Is Ammonium Sulfate Good For Lawns

UNBOXING DIY Tackle Making Goodies (Jigs, Plastics, & MORE)

Ammonium sulfate is a good lawn fertilizer because it contains nitrogen and sulfur that make the grass grow faster and turn greener. The 21% nitrogen content promotes a faster growth rate and helps the grass grow thicker. The sulfur content is also great if you want to lower the pH of the soil.

In instances of tired or dormant lawns, high soil pH , low density, thinner grasses, and yellowing turfgrasses, feeding the lawn with a good fertilizer such as Cesco Solutions Ammonium Sulfate will help fix the lawn.

Can I Put Ammonia On My Lawn

Ammonia is comprised of nitrogen, the stuff that lawns crave. Often applied as ammonium nitrate or urea, household ammonia can also be used to obtain the same results. Add 1 cup of ammonia to a 1-gallon container. Turn on the water, and apply the ammonia fertilizer to your entire lawn early in the morning. via

Why When And How To Use Ammonia Sulfate On Your Lawn:

  • It can help your grass fight off disease and insects
  • The added fertilization will encourage new root growth and build up its immunity
  • You can apply it anytime during the spring and summer months, but not during rainy weather since rain will break it down before it has a chance to do its job
  • There are two ways that homeowners typically apply it: by hand or with an automatic spreader
  • For both applications, follow the instructions on your container of ammonia sulfate for proper dosage rates based on your lawn size. If using a hose-end applicator or drop spreader, set them to use 1 gallon of water per 1 pound of ammonium sulfate
  • Homeowners typically add it to their existing lawn fertilizer for an extra boost of nitrogen and sulfur. For example, if your lawn fertilizer has a nitrogen analysis of 28-3-5 and you want the benefits of ammonia sulfate but also want more phosphorus, mix 1/2-pound of ammonium sulfate into every 50 pounds of your existing lawn fertilizer to achieve a total nitrogen content of 25 percent and a phosphorus content of 0.5 percent, according to University of California IPM.

Applying Ammonium Sulfate Fertilizer

Apply ammonium sulfate in the late spring or late summer. Avoid using it in the late fall to prevent a flush of growth that can increase the likelihood of winter kill and diseases. After an application, it should provide for adequate growth through several mowings. Apply ammonium sulfate in 45- to 60-day intervals.

You can spread granules of ammonium sulfate with a drop or broadcast spreader. If using liquid spray ammonium sulfate, dissolve up to 3 tablespoons of fertilizer per gallon of water. Use it to water the plants deficient in nitrogen and sulfur. Be careful not to overapply it and spray only when its cool and cloudy outside. When combined with direct sunlight, it can damage your plants. Water thoroughly after applying.

Use only as much ammonium sulfate as needed. Remember: Less is more! Too much ammonium sulfate can burn the grass. In fact, a higher likelihood of burning exists with ammonium sulfate than with any other slow-release product. If applied in excess, it also can leach from the areas in which you’ve applied it. Monitor the soil pH carefully both before and after applying fertilizer.


Ammonium Sulphate For Lawns Yes Or No

Ammonium Sulphate or Sulphate of Ammonium can create a green lawn faster than most other products but it comes with a warning. Before using Ammonium Sulphate you should carefully consider the drawbacks. Essentially Ammonium Sulphate is straight Nitrogen, a main element in lawns and the N in the NPK ratio often displayed on fertilising products. Being the primary nutrient responsible for green leaf growth, Nitrogen applied on its own will quickly increase green leaf growth but the drawback is that it will not support any other normal developmental processes that your lawn requires. Ammonium Sulphate applications will supercharge the green leaf growth, but at what cost to the long term health of the lawn?

Rapid leaf growth leads to the potential that your lawn will become scalped after the next mowing or even the next few mowings. Scalping, in turn, can lead to overall poor health which encourages pest infestation, weed infestation and disease. Your lawn can also struggle to self-repair and can even die if the soil dries out too quickly. Additionally, if the crowns of the lawn raise too high during the leaf growth process and are then removed during lawn mowing, that section of lawn is likely to die.

Jun Ammonium Sulfate As A Lawn Fertilizer

Ammonium sulfate is a water soluble fertilizer providing 21 percent nitrogen by weight and 24 percent sulfur. The guaranteed analysis is 21-0-0+24. It can be applied to lawns as a top dressing of nitrogen and sulfur with a broadcast or drop-type spreader. In areas with high pH soils, the sulfur in ammonium sulfate helps lower soil pH levels. As with other fertilizers, water the treated area well after each application.

EffectsAmmonium sulfate provides lawns with readily available nitrogen and sulfur. It helps lawns green up quickly, helps in cold soils, and is relatively inexpensive. If too much ammonium sulfate is applied, an undesirable large amount of growth may result. Grass is more likely to be burned with applications of ammonium sulfate than with slow release products, and there is a greater likelihood of it leaching off the places where it is applied. When using ammonium sulfate, monitor soil pH and add lime as needed.

BenefitsAmmonium sulfate has several benefits in addition to providing quick grass growth and reducing soil pH levels in alkaline lawns. It is easy to store and does not melt in high humidity like ammonium nitrate, another high nitrogen fertilizer. It is produced domestically as a by-product of the steel-making industry and is not subject to price fluctuations of natural gas, a chief component in anhydrous ammonia used to make ammonium nitrate. Ammonium sulfate is also nonflammable.


Ammonium Sulfate Fertilizer Advantages And Disadvantages

Before you apply it, first consider ammonium sulfate fertilizer’s advantages and disadvantages. Its benefits typically outweigh the challenges. It encourages rapid grass growth and quickly reduces soil pH in an alkaline lawn. Not only that, but this fertilizer is easy to store and apply. Unlike other high-nitrogen fertilizers, such as ammonium nitrate, it doesn’t melt when exposed to high humidity conditions.

This fertilizer is also cost-effective since it’s produced in the United States as a byproduct of manufacturing. Moreover, it’s not subject to the price fluctuations typical for natural gas that occurs during ammonium nitrate production. Its non-flammable and safe to use in most cases.

However, as with any fertilizer, first test the soil prior to amending so you will know whether it needs additional nitrogen. Nitrogen can burn a lawn when applied at an excessive rate. In general, you should apply no more than 1 pound of nitrogen for every 1,000 square feet. If you’re growing a low-maintenance type of grass, your rate of application will run even lower.

Also note that this fertilizer can be toxic in large amounts. Avoid ingestion and prolonged contact with the skin. It should be kept out of waterways since it can promote algae growth.

How To Kill Moss With Sulfate Of Ammonia

Moss grows in lawns for several reasons, including poor soil drainage, excessive watering, inadequate fertilizer or lack of sun. Moss can also make these problems worse. A well-maintained lawn with healthy growing grass can reduce the growth of moss, and an application of sulfate of ammonia, also called ammonium sulfate, boosts the growth of the lawn by supplying nitrogen. When healthy grass fills in bare spots, it makes growing conditions unfavorable for moss.

  • 1.

    Rake away any leaves or debris from the mossy areas of the lawn.

  • 2.

    Fill a broadcast or drop spreader with 5 pounds of ammonium sulfate granules for each 1,000 square feet of lawn area. Set the spreader to apply 1 pound of ammonia sulfate per 200 square feet. Settings vary depending on the spreader brand and model.

  • 3.

    Walk the spreader evenly over the mossy areas of the lawn to broadcast the fertilizer evenly.

  • 4.

    Water the lawn deeply with a garden hose or sprinkler to help the ammonium sulfate soak in.

  • 5.

    Rake out any dead moss from the lawn when it turns black.

  • References


    • Wear gloves and protective eyewear to prevent contact with the ammonium sulfate granules. Wash your hands after use.
    • Keep to the recommended rates of ammonium sulfate because it can burn your lawn if you apply too much.
    • Keep ammonium sulfate out of the reach of children and pets.

    Can I Add Ammonium Sulfate To The Lawn All Summer

    Corn Response to Sulfur in Indiana


    I was very interested in a recent article about adding ammonium sulfate to one’s lawn to keep it green. Can I do this all summer long, every 8 weeks?

    Answer: The short answer is yes. Once a year use a high-quality lawn fertilizer as one of the applications. The best lawn fertilizers have a ratio of nitrogen to phosphorus to potassium of 3-1-2 or 4-1-2 with most of the nitrogen available as slow release. One example would be 21-7-14. There are many others.

    The principle nutrient lawns need is nitrogen on a regular basis. Nitrogen fertilizers keep lawns green and lush. Nitrogen is the first number in the triad of numbers on the fertilizer bag.

    In the case of ammonium sulfate this is 2100. A bag of ammonium sulfate contains nitrogen, hydrogen, sulfur and oxygen in mineral form. There is no filler in it. Ammonium sulfate is 21 percent nitrogen. The usual recommendation for lawns is 1 pound of nitrogen every 1000 square feet.

    This is applied with some sort of spreader such as a drop spreader, a broadcast spreader or hose end applicator. Since ammonium sulfate is 21 percent nitrogen, then 5 pounds of 21-0-0 delivers about 1 pound of nitrogen.

    However, I find this rate is higher than necessary and lawns do just fine at half to three quarters of this rate. This is particularly true if mowing with a mulching mower and the clippings are allowed to fall back on the lawn. Lawn clippings are very high in nitrogen and act like an extra fertilizer application.

    Will Ammonium Sulfate Burn My Lawn

    Too much ammonium sulfate can burn the grass. In fact, a higher likelihood of burning exists with ammonium sulfate than with any other slow-release product. If applied in excess, it also can leach from the areas in which you’ve applied it. Monitor the soil pH carefully both before and after applying fertilizer. via

    What Is Ammonium Sulfate Fertilizer

    Ammonium sulfate provides roughly 21 percent of nitrogen and 24 percent of sulfur, with a guaranteed 21-0-0 content. Apply it to lawns as a top dressing with a drop or broadcast spreader. Because it contains sulfur, it can also help lower soil pH levels, according to Cornell University.

    Produced for more than a century, ammonium sulfate fertilizer originally was made from the ammonia released during the manufacturing of coal gas and coal coke to make steel. Today, it’s usually made through a reaction of sulfuric acid with ammonia. White to beige in color, it’s most often sold as a water-soluble crystal. It’s typically used to supplement the nitrogen and sulfur needs of growing plants, according to Michigan State University. This fertilizer is best used on grass types with high nitrogen requirements, such as Bermudagrass . It’s usually applied during high-demand seasons like late summer or spring.

    When To Use Ammonium Sulfate Fertilizer

    The best time to apply ammonium sulfate fertilizer for cold season grasses is late summer to early fall. For warm-season grasses, apply ammonium sulfate fertilizer in the spring and fall.

    Applying ammonium sulfate on cold season grasses during summer to early fall enables them to recover from summer. The grasses become greener, their shoot density increases, and it prepares them for the winter season. For cold season grasses, avoid applying any fertilizer during winter because most grasses become dormant in winter.

    For warm-season grasses, apply ammonium sulfate fertilizer in spring and fall for the best results. Use the fertilizer six weeks before the onset of the first frost.

    What Is The Best Way To Use Ammonia Sulfate

    So what is the correct way to use it? The easiest way to apply ammonia sulfate is by using granules. Apply them in early spring before your grass starts to green up.

    Make sure you water the lawn heavily right after applying this fertilizer to get the ammonium ions into the soil where they can be taken up. You should see a change within a week or so if applied correctly happy grass!

    As winter approaches, repeat your application because your grass must have plenty of nutrients going into winter for storage.

    Ammonia Sulfate As A Fall Or Winter Treatment

    When used in autumn or winter, ammonium sulfate can help thicken the grass blades and crust over the soil to prevent water loss, according to the University of Minnesota Extension.

    It does this because it takes magnesium out of the soil to form this crusting effect, so be sure your lawn has sufficient supply before applying any during fall months. Because ammonia sulfate is highly soluble in water, the rain will break down any treatments you apply before they get a chance to do their job so applying during rain isnt recommended.

    The best time for fall treatment is just before planting sod or seeding new grass into an area thats been covered with an impervious ground cover such as brick, asphalt, or stone.

    If you only do one lawn treatment per year, ammonia sulfate fertilizer might be the right choice for you. It can help your grass fight off disease and insects. The added fertilization will encourage new root growth and build up its immunity.

    You can apply it anytime during the spring and summer months, according to the University of California Integrated Pest Management . There are two ways that homeowners typically apply it: by hand or with an automatic spreader.

    For both applications, follow the instructions on your container of ammonia sulfate for proper dosage rates based on your lawn size. If using a hose-end applicator or drop spreader, set them to use 1 gallon of water per 1 pound of ammonium sulfate.

    Nitrogen And Sulfur Benefits

    Ammonium sulfate supplies lawns with nitrogen and sulfur. Nitrogen is a major grass nutrient used to create chlorophyll, which grass needs to live and grow, and sulfur is a secondary nutrient. Soils low in organic matter may lack sulfur, which causes yellowing older leaves, slow growth, and delayed maturity in grass. Ammonium sulfate supplies nitrogen and sulfur in a water-soluble form, so that as soon as it rains or the lawn is irrigated, nutrients are immediately available to grass roots. Ammonium sulfate is cheaper than slow-release fertilizers per pound of nitrogen and produces a rapid greening effect even at low temperatures.

    How Long Does Ammonium Sulfate Last

    Now the most asking query is that how long does it take time to work and how long does it last?

    Let me explain!

    When you apply ammonia sulfate on your lawn, dont show hurry. You may have to be patient after the application in about 12 to 24 hours. This condition is preferable in hot areas or climates. Dont water heavily the soil right after fertilizing the lawn. This will nurn the weeds and watering the soil continues to burn off the clover.

    There is no need to apply ammonium sulfate again and again as it lasts 4 to 6 weeks. It will work only if you choose 5 pounds of fertilizer 1000 per sq. feet. or 200 pounds per acre.

    Another important point you have to know is that it has a shelf life of 6 months from the production date. Keep it sealed and away from children and pets. To get the best results for a long time, apply it only on dry grass. Later you can water your lawn thoroughly.

    It is a quick-release formula that helps your lawn to become green and fresh. Add ammonium sulfate fertilizer slowly on your lawn to make sure that the local concentration does not exceed the desired salt concentration. So, be careful.
