Tips To Get Rid Of The Smell Of Manure In The Soil

Mixing

Mixing manure well into the soil is an essential step when using manure as a fertilizing agent and as a soil amendment because it evenly distributes important nutrients and improves the structure and moisture retention qualities of your soil.

You should be doing it regardless. However, doing so will also significantly reduce the offensive aroma it tends to leave behind.

  1. Begin by preparing the area where you will be mixing the soil and the manure. Make sure that you remove any vegetation and debris, and level the ground as much as possible.
  2. Using a rake or manure spreader, evenly distribute your manure of choice over the soil.
  3. Next, use a tiller or garden fork to turn the soil and mix it in the manure.
  4. Finally, use your rake to level the soil and leave behind an even, smooth surface.

Mix your manure and soil properly or you will end up with a potentially overwhelming and unpleasant smell.

Carbon-Rich Materials

A nifty little trick to get rid of the smell of manure in your soil is to add some carbon-rich materials into your mix.

Carbon-rich materials will help you get rid of the pungent manure smell by speeding up the decomposition of the manure.

You see, the smell of manure is produced mostly by the release of ammonia, methane, and hydrogen sulfide molecules during a decomposition process. If you speed up this process, these gaseous molecules will hang around less and the smell will dissipate much faster.

There are several carbon-rich materials that can be added to manure without affecting its ability to enrich your soil.

  • Leaves: an excellent source of carbon, leaves can be added whole or shredded.
  • Sawdust: this byproduct of woodworking is another excellent source of carbon for your manure, and sawmills or woodworking shops often just give it away for free.
  • Cardboard: shredded cardboard is another excellent source of carbon for your manure. It is biodegradable and very cheap.
  • Coffee Grounds: coffee grounds, the type you have left over after brewing some coffee, are rich in carbon and also contain beneficial microorganisms that further boost decomposition in your manure.

Water The Soil Thoroughly

Another very simple trick to help you reduce the smell of manure from your soil is to ensure the soil is properly and thoroughly watered.

Watering the soil thoroughly will help to get rid of the smell of manure by diluting the concentrations of odor-causing ammonia, methane, and hydrogen sulfide in the manure. Any other odor-causing compound will also be diluted.

Soil Conditioner

Using a soil conditioner to get rid of the smell of manure in the soil is a very simple process.

The very first thing you need to do is to spread your chosen soil conditioner over the area where the soil most stinks of manure. The amount of soil conditioner you will need will depend on the size of the area you wish to treat as well as the intensity of the smell.

Next, use a rake or similar tool to mix the conditioner into the soil, this will allow the condition to do its intended job as well as reach deep into the soil, making it a more effective deodorizer.

After the conditioner has been properly mixed into the soil you must water the surface, as this will work to further “activate” the conditioner product.

Don’t be disappointed if you need to apply soil conditioner to your manure more than once. As always, when using a commercial product it is important that you follow the manufacturer’s instructions well to get the most out of the product.

Soil Deodorizer

If soil conditioner is not readily available, consider getting yourself some yard odor remover such as this wonderful Natural Yard Odor Remover Deodorizer from Smelleze (on Amazon).
