Benefits of Applying Gypsum as a Fertilizer

Gypsum is applied to the soil to improve soil conditions. Here are some benefits of applying gypsum as a fertilizer to your soil:

1.    A great Source of Calcium

Calcium is vital as it helps with plant growth, especially for roots and shoots support. Deficiency of calcium in your plant can cause weak stem, stagnant or dead buds, weak roots, dropping of flowers, and abnormal patches of fruit colors. Gypsum contains 21 percent calcium essential for your plant structure. Calcium provided by gypsum prevents end rot in tomato plants, watermelons, peanuts, and apples.

2.    More Efficient than Limestone

Gypsum is also preferably to limestone which some gardeners use as a calcium source. Limestone is not water-soluble like gypsum. Also, limestone might not get into the soil where it’s needed most. However, with water, gypsum will dissolve well into the soil and move quickly right where it’s needed.

3.    Does not Affect Soil pH

Gypsum does not have any effect on the pH of any soil. It is a natural mineral that neither adds nor removes minerals already existing in the soil.

4.    Excellent Source of Sulfur

Sulfur is a vital nutrient for protein synthesis in plants. Gypsum application ensures sulfur is provided to your soil. The sulfur in gypsum is readily available for immediate use. Unlike elemental sulfur which is unavailable to plants and requires soil bacteria to oxidize sulfur for availability.

5.    Amends Soil Compaction

Heavy clay soil is one big headache for farmers because of its tightly packed soil that can make work difficult. When gypsum is added to heavy clay soil, it will amend soil compaction and increase soil aeration. It will improve the soil structure increasing water porosity, nutrient penetration, and better root development.

6.    Amends Damages from Salt and Pet Urine

Coastal or arid areas where salt meets the melted snow during winter can cause damages to your garden crops or lawns. The good thing is adding gypsum to your soil will help neutralize the effect of this salt damages as well as repair them. Gypsum is also a good pet urine neutralizer.

Gypsum Application as a Fertilizer

Naturally occurring minerals are contained in gypsum which is vital for your crops to flourish. Be it vegetables, flowers, trees, shrubs, or turfs, gypsum application will work wonders on your garden or lawn. Gypsum is harmless, therefore, it’s safe for usage around humans, pets, and crops.

Gypsum comes in different forms such as granular, pelleted, and pulverized. The exact form of gypsum you may require will be based on the manner you decide to apply it to your garden or lawn.

Forms of Gypsum Fertilizer

Here are the various forms of gypsum:

  • Pelleted Gypsum: Pelleted gypsum is fast-acting. They have low dust formula which is easy to work with any fertilizer spreader.
  • Granular Gypsum: Granular gypsum is a slower release formula and low dust. Granular gypsum can be spread freely and easily and it works with any fertilizer spreader.
  • Pulverized Gypsum: Pulverized gypsum is a perfect form of gypsum that will deliver extended-release. It performs better in broadcast or drop-style spreader device for powder.

The quantity of gypsum you will require for your garden or lawn will solely depend on how you intend to use it: it will also depend on the status and conditions of your soil. This is why we suggest you perform soil analysis to be sure that the application of gypsum is favorable to your plants.

For instance, if the compacted clay soil in your area is high, you will require a bigger level of gypsum to give you the desired outcome and vice versa.

Also, ensure you water deeply the gypsum into your soil right where the gypsum is needed.

Should I use gypsum as a fertilizer?

Gypsum is an excellent fertilizer for most plants. It’s very rich in phosphorous, which is needed by all plants. The only drawback is that gypsum tends to be somewhat acidic and may make your soil too acid for certain plants. This can be mitigated with the use of lime, which should be applied in conjunction with gypsum. In fact, gypsum and lime are often used together as a soil-conditioning mixture.  Gypsum is pretty inert. Gypsum has been used for weed control for over a century and it works by creating a barrier to stop seedlings from emerging. It also discourages the growth of roots. You’ll find it used in many gardening books on how to control weeds in vegetable gardens. Gypsum is a common ingredient in fertilizers and if you do some research you’ll find that it’s used in many commercial fertilizers. I’ve been using it for years to control weeds in my garden and it really works well. The only thing you need to watch out for when using it is that it can make the soil too dry, but that shouldn’t be a problem since it’s mainly used as a mulch. Gypsum should be added to pots after you’ve watered them. If your soil is too wet you might want to add some dry material like vermiculite or perlite. These will help to dry out the soil and allow for more air circulation. 

Can you put gypsum around plants?

Gypsum is a mineral. You can’t put it around plants, because it’s too heavy for them to support. It can be sprayed on plants, but it is not a good insecticide.

Can you mix gypsum and fertilizer together?

Yes, it can cause problems. Mixing fertilizer and gypsum is not a good idea. It’s better to buy one or the other. Fertilizer alone does not have enough nutrients for the plants and gypsum is very slow to break down and release the nutrients. I think that you should use gypsum on your lawn first. You can use fertilizer as a top dressing after it has been applied to the lawn.

What are the benefits?

The benefits of using gypsum to improve your garden are numerous. It is inexpensive, easy to use, and has many other uses. It improves soil structure Gypsum adds strength to soil by creating a strong surface layer. This prevents water from soaking into the soil too deeply. In addition, the water that does get into the soil is more evenly distributed, which helps prevent erosion. This makes it easier for plants to absorb nutrients and water, making them grow healthier. It eliminates salt build-up When you apply gypsum to your soil, it will absorb any excess salt that is present in the soil.

Conclusion

With the above information, it’s safe to conclude that gypsum is a good fertilizer for your vegetables, trees, shrubs, flowers, and turfs. Gypsum is a harmless fertilizer and it will supply your plants with some beneficial nutrients to make your plant grow healthy.
