What is Ferrous & Iron Sulphate for Lawns?

A lawn cannot grow healthy and strong by itself. Every lawn owner should implement specific techniques to take care of it. Gardeners have been using different fertilizer products on their lawns. The most common products contain potassium and nitrogen. If you already have such products, you should look for a fertilizer that has other valuable components such as copper, magnesium, choline, and iron.

Using it can help the lawn gain numerous benefits. You should know how to apply this chemical compound and avoid using too much on your lawn to avoid adverse effects. This compound comes with different label instructions that you should pay attention to. If you don’t understand the label, you should ask for guidance from a qualified horticulturalist before applying it on the lawn.

Why use iron sulfate on a lawn?

Ferrous sulphate heptahydrate can transform your lawn if you use it correctly. It has the following benefits on a lawn.

Pumping iron

Have you noticed some parts of your lawn turning sickly yellow? If yes, this should tell you that the lawn is lacking iron. This is a crucial mineral that plants need. When the plants in your lawn do not receive enough iron, they cannot grow properly. In humans, this mineral is important since it helps in the transportation of oxygen to the brain. Plants also need iron to produce chlorophyll.

Chlorophyll is crucial since it is responsible for the green coloration of plants. This component harnesses sunlight to create sugars. The plants in your lawn also need iron to produce hormones and enzymes that control the regular functions within the cells. A person that lacks enough iron in the body is considered anemic. When a lawn lacks iron, it is said to have a condition known as chlorosis.

This is what causes the yellowish color in the plant leaves. If your lawn is iron deficient, the leave blades can even be floppy. Malnutrition in a lawn makes it prone to diseases and pests. Using ferrous sulphate is essential in a lawn since it can give it the necessary amount of iron for the lawn to thrive. This compound contains about 19% of iron. Once you spray this organic compound on your lawn, you will soon notice a vibrant green color on the plants. The grass becomes silky soft, and every blade becomes tougher within no time.

Lawn fertilization

Though most of the regular fertilizers that some gardeners use on their lawns have nitrogen, high amounts of this substance can have some negative effects. Nitrogen-based fertilizers may promote the growth of small plants in a lawn, but too much of it can make it susceptible to pests and diseases.

Irrigation or rainwater can also leach nitrogen from the soil. When this compound makes its way into rivers and streams, it can lead to eutrophication. Instead of using nitrogen-based fertilizer, you should consider using sulfate of iron as an alternative. This fertilizer is excellent since it is more environmental-friendly compared to a nitrogen-based one. Apart from supporting plant functions, using iron sulphate on a lawn can also promote cold resistance.

Moss control

It reduces pests

Birds love looking for food on lawns. When the digging is too much, they can leave the lawn looking unattractive. You should consider using soluble iron on your lawn since this can help eliminate pests in it. Since the product is acidic, it can make the lawn less appealing to worms. This can also discourage birds from digging in the lawn looking for pests. The acidic nutrients in the sulfate of iron can also make the grass fine instead of spiky or rough. You can make the lawn totally pest-free by combining iron sulphate with a natural method like neem oil.

Soil acidification

Iron is not the only compound found in this product. The compound also contains oxidized sulfur. When you use it on a lawn, the soil microbes tend to break down different component minerals. During the breakdown, both iron and sulfur needed for photosynthesis are freed. A particular amount of sulfur finds its way into the soil, and it becomes sulphuric acid. If your lawn is on alkaline soil, the conversion process can lower its pH. You should avoid using too much of this substance since it can reduce the soil pH too much, which is unhealthy for the lawn.

Give it at least a minute after mixing, and then spray it on the lawn. Be careful when spraying it to avoid excessive staining.

Once you have done the spraying, some of it is absorbed through the plant leaves while some of it makes its way into the soil. If you are dealing with clay-based or acidic soil, the product will be locked into the soil,preventing the plants from absorbing it. Ensure that you spray this compound on the lawn when there is ground moisture to enhance absorption. You should avoid applying it in dry conditions since this can cause transient damage to the grass.You should also avoid using it in intense heat conditions.

You can use this substance at least two or three times on your lawn a year. Consider using it after scarification so that the grass can bounce back properly.
