Would you like to know how to dispose of your fertilizer that hasn’t been used? It depends on the level of danger posed by the fertilizer. You probably apply fertilizers frequently if you like showing off your lush, green lawn or gorgeous garden.
Types of fertilizers
On the market nowadays, there is a variety of fertilizers to choose from:
- nitrogen, phosphorus, and potassium-containing chemical fertilizers;
- organic fertilizers including plant materials, animal waste, or minerals that increase nutrient availability in the soil;
- biosolids, which are sewage sludge that has been treated;
Organic fertilizers that are certified can be safely used on lawns/gardens and pose minimal harm to the environment. Chemical and bio-solid fertilizers are classified as hazardous waste and should never be thrown away or flushed since they may pollute local water supplies.
Phosphorus, a key component of synthetic fertilizers, promotes algae development, which depletes oxygen in lakes, rivers, and streams, destroying fish and other aquatic life.
Organic fertilizers are usually safe for the environment. Chemical and bio-solid fertilizers, on the other hand, are considered hazardous waste. Users should never dispose of them in the garbage or flush them down the drain. This kind of improper fertilizer disposal will pollute local water supplies. The reason for this is that these fertilizers include phosphorus, which promotes algal development.
The oxygen in rivers, lakes, and streams will be sucked away by algae. This harmful side effect has a negative impact on the fish and other aquatic animals that live in these bodies of water. When this happens, it may rapidly wreak havoc on your neighborhood’s ecology.
How to dispose of organic fertilizers?
Excess organic fertilizer may be easily disposed of by adding tiny amounts to your compost pile or distributing it thinly around your yard and garden. The natural components should break down rapidly, providing a boost of nutrients to all of your plants.
How to dispose of chemical fertilizers?
Chemical fertilizers don’t get quite the same amount of flak as pesticides, herbicides, and fungicides when it comes to environmental harm, but they should. Widespread chemical fertilizer usage in an urban setting has large-scale cumulative negative environmental consequences, such as leaching pollution of groundwater supplies and the development of algal blooms in surface water that exhaust the oxygen reserves needed by marine life.
Proper disposal, on the other hand, helps to minimize the chemical imprint you leave when you apply them. Fortunately, most towns offer designated hazardous household waste (a.k.a. HHW) pickup days, permanent HHW disposal sites, and planned collection events where you may drop them off.
This is how you should get rid of a chemical fertilizer:
- Place your leftover fertilizer in its original container outdoors for collection by your sanitation agency on hazardous waste pickup day;
- Bring your leftover fertilizer in its original packaging to an HHW facility or a local collection event. Some HHW facilities enable you to swap your old fertilizers and gardening chemicals for items left off by others;
- Give your unused fertilizer to another gardener in its original packaging with the label;
- Take your leftover fertilizer in its original packaging with the label to a garden center. Gardening shops have to dispose of leftover chemicals. They are obliged by required by municipal, state, and federal laws to take your fertilizer for recycling and disposal;
- Before putting away empty fertilizer containers, rinse them 3 times with water;
- Dispose of it in a pile in your garden, or compost – it may inflict chemical burns on plants and kill important microorganisms;
- Flush liquid fertilizer down the drain or sink;
- Throw liquid or granular fertilizer straight into the garbage;
- Let children and pets play around with a fertilizer;
- Dump a large amount of “natural” fertilizer in one place is safe for plants;
- Mix various kinds of fertilizers since a hazardous chemical reaction may develop;
How to throw away old or expired fertilizer?
Although the chemicals in liquid fertilizers are beneficial to grass, they are classified as hazardous waste. Obviously, the garbage is not the ideal location to dispose of used fertilizer. Phosphorus, nitrogen and potassium are the primary components. If these chemicals get up in lakes or streams, they may be lethal to fish.
If you have no other choices, triple bag an old fertilizer in dense garbage bags. Seal each bag completely. Inform your garbage collection company that you have fertilizer in your garbage. This should be done only as a last option and in tiny quantities. Never throw fertilizer down a storm drain or a sink.
Here is what you require:
- A large zipped/plastic trash bag;
- Original fertilizer bags or containers;
Throw away old or expired fertilizers in such a way:
1) Gather old fertilizer
Gather all of the chemical or bio-solid fertilizer that you want to get rid of from your garden shed, basement, garage, or other storage places. Store fertilizer in the original container or bag to avoid mixing it with other items you are discarding. To begin using liquid fertilizer, make sure the lid is securely fastened. To prevent the top from unscrewing, wrap it with tape around the opening. When storing granular fertilizers in a plastic bag, wrap the bag down firmly and tape it shut. Pour the fertilizer into a Ziploc bag if it is loose in a box. Avoid handling the fertilizer, breathing fumes or particles from it, or allowing it to go into your eyes.
2) The newspaper is laid out
Lay down sheets of newspaper that are at least three thicknesses thick. Wrap each fertilizer bag or container separately within the layers, applying tape to hold them closed. Wrapping the fertilizer in the paper provides an extra layer of protection from spills. Use many sheets of paper to soak up any fluid that may leak from the container as it goes from your trash bin to the truck.
3) Each item has to be double sealed
Open a big enough plastic or Ziploc bag to fully seal around every newspaper-wrapped package or container of fertilizer. Place the fertilizer into the bag and secure it with a knot or zip the bag seal tight. To prevent fertilizer from leaking out, secure the bag’s seal with tape. If the plastic bag is flimsy, you may wish to add one more layer of newspaper around the entire unit before placing it all in another plastic bag to finish the process.
At this time, you may securely dispose of the fertilizer in a trash bin for normal collection. If there are any leaks, the bag and newspaper should capture the material so it does not escape and wash into rivers.
Are fertilizers really hazardous?
Fertilizers are rich in potassium, nitrogen, and phosphorus. Herbicides and insecticides are also included in certain fertilizers. If these chemicals get up in lakes and streams, they may be hazardous to fish and animals. Never throw fertilizer down a storm drain or a sink. Examine the bag. The package of many fertilizers will provide disposal instructions. If you have unexplained packages of fertilizer, it’s generally prudent to presume they contain dangerous chemicals. It is preferable to use safe disposal methods.
How long does a lawn fertilizer need to dissolve?
Most synthetic fertilizers include a quick-release formula, which implies they dissolve nearly instantly and provide effects in a few days. Organic, slow-release fertilizers include extra nutrients for your grass, such as bone/fish meal, and fish emulsion. This may seem disgusting, but it is beneficial to your grass. It also requires longer breaking down, and effects may take 2-6 weeks.
How to find local fertilizer disposal?
Once or twice a year, many communities host trash/waste events. To locate one in your region, contact your local trash management agency. For additional information on appropriate disposal, call the National Environmental Hotline.
