Some homeowners might ask, “Why do we have to be responsible in our use of fertilizer?” Apart from helping reduce carbon emissions, responsible fertilization also helps protect soil and human health.

If you’re responsible when using fertilizers, not only are you supplying your lawn with vital nutrients and promoting grass growth, but you’re also taking small steps to help resolve some of the environmental issues we’re dealing with — including global warming.

Fertilizers help us achieve the optimal production of food. They have revolutionized our agriculture by increasing crop yields and reducing the percentage of land needed for farming. Plus, they help boost food production to more than match the needs and wants of our growing population.

However, it’s one of the advancements that’s getting blamed these days when it comes to environmental issues. But if we think about it, fertilizers are only as bad as we allow them to be. It all depends on proper usage, especially for homeowners who are not under the pressure of meeting agricultural production demands.

Since we only apply fertilizers in our lawns and gardens, it’s easy for us to take extra care when using them. And if we are responsible when using fertilizers, we can enjoy many benefits, including:

Preservation of ecosystem

A lush lawn can help preserve the ecosystem, even if it’s just within its area of influence. And if we use the right type, amount, and combination of fertilizers to maintain our lawns, we’re reducing carbon pollution and cooling the environment. With this bit of change, we can do our part to improve the air quality and preserve the biosphere in our communities.

One study suggests that landscape plants, including shrubs, vines, and trees, can help save up to 25% of the energy costs a typical household consumes. The drop in temperature usually ranges between 7 and 14 degrees, which helps lower the cost of air conditioning during summer.

Soil health maintenance

Plant leaves, stems, and roots shed as part of their annual growth cycle. Over time, this process adds vast amounts of organic matter to the soil. This organic matter serves as a natural fertilizer that helps improve the soil structure necessary for maintaining healthy gardens and lawns.

It might be tempting to saturate the soil with all kinds of fertilizers to help speed up plant and grass growth. But if we over-fertilize the soil, plants will be unable to absorb all these nutrients, and our efforts will be in vain.

That’s why it’s crucial to do a soil test first, so we can follow the recommendations for choosing the correct type of fertilizer and applying just the right amount. Doing so can help our grass and plants consume all the soil nutrients and improve their root systems.

Protection of human health

When we apply fertilizers containing synthetic chemicals irresponsibly, they can leach into groundwater or other water bodies nearby. This fertilizer runoff can contaminate drinking water sources and cause serious health issues to people who consume the contaminated water.

Some of the adverse health effects of consuming contaminated water include:

  • Reproductive or nervous system diseases
  • Chronic illnesses like cancer
  • Gastrointestinal issues
  • Organ damage

Additionally, spraying chemical fertilizers can contribute to air pollution, which may exacerbate respiratory problems or trigger allergies in sensitive individuals. Responsible application of lawn fertilizers can reduce the risk of exposure to harmful chemicals and pollutants.

According to Alex J. Lindsey, assistant professor of the Department of Environmental Horticulture at the University of Florida, an urban landscape thrives with a healthy lawn. Beyond increasing property value, well-maintained lawns help cool the surrounding air, filter stormwater runoff, combat soil erosion, and buffer against glare and noise pollution.

Pro tip: If you have pets, choose a pet-friendly lawn fertilizer. Most homeowners who want to prioritize their pets’ well-being choose organic fertilizers formulated with natural ingredients and non-toxic compounds.

Whether you’re using organic or inorganic fertilizers, if you want your fertilization practices to be environmentally safe, you must apply them responsibly. Here are some tips to guide you:

  1. Choose the right fertilizer: Select fertilizers as recommended in your soil test results. It would depend on factors like grass type, soil type and quality, and nutrient requirements.
  2. Follow instructions: The fertilizer label is there for a reason. It usually indicates recommended application rates, timing, and safety precautions. So, carefully read and follow the manufacturer’s instructions on the packaging.
  3. Use proper application techniques: Choose the appropriate application method for your lawn. Most homeowners use a broadcast spreader, handheld spreader, sprayer, or drop spreader. Apply the fertilizer consistently to get even coverage.
  4. Don’t apply in areas with natural drainage: These locations can allow fertilizers to combine directly with surface water, which can lead to water contamination and pollution.
  5. Avoid over-fertilization: Applying too much fertilizer can cause plant damage, nutrient runoff, and water pollution. Soil test results indicate the amount of nutrients in the soil, so you should be able to compute the specific amount to use.
  6. Observe the best time to fertilize your lawn: When applying fertilizers, proper timing is crucial to ensure grasses receive the necessary nutrients at the right time. Also, avoid fertilizing your lawn before heavy rains or during periods of drought to prevent nutrient runoff or leaching.
  7. Clean up spills immediately: In the event of spills, don’t wash them into the street. Also, when cleaning your liquid fertilizer applicator or granular fertilizer spreaders, do so over grassy areas to prevent runoff to hard surfaces.

Note: Remember to store or dispose of the fertilizer properly after using it. Keep it away from children and pets, and store it in an airtight container to prevent moisture or spills. If you’re throwing away unused or expired fertilizers, check your local regulations for proper disposal.

Alternative fertilizer solutions

Being a responsible homeowner doesn’t necessarily translate to going entirely organic when fertilizing the lawn. You can still select and use inorganic fertilizers as long as you know how to apply them responsibly. But if you would rather be environmentally friendly, then using an organic fertilizer is the way to go.

If you prefer to make an organic fertilizer yourself, there are some DIY homemade solutions for fertilizers. The examples below are not nearly exhaustive but will give you a quick overview of different homemade fertilizers you can make:

  • Household ammonia
  • Coffee grounds
  • Composting
  • Epsom salt
  • Mulching

Although these alternative solutions may seem chemical-free, some also can pose risks. For instance, if large amounts of ammonia get washed off by rainwater into a nearby body of water, it can kill fish and other aquatic life. Additionally, pet owners should avoid using coffee grounds, as they can be toxic to dogs and cats.

FAQ about responsible use of fertilizers

How do fertilizers contribute to lawn health?

Fertilizers are indispensable not only when reviving a dull and dying lawn but also for regular lawn care maintenance. This is because fertilizers help provide the nutrients that grasses need, which are not always available due to various circumstances.

Here are some of the benefits of lawn fertilization:

  • Supplies vital macronutrients: Nitrogen makes the grass greener and phosphorus aids in plant respiration. Additionally, potassium helps lawns withstand extreme conditions, which is why it’s one of the main ingredients of late summer lawn fertilizers.
  • Promotes grass growth: Fertilizers can provide your lawn with micronutrients, such as chlorine, zinc, and iron, that help promote vigorous grass growth.
  • Boosts root development: Adding fertilizers can assist your lawn in developing stronger and deeper root systems.
  • Improves resistance to diseases: Fertilizers can make your lawn more resistant to various diseases and pest infestations.
  • Aids in faster recovery from damage: Fertilizing your lawn can help it quickly recover from wear.

Why is fertilizer use an issue?

Nitrogen and phosphorus runoffs are some of the biggest sources of coastal pollution, now referred to as “dead zones.” While the issue came from the irresponsible use of agricultural fertilizers, lawn fertilizers somehow got a bad reputation as well. After all, they’re still fertilizers.

What would happen if we entirely stopped using fertilizer?

Stopping the use of fertilizers completely may be feasible, but it would make it extremely hard to cope with feeding the growing population. While we can resort to using manure instead, it’s not an efficient solution, as we’ll need to have more animals that can produce enough manure.

Even in lawns, where soil nutrients get depleted every few months, stopping the use of fertilizers altogether is not a good idea.

How do fertilizers contribute to climate change?

Nitrogen-rich fertilizers produce nitrous oxide when they interact with microbes in the soil. When released into the air, it can be 300 times more potent than carbon dioxide in warming the atmosphere. This is another reason why it’s always important to follow recommendations from your soil test and avoid overfertilization.

Be responsible in applying lawn fertilizers

While fertilizers can help produce greener lawns, they also can be a source of environmental damage if used improperly. Being responsible means using fertilizer effectively without the risk of causing harm.
