Green up your Landscaping by Limiting Fertilizers: A Look into the Negative Ecological Impacts of Fertilizers

knoxville green team

Lawn and garden fertilizers are often used to make plants grow quicker and lusher.  However, the over use and incorrect uses of fertilizers can pose serious negative environmental impacts.  First let's focus on how fertilizers work- three of the major chemical component of fertilizers are Nitrogen (N), Phosphorous (P), and Potassium (K).  These essential nutrients are required for plants to grow, absorb energy from the sun, and undergo metabolic activities.  All three of these chemicals N, P, and K are present in the soil via the decomposition cycle of dead plants and animals.  However, many homeowners often unknowing deprive their lawns and plans from these essential nutrients by packing up all the "yard waste" and sending it off to the dump.  This is one important reason in which composting is important to overall soil health- read more about Composting in my Composting 101 Post.

Fertilizers can be effective in producing larger, more vibrant plants, and in the case of fruits and produce- better crops.  This may sound great for the plant, but the major negative impact occurs when this nitrogen ends up somewhere other than just your plants and garden.

In order to prevent excess fertilization from entering into our water sources homeowners need to be aware of these issues and how to prevent them.  First, make sure that if you must use fertilize, use only what is neededGreen living in knoxville tn and don't fertilize in excess.  If you live in an area with softer soil use slow release fertilizer.  However, if you live in an area that contains hard soils or clay (as is often prevalent in East TN) you should opt to use fast release fertilizer (if absolutely necessary) to avoid having the fertilizer hit the water sources.   In addition, before you fertilize take a few seconds to check the weather forecast and make sure there is no rain in the near future as a rainfall will increase the chances of it getting into the water.  Also, be sure never to apply fertilizer near a water source or wash, dump, or rinse fertilizer down the drains, into the street, or into a sewer drain.

Water is essential to our survival and is also a non-renewable water source so we need to be cautious and proactive about protecting this invaluable natural resource.
