Gypsum Improves Soil Structure

What is Gypsum and How Does It Help My Lawn and Garden?

Gypsum provides calcium which is needed to flocculate clays in acid and alkaline soil . It is the process in which many individual small clay particles are bound together to give much fewer but larger particles. Such flocculation is needed to give favorable soil structure for root growth and air and water movement.

What Does Gypsum Do For Soil

Improving soil structure helps farmers with some common agricultural problems. Adding gypsum to the soil reduces erosion by increasing the ability of soil to soak up water after precipitation, thus reducing runoff. Gypsum application also improves soil aeration and water percolation through the soil profile.

Gypsum Has A Higher Content Of Sulfur And Calcium

It is a good source of both sulfur and calcium, both of which are necessary for healthy lawn growth. With time you will notice your lawn grass looking weak and pale. This is usually due to your soil losing sulfur and calcium, which are vital for your soil nutrition and grass growth.

Proper application of gypsum can be all your lawn needs to spring back to life .both sulfur and calcium work by releasing unavailable nutrients to your lawn soil, allowing the grassroots to ingest them.

Plus, calcium also speeds up the growth rate of grassroots, thus enabling grass to suck up more nutrients.

Gypsum Can Remedy Lawn Damage

As grass emerges after winter, your lawn may not look quite as perfect as you remember!

During cold, snowy winters, lawns take a beating. All that snow, ice and sleet does damage especially if you live in a colder region where salt is spread to melt ice.

And, pets dont like the cold winter either! Often, they go to the bathroom in the same spot, so they can dash back inside as quickly as possible.

Both winter salt and pet urine cause ugly, patchy spots in the lawn.

But dont despair. All your lawn needs to recover is a little help from its friend, Espomas Garden Gypsum.

How do you know if gypsum is right for your lawn and garden?

If you see unsightly yellow or brown spots in the lawn, thats a burn spot that gypsum can restore.

Take a close look at the grass around walkways, sidewalks, roads and driveways. These areas are most likely where you or your county applied winter salt to melt ice. Salt draws moisture from grass roots causing it to turn brown.

Also, check areas where your pets frequently go to the bathroom for damage.

Then, transform those ugly brown spots into lush, green lawn by amending the soil with gypsum.

Gypsum works to replace the salt, heal the grass and encourage new growth. Add all-natural gypsum now and as needed as lawn burns appear throughout the season.

Simply use a drop or broadcast spreader to apply to damage spots in your lawn or garden. No need to work it into the soil.

Gypsum Improves Compacted Soil

How to Use Gypsum on Lawns

Gypsum can help break up compacted soil and decrease penetrometer resistance . Soil compaction can be prevented by not plowing or driving machinery on soil when it is too wet. The compaction in many but not all soils can be decreased with gypsum, especially when combined with deep tillage to break up the compaction. Combination with organic amendments also helps, especially in preventing return of the compaction.

Can You Put Too Much Gypsum On Lawn

One application will be sufficient for three years, and it can be applied at any time of the year. No worries, as gypsum is neutral and not toxic to animals and humans. If you are planning to plant vegetables, shrubs, and flowers, then mix well 20 to 30 pounds of gypsum per thousand square feet into the soil and water.

Is It Necessary To Apply Gypsum

Before you choose to apply gypsum in your garden, a soil analysis must be done to determine if it is really necessary to apply gypsum to your soil. Also, you must consider the type of soil you have in your garden. For instance, those living in coastal areas might need to apply gypsum to reduce the salt levels of their soil while those who have sandy soils must not do so to avoid excess calcium accumulation. Furthermore, in places where there are already low levels of sodium, applying gypsum may also deprive the soil of salt.

Improve Water Penetration In Your Lawn

If your lawn happens to have dense clay soil or compact soil, water might be having a hard time penetrating deep enough to the root zone. Poor water absorption may lead to stagnant water, which can exacerbate root diseases and nutritional deficiencies over time.

Adding gypsum to your lawn soil will improve water absorption and increase sodium levels, thus enabling water to seep through the soil, allowing your grass to thrive.

This also increases the chances of grass surviving even in dry seasons by improving the soil structural components that allow favorable soil-water interactions.

Gypsum Improves Fruit Quality And Prevents Some Plant Diseases

Calcium is nearly always only marginally sufficient and often deficient in developing fruits . Good fruit quality requires an adequate amount of calcium. Calcium moves very slowly, if at all, from one plant part to another and fruits at the end of the transport system get too little. Calcium must be constantly available to the roots. In very high pH soils, calcium is not available enough therefore, gypsum helps. Gypsum is used for peanuts, which develop below ground, to keep them disease free. Gypsum helps prevent blossom-end root of watermelon and tomatoes and bitter pit in apples. Gypsum is preferred over lime for potatoes grown in acid soils so that scab may be controlled. Root rot of avocado trees caused by Phytophthora is partially corrected by gypsum and organics .

Helps In The Reduction Of Phosphorous Losses

The other reason you need to put gypsum on your lawn is to help in soil erosion and reduce phosphorous losses. Different studies have demonstrated that using gypsum in your lawn will help in the retention of phosphorous and other soil nutrients.

Landscapers and other lawn specialists believe using gypsum as a soil enhancer is the most cost-effective approach in reducing soil phosphorous emissions and losses.

it is regarded as the best lawn management approach for lowering soluble phosphorous losses!

Gypsum As An Agricultural Product

The calcium and sulfur composition of gypsum makes it a very useful agricultural product. As a result, the chemical composition of gypsum makes certain nutrients more available to plants as compared to other fertilizers.

It should be noted that gypsum can moderately alter soil pH levels, but it also helps the roots develop faster, particularly in soils with an acidic nature. This is because gypsum counters the toxic impact of aluminum on root growth and development. Though aluminum is not hazardous for crops when the soil has a high concentration of acid, the aluminum present in the soil can harm or even kill the plants in the long run.

Gypsum Prevents Crusting Of Soil And Aids Seed Emergence

How to Use Gypsum on Lawns (with Pictures)

Gypsum can decrease and prevent the crust formation on soil surfaces which result from rain drops or from sprinkler irrigation on unstable soil . It can even prevent crusting that results when acid soils are limed , the gypsum is coapplied with the lime. The gypsum is either surface applied or put on in the irrigation system. Prevention of crust formation means more seed emergence, more rapid seed emergence, and easily a few days sooner to harvest and market. Seed emergence has been increased often by 50 to 100 percent. The prevention of crusting in dispersive soils is a flocculation reaction.

Gypsum For Salt Plant Damage

For the same reasons stated above, salt will also damage the plants in your landscape. Although not as common as salt in your lawn, rock salt ending up in your planting beds will still change the Ph of the bed soils and block the landscape plants from absorbing water. When this happens, evergreens with start to wilt, discolor, and die off. Deciduous plants will show visible signs as well, usually looking like burnt leaves. Using Gypsum around the base of your landscape plants is also a valuable ability of Gypsum.

So Where Does Lime Fit In

Lime is still a product we will use because of its benefits in increasing a soils pH and keeping lawns healthy. Where a soil test has been done or on a site where we know the ph is going to be too low we will use lime. Indications that the soil is acidic would be

  • Moss growing in full sun areas
  • The weed red sorrel is an indicator of low pH
  • Subdivisions that were previously blueberry fields or are near them may have a low pH level.

The AAA Lawn Care lime/gypsum applications will reinvigorate your lawn with the lime working to increase pH, and the gypsum adding high levels of calcium and sulfur. The combination of both the lime and gypsum leaves your lawn filled with nutrients and improved soil structure.

Is Gypsum Good For The Soil

Now that we have ascertained what gypsum is, its natural to question, Is gypsum good for the soil? Since it reduces salt levels in soil, it is effective in coastal and arid regions. However, it doesnt work in sandy soils and it can deposit an excess of calcium in regions where the mineral is already abundant.

Additionally, in areas with low salinity, it pulls out too much sodium, leaving the location deficient in salt. Considering the cost of a few bags of the mineral, using gypsum for garden tilth is uneconomical.

Gypsum Decreased Dust Erosion

What is Gypsum and how to apply it.

Use of gypsum can decrease wind and water erosion of soil . Severe dust problems can be decreased, especially when combined with use of water-soluble polymers. Less pesticide and nutrient residues will escape for the surface of land to reach lakes and rivers when appropriated amendments are used to stabilize the soil. Gypsum has several environmental values.

Gypsum Can Be A Source Of Oxygen For Plants

The sulfate that is taken up by plants and metabolized releases the associated oxygen which is a source of oxygen to plant roots although a limited source. Nitrate nitrogen does the same except it is a larger source of oxygen than is sulfate. Under adverse conditions, the oxygen coming from the sulfate can be important such as with root rot in avocado.

Are Gypsum And Lime The Same Thing

Both gypsum and lime are helpful soil amendments and can be used as calcium fertilizer suppliers. However, they serve a different purpose so they are not the same thing.

Lime can be used to elevate soil pH as it is more alkaline. On the other hand, gypsum cant be used to increase soil pH therefore it neutral and does not have any effect on soil pH. Gypsum is also a lot more soluble than lime. Gypsum as well is a great element applied to lawns that are close to the arid or salty region to stay protected from excess salt during winter.

The lime compound can consist of oxide, carbonate, or hydroxide of calcium, while gypsum consists of calcium sulfate.

Also, gypsum and lime can both increase water porosity. But water porosity decreases with lime as pH increases: whereas with gypsum, water porosity can be improved at any pH.

Subsequently, question is, what does Gypsum do for the soil? Gypsum is calcium sulfate, a naturally occurring mineral. It has been touted as beneficial for breaking up compact soil, especially clay soil. 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.

Beside above, when should I apply gypsum to my lawn?

Since Gypsum can be used on any soil type because it does not alter the soil pH level, you don’t have to balance your pH level before applying. Also, since Gypsum is not a fertilizer, it can be used before or after a fertilizer application, anytime of the season.

When should you apply gypsum?

Worry about the lime first. If your pH is good, and your lawn is still low in calcium and high in magnesium, then adding gypsum would be beneficial. Suface applications won’t do a whole lot, so apply it at when core aerating or tilling 40 to 50 lbs./ 1000.

How Much Gypsum Should Be Used

Applying too much gypsum to your garden soil can be problematic. To minimize any problems, you should first establish if your soil will benefit from any addition, and you should carefully follow any pack instructions.

Doing a soil analysis will establish how much calcium and sulfur are already present.

Gypsum Decreased Ph Of Sodic Soils

Gypsum immediately decreases the pH of sodic soils or near sodic soils from values often over 9 but usually over 8 to values of from 7.5 to 7.8. These values are in the range of acceptability for growth of most crop plants. Probably more than one mechanism is involved. According to Lindsay , Ca++ reacts with bicarbonate to precipitate CaCO_3 and release protons which lessens the hydrolysis of clay to form hydroxides. These reactions can decrease the incidence of lime-and bicarbonate-induced iron deficiency.
