expressed as CaSO42H2O. The other form called gypsum anhydrite has no water. Regular use of gypsum is absolutely essential to the sustainability of most irrigated soils. A primary reason for reduction in crop, grass, and hay yields is the failure to apply annual applications of gypsum. Irrigated land eventually leads to sodicity and salinity unless extreme care is taken. Gypsum is a KEY ingredient for the maintenance of agriculture on many types of soil and over a wide pH range, including sodicity. In addition to the prevention and correction of sodicity, gypsum creates greater stability of soil organic matter, more stable soil aggregates, improved water penetration into soil, and more rapid seed emergence. For a variety of reasons, gypsum is considered to be a farmer's best friend. Many of the reasons are multiple and interrelated.

What Does Gypsum Do?

Gypsum is a hydrated form of calcium sulphate which occurs as an "evaporite" deposit, having been formed in the beds of ancient seas and inland lakes as they dry out. Gypsum is a highly sought fertilizer for hay and wheat fields in the United States. Gypsum is used to penetrate heavy soils and subsoils to loosen the soil structure by creating air and moisture fissures that relax and break up the soil structure thereby ameliorating sodic soils. Gypsum provides an excellent option to lift calcium levels below the normal cultivation depth due to various chemical properties in comparison with lime. Gypsum will improve soil structure without raising pH levels. The gypsum mined from our Utah mine deposits usually tests at over 98% pure. Gypsum contains calcium and sulphur which are needed for essential plant growth. For best results, gypsum should be used in conjunction with a regular nutrient fertilizing regime. In addition, we recommend that you continue to apply organic humus as you plant.

Benefits of Gypsum Application on Crops

-Gypsum Helps to Promote Uniform Application - Fertigation facilitates the uniform distribution and precise placement of fertilizer and other amendments.
-Timely Application - In most cases, materials can be applied regardless of weather or field conditions.
-Reduced Application Costs - Generally about one third the cost of conventional application methods.
-Gypsum promotes Improved Management
-Reduced Soil Compaction - Less tractor and equipment traffic in fields reduces compaction.
-Reduced Exposure to Chemicals
-Reduced Environmental Contamination
