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 Using Lawn Cal
- Loosens compacted soils improving soil porosity
- 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 and oxygen penetration into and through the soil
- Enhances the value of the organic matter in the soil
- Amends waterlogged soil and lessens water puddling.
- 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.
Routine Repair for Dog Runs
Soil compaction makes it difficult for the grass to grow in the areas where Spot runs along your deck and fence. Compaction leaves little or no oxygen available to the roots. Reduce compaction with an application of Lawn Cal every spring and core aerating your lawn every fall. Pass over the lawn at least 2-3 times focusing on the heavy traffic areas.
PrimeraOne field conditioner should be applied after aerating the dog run and all compacted areas. Rake or sweep the chips into the core holes. The entire lawn will benefit as well, especially if you have poor drainage.
Sports Turf Perennial Rye for Heavy Traffic
Overseeding those areas with high traffic tolerant sports turf perennial rye grass such as Stadium Special, frequently throughout the season, will give support to your existing lawn and blend well with bluegrass or fescue. Stay ahead of the game and overseed with Macho Mix fescue or Estate Mix bluegrass each contain some perennial sports turf rye for traffic tolerance and quick germination.
Fertilize High Traffic Areas Regularly
Golf Course Starter or Renovator should be applied every four weeks in spring & fall growing season. Water your lawn regularly during the dry summer months. Watering in the morning is recommended to avoid turf fungus. A deep watering applied infrequently is best. Average watering should be one inch per week. Hot summers with excessive heat, may require up to two inches per week.
Are These Product Pet Friendly?
It is impossible to eliminate all risks inherently associated with any lawn products either organic or inorganic. There are hazards and cautions for sugar and table salt as well. We do recommend watering each product with at least ½ inch of water and letting the lawn dry before allowing pets access to be on the side of caution. And as always we recommend reading the entire label prior to any application and following all label recommendations. We’ve been doing this for 60 years and haven’t lost anyone yet.
