What is Lawn Cal?
Uncle’s Lawn Cal is an agricultural grade pelletized gypsum, an excellent source of calcium and sulfur for lawn or garden. Calcium is essential for healthy soil and vigorous plant growth. Used as a soil amendment, Lawn Cal reduces compaction by improving water and air penetration, which in turn counteracts the effects of salt and other excessive elements in the soil. Lawn Cal is an inexpensive granular treatment that can be applied with a home or professional rotary spreader. Lawn Cal can be used at any time of year when the ground is not frozen.
Benefits of Adding Calcium to Lawns
- Loosens compacted soils
- Aids fertilizers to penetrate the ground and be more available to the plant
- Calcium is essential for nutrient absorption through plant roots
- Stimulates microorganism growth
- Improves water penetration into and through the soil
- Enhances the value of the organic matter in the soil
- Assists in moving harmful salts through the soil, such as animal urine and ice melter
Lawn Cal Helps Compacted Soils
There can be multiple reasons why soil is compacted. Heavy machinery during construction, heavy foot traffic, and dog runs are just a few. These conditions can be made worse with heavy clay soils. Applying lawn calcium to a compacted yard works to break down the bulk density of the soil, relieving compaction will provide a better growing environment for your grass.

How to Reduce Salt Damage in Plants
When salt is applied to roads, sidewalks, and driveways during icy winter months, the effects can be long-lasting to the surrounding soil and plants. Large amounts of salt in the soil is harmful to both landscape and grass plants. Adding calcium, contained in Lawn Cal, will facilitate damaging salts to leach through the soil quickly while preventing salt uptake into the plant. Left untreated and allowed to be absorbed, toxic ice melting salts will interfere with the plant’s metabolism causing lethal and permanent damage. Also, this newly available calcium will promote the root uptake of beneficial nutrients.

How to Prevent Pet Urine Spots in the Yard
Pet and animal urine can leave behind unsightly dead spots in your lawn, usually found in areas where the dog or pets frequently urinate. To prevent pee spots in your yard, apply Lawn Cal at a rate of 40 lbs per 1,000 sq. ft. over the entire pet area in early spring and fall. Supplementing beneficial calcium into the soil will assist in the leaching of harmful elements contained in pet urine, facilitating their movement through the soil structure, away from grass roots, allowing the grass to stay green and healthy. Lawn Cal is a naturally occurring compound safe around kids and pets.
Uncle’s Tip: Water those pet areas frequently to assist in moving the harmful elements through the soil.
How to Repair Dog Urine Spots in the Yard
The first step in repairing pet urine spots in the yard is to apply Lawn Cal to the entire area and then water it in with a minimum of ½ inch of water. To repair pee spots in your yard, apply Lawn Cal at a rate of 40 lbs. per 1,000 sq. ft. The calcium contained in Lawn Cal will assist in leaching the damaging soil contaminates from the pet spots. Repair the bare spot by raking and removing any loose debris. Apply a thin layer of PrimeraFC over the bare area. Apply your preferred grass seed at the heavier bare soil rate. Cover the grass seed with an additional thin layer of PrimeraFC, then water, water, water.
