It is amazing how using pesticides, herbicides, and fertilizers has just become a normalized part of our Western culture. When did we decide that convenience should override health and that we need to control every piece of our environment including the plants and the bugs? Who was it that decided that having a perfectly manicured lawn was what everyone should have and that we should have plants that look pretty but would not naturally be part of our landscape?
If you look into why these processes have become normalized, it is puzzling why as human beings we have conformed and don’t question the process, especially when our health is at stake.
Whats the problem with using fertilizers in our yard?
As the use of synthetic fertilizers became more widespread, concerns about their environmental impact have emerged. Issues such as nutrient runoff leading to water pollution and soil degradation has become front and center for environmental health.
Here are a few good reasons NOT to use synthetic fertilizers in your yard.
-
Nutrient Runoff: Excess synthetic fertilizers can lead to nutrient runoff, where surplus nutrients wash off the soil and enter water bodies. This can cause eutrophication, a process where excessive nutrients lead to the overgrowth of algae, which depletes oxygen in the water and harms aquatic life.
-
Soil Health: Over-reliance on synthetic fertilizers can disrupt the natural microbial ecosystem in the soil. Healthy soil relies on a diverse community of microbes that help decompose organic matter and make nutrients available to plants. Synthetic fertilizers can reduce this microbial diversity and compromise soil health over time.
-
Water Contamination: Runoff from synthetic fertilizers can contaminate drinking water sources with nitrates and phosphates. High levels of nitrates in drinking water can be harmful, especially to infants, as it can interfere with oxygen transport in the blood.
-
Soil Acidification: Some synthetic fertilizers, particularly those containing ammonium-based nitrogen sources, can acidify the soil. Acidic soils can harm plant roots and reduce the availability of essential nutrients.
-
Reduced Soil Structure: Frequent use of synthetic fertilizers can degrade soil structure, leading to issues like reduced water infiltration and increased erosion. Good soil structure is crucial for healthy plant growth and water retention.
-
Greenhouse Gas Emissions: The production and use of synthetic fertilizers contribute to greenhouse gas emissions. For example, nitrogen fertilizers can release nitrous oxide, a potent greenhouse gas, into the atmosphere.
-
Dependency and Overuse: Synthetic fertilizers can lead to dependency, where plants rely on continuous external inputs for growth. This can result in overuse, where more fertilizer is applied than needed, exacerbating the issues.
-
Health Risks: Some synthetic fertilizers contain chemicals that can be harmful if not used properly. For example, excess phosphorus can lead to harmful algal blooms, which can produce toxins that pose health risks to humans and animals.
-
Impact on Beneficial Insects: Certain synthetic fertilizers can affect beneficial insects and organisms in the soil, such as earthworms, which are crucial for maintaining soil fertility and structure.
What are healthier alternatives to nitrate based fertilizers:
There are some simple solutions to these complex problems that nitrate fertilizers are causing. Here are a few actionable items that you can do at home.
Composting: Adding compost to your garden enriches the soil with nutrients and organic matter. You can make compost from kitchen scraps, yard waste, and other organic materials. Compost helps improve soil structure, water retention, and microbial activity.
Manure: Well-rotted manure from animals like cows, horses, or chickens can provide essential nutrients. It’s crucial to use aged manure to avoid burning plants with high nitrogen content.
Cover Crops: Planting cover crops, such as clover or legumes, can improve soil fertility. These plants fix nitrogen in the soil and, when tilled under, add organic matter and nutrients.
Green Manures: Similar to cover crops, green manures are plants grown specifically to be incorporated into the soil to enhance fertility. They often include legumes and other fast-growing plants.
Bone Meal and Blood Meal: Bone meal provides phosphorus, while blood meal offers nitrogen. Both are natural and can be used to supplement soil nutrients.
Fish Emulsion: This organic fertilizer is rich in nitrogen and other nutrients. It’s made from processed fish and can be a good option for boosting plant growth.
Seaweed and Kelp: Seaweed and kelp are excellent sources of trace minerals and growth hormones. They can be used as a liquid fertilizer or incorporated into the soil.
Worm Castings: Earthworm castings are highly nutritious and improve soil structure. They are rich in essential nutrients and beneficial microbes.
Mulching: Using organic mulches, like straw, leaves, or wood chips, can add nutrients to the soil as they decompose and help retain soil moisture.
Green Tea or Herbal Teas: Infusions made from comfrey, nettles, or other nutrient-rich plants can be used as natural fertilizers.
Pesticides, how did they become a thing?
The use of pesticides in yards and gardens became popular and normalized due to a combination of historical, economic, and social factors including access to the products along with increased marketing and advertising. Suburban sprawl played a part in why people are coming into more contact with insects and animals. Convenience and social acceptance has played a huge role as well, with the lack of awareness from consumers, and lack of regulations from our law makers.
In recent years, there has been a growing awareness of the potential risks associated with pesticide use, including health issues and environmental damage. This has led to increased interest in alternative pest management strategies and a shift towards more sustainable and eco-friendly practices in gardening and lawn care.
Using pesticides in our yards can pose dangers to human health, the environment, and ecosystems. Here’s a detailed look at these risks:
