Why is gypsum used as fertilizer?

Gypsum is one of the earliest forms of fertilizer used in the United States. Gypsum is a moderately soluble source of the essential plant nutrients, calcium and sulfur, and can improve overall plant growth.

How does gypsum improve soil?

Gypsum improves soil structure by displacing sodium (and magnesium) on the surface of clay particles with calcium. Gypsum (calcium sulfate) is sparingly soluble, but the sodium (and magnesium) sulfates that form in the soil solution are very soluble. They add to the overall concentration of soluble salts in the soil.

Why gypsum is used in agriculture?

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. When we apply gypsum to soil it allows water to move into the soil and allow the crop to grow well.

What are the benefits of gypsum?

Here are five key (and overlapping) benefits of gypsum highlighted at past symposiums:

• Source of calcium and sulfur for plant nutrition.
• Improves acid soils and treats aluminum toxicity.
• Improves soil structure.
• Improves water infiltration.
• Helps reduce runoff and erosion.

What plants benefit from Gypsum?

Gypsum is an Excellent Source of Calcium

• Discolored patches on fruits, such as blossom end rot on tomato plants, peppers, melons or squash.
• Dead buds and root tips.
• Shedding of blossoms or buds prematurely.
• Weak stems.
• Abnormal dark green leaves.
• Burnt tips on the young leaves of celery, lettuce or cabbage.

When should you apply gypsum?

Gypsum neutralizes the mineral salts in pet urine, resolving odors and preventing lawn damage. Gypsum may be applied any time of year and, depending on the needs of your particular lawn, we may apply it two to three times a year.

What plants benefit from gypsum?

Can you mix gypsum and fertilizer together?

Pelletized gypsum (calcium sulfate) can be easily blended with today’s dry fertilizer materials including urea, ammonium sulfate, diammonium phosphate (DAP) or monoammonium phosphate (MAP).

Is gypsum good for vegetable garden?

Gypsum is non-toxic and safe to use around people and pets. It works well throughout the yard or garden and can be applied to lawns, in vegetable or flower gardens, and around trees and shrubs.

How do I know if my lawn needs gypsum?

Test your soil to determine whether applying gypsum will be helpful. Many local university extension offices offer soil testing for a minimal charge. If your soil tests high for sodium or low for calcium, or is made up of highly compacted clay, your lawn might be a candidate for a gypsum application.

Can you put gypsum around plants?

When should I apply gypsum to my garden?

It is useful in changing the soil structure of excessively heavy soils which have been impacted by heavy traffic, flooding, overcropping, or simply overly weatherized. One of the main uses of gypsum is to remove excess sodium from the soil and adding calcium.
