Florida Fertilizer Laws: Homeowner Compliance Requirements

Florida's fertilizer laws are aimed at improving water quality and lessening runoff during the state's rainy season. Many counties have implemented fertilizer bans, prohibiting the application of any fertilizers containing nitrogen or phosphorus between June 1 and September 30, or when heavy rain is predicted within 24 hours. These restrictions apply to turfgrass and landscape plants, while edible crops are usually exempt. Homeowners should check their local municipality's fertilizer ordinance before fertilizing their plants.

Homeowners should be aware of local ordinances that restrict the use of certain fertilisers at specific times of the year

Homeowners in Florida should be aware of local ordinances that restrict the use of certain fertilisers at specific times of the year. These ordinances are in place to reduce the amount of fertiliser that ends up in the water supply, as this can cause algae blooms that deplete oxygen levels and kill fish.

Many Florida counties have implemented fertiliser bans that prohibit the application of any fertilisers containing nitrogen or phosphorus between June 1 and September 30. This is the rainy season in Florida, and the heavy rainfall can cause fertiliser to wash into watersheds, rivers, lakes, and oceans. The concern is that the summer storms will exacerbate the effect of fertiliser runoff.

There are some exemptions to these restrictions. Golf courses are often exempt, as are property owners who can demonstrate a phosphorous deficiency in their landscape. If you think you may fall into this category, you should conduct a soil test to confirm the deficiency and produce the necessary documentation for local authorities.

During the times of the year when fertiliser use is permitted, there are still some restrictions in place. For example, no more than four pounds of nitrogen per 1,000 square feet per year can be applied, and granular fertilisers containing nitrogen must be at least 50% slow-release nitrogen. Phosphorus is not allowed unless a soil test documents a deficiency.

It is also important to note that fertiliser should not be applied within 10 feet of a wetland or water body, and that nitrogen should not be applied to any newly installed plants for the first 30 days.

By following these local ordinances and restrictions, homeowners can help to protect water quality and the environment while still maintaining healthy landscapes.

Fertiliser ordinances aim to reduce runoff and improve water quality during Florida's rainy season

Florida's rainy season sees local governments implement ordinances to reduce the application of lawn fertilisers, with the goal of minimising nutrient pollution in the state's waterways. These ordinances are designed to reduce the occurrence of harmful algae blooms, which can have detrimental effects on marine life and the local economy.

Impact of Fertiliser on Waterways

Fertilisers are a type of nutrient pollution that can damage waterways. They act as food for vegetation in these ecosystems, and during the rainy season, they are often washed from lawns into bodies of water before plants can absorb them. This excess fertiliser can lead to algae blooms, which reduce oxygen levels in the water, creating "dead zones" where marine life cannot survive.

Ordinances to Reduce Runoff

To address this issue, many local governments in Florida have implemented ordinances prohibiting the use of lawn fertilisers during the rainy season. For example, Lee County's ordinance, passed in 2008, prohibits the application of lawn fertilisers containing nitrogen or phosphorus from June 1 to the beginning of November. Similar ordinances have been adopted by municipalities in Southwest Florida, including Cape Coral, Fort Myers, and Naples.

Improving Water Quality

The goal of these ordinances is to reduce the amount of nutrients, specifically nitrogen and phosphorus, that enter the area's waters. By doing so, they aim to decrease the occurrence of harmful algae blooms, which have had severe impacts in recent years. In addition to protecting marine life, improving water quality can have economic benefits, as it can enhance property values and improve the experience of visitors to the area.

Community Education

While these ordinances are an important step, education is also key to reducing nutrient pollution. It is essential that residents understand the connection between their fertiliser use and its impact on the environment. This includes knowing about the ordinances and following the guidelines they set out. By combining ordinances with community education, Florida aims to reduce runoff and improve water quality during the rainy season.

Homeowners should be aware of the risk of runoff washing into watersheds, which can have detrimental effects on the environment

Homeowners in Florida should be aware of the risk of runoff washing into watersheds, which can have detrimental effects on the environment. This is especially important given that Florida's fertilizer laws do apply to homeowners.

When rain falls on developed areas, it can become what is known as "runoff" or "stormwater". This is water that runs off roofs and driveways and into the street. As it flows, it picks up pollutants such as fertilizer, oil, pesticides, dirt, and bacteria. This polluted water then makes its way into storm drains and ditches and eventually flows, untreated, into streams, rivers, lakes, and the ocean.

Polluted runoff is one of the greatest threats to clean water in the United States. It can cause water pollution, increase flooding, and contaminate drinking water sources. It can also harm aquatic ecosystems and contribute to the formation of “dead zones” in the ocean—areas with minimal oxygen where coral reefs and other marine life cannot survive.

To protect watersheds and the environment, homeowners can take steps to reduce runoff and prevent water pollution. This includes properly disposing of motor oil, pesticides, and other chemicals, as well as minimizing the use of fertilizers and opting for more natural lawn care practices. Homeowners can also soak up rainwater by planting trees and other plants, which have the added benefit of beautifying neighborhoods and cooling the air.

By being mindful of the impact of runoff on watersheds, homeowners can play a crucial role in protecting the environment and preserving clean water sources for future generations.

Soil testing is important to prove a phosphorous deficiency and ensure compliance with local ordinances

Phosphorus (P) is a limiting nutrient for crop production in highly weathered soils. A low concentration of phosphorus in the soil can hinder crop growth and development and negatively impact agronomic yield. Therefore, it is important to conduct soil testing to determine the availability of phosphorus in the soil and make informed decisions about phosphorus fertilizer applications.

Different soil test methods are used to determine the total phosphorus available to crops, as well as the phosphorus that is susceptible to environmental loss. The choice of soil test depends on the purpose of the test and the specific characteristics of the soil type. For example, the Mehlich-1 test is recommended for non-calcareous soils with a pH of less than 6.5, while the Lancaster test is better suited for calcareous soils with a pH above 7.

In Florida, the presence of phosphorus in groundwater, surface water, and drinking water has been a concern. To address this issue, the state has implemented regulations and best management practices for fertilization-management practices. These practices aim to protect water resources while preserving a viable agricultural industry.

To ensure compliance with local ordinances and make informed decisions about phosphorus fertilizer applications, it is crucial to conduct soil testing to determine the availability of phosphorus in the soil. Soil testing provides an index of phosphorus availability to crops and helps farmers make data-driven decisions about phosphorus applications. By understanding the phosphorus levels in the soil, farmers can optimize their phosphorus fertilizer usage, reduce environmental losses, and improve crop yield.

In conclusion, soil testing is a valuable tool for proving a phosphorous deficiency and ensuring compliance with local ordinances. It helps farmers make informed decisions about phosphorus fertilizer applications, optimize their phosphorus usage, and balance environmental considerations with crop production goals.

Homeowners can take small actions, such as removing grass clippings and leaves, to reduce the amount of fertiliser that ends up in the water supply

In Florida, the improper use of fertilisers can negatively impact the environment and water supply. Homeowners can take small actions to reduce the amount of fertiliser that ends up in the water supply. One way is to remove grass clippings, especially from the curb, gutter, and near storm drains. If left in these areas, grass clippings can end up in drains and leach chemicals into the water supply. However, grass clippings can be recycled and returned to the lawn, providing valuable nutrients and reducing the need for nitrogen-based fertilisers.

Grass clippings can also be composted or used as mulch. When used as mulch, grass clippings should be dry and no more than 1-2 inches thick. They can be applied around flowers, vegetables, shrubs, and trees to reduce weeds, retain moisture, and moderate soil temperature.

In addition to removing grass clippings, homeowners can also pick up and dispose of fallen leaves. Leaves can be composted or used as mulch, which helps to suppress weeds, conserve moisture, and regulate soil temperature. By composting or mulching leaves, homeowners can reduce the amount of fertiliser needed and improve their soil's health.

Another way to reduce fertiliser use is to adopt sustainable practices such as utilising biochar, a form of charcoal produced from agricultural waste. Biochar enhances soil fertility, improves soil structure, and provides a habitat for beneficial soil microorganisms. It also helps retain and store nutrients, reducing nutrient runoff and enhancing their availability to plants.

By implementing these small actions, such as removing grass clippings and leaves, and adopting sustainable practices like biochar, homeowners in Florida can play a crucial role in reducing the amount of fertiliser that ends up in the water supply, thereby protecting the environment and their own health.
