The smell of manure can last from a few days to several weeks, depending heavily on application method, weather, and how well it's composted; fresh manure incorporated into the soil or dried on the surface usually fades in days, but poorly composted manure can smell for weeks, requiring more aging or mixing with browns (leaves, wood chips) to reduce odors, with fully composted manure having an earthy scent, not a foul smell.
If it smells I would let it cure in a pile and add biochar. There are many advantages of using biochar. You can also add more browns like dry leaves. When farmers spread raw manure onto fields the smell dissipates in a few days.
Methods to reduce bacterial growth include: killing bacteria with biocides and disinfectants, adding chemicals to raise or lower pH, cooling manure, pasteurizing manure, and keeping manure dry. Changing animal diets may also reduce odors. Nitrogen and sulfur compounds give off particularly strong smells.
While odor from manure storage and handling is emitted continuously, the amount of odor generated can vary. Increased odor release may occur during certain times of the year and during certain events, such as during agitation prior to land application.
Odors can travel several miles, depending on size and type of operation, topography and weather conditions. Reduce odors by not overloading lagoons and by frequently moving manure to storage instead of leaving it on open lots. Spread manure on dry, windy days for quickest odor dilution.
The hardest smells to get rid of are often deeply embedded, like skunk spray, cigarette smoke, pet urine, mold/mildew, and fire/water damage odors, because they permeate porous materials (carpets, upholstery, drywall, synthetic fabrics) and can get into HVAC systems, requiring professional cleaning or specialized ozone treatments to neutralize the odor molecules themselves, not just mask them.
Manure that is piled and left alone will decompose slowly. This can take three to four months if conditions are ideal.
In swine waste, all too prevalent malodorous compounds include ammonia, organic acids, alcohols, and—the most offensive of all—sulfides. Some of the compounds can have bad health effects on animals and humans. For example, chronic exposure to air with high ammonia concentrations can harm the respiratory system.
Depending on how much you mix and turn the pile, it may take anywhere from three to six months for all the manure to turn into compost.
Nonenal® (also known as 2-Nonenal) is a naturally occurring compound responsible for the distinct odor associated with aging. It typically appears after age 40, becoming more noticeable in both men and women.
Anti-Icky-Poo is the most highly effective odor remover available in the market place today and is guaranteed to permanently remove organic odors, including urine, feces, vomit, sweat, skunk musk, tobacco, char and even dead animal smells from virtually all surface materials without damaging the material.
Namely, on a per-animal-weight basis, poultry far and away produced the most ammonia emissions.

To Minimize the Health Risks Associated with Using Manures in Home Gardens. Wait at least 120 days after applying raw or aged manure to harvest crops that grow in or near the soil (root crops, leafy greens, strawberries). Wait at least 90 days for other crops.
Don't:
Proper use of manure in the garden can supply your plants with nutrients and help improve soil structure. Adding too much manure can lead to nitrate leaching, nutrient runoff, excessive vegetative growth and, for some manures, salt damage.
Desert areas do not have as much organic material as alpine/wooded environments, therefore decomposition takes longer. In some arid environments human waste will not break down for over a year. In desert environments it is recommended that you bury waste in a cat hole 4-6 inches in an elevated sunny environment.
Using pee: a how-to guide. Keep in mind that urine is very high in nitrogen. You may need to pee daily, but your plants don't need your daily pee. Choose plants that need lots of nitrogen, such as corn and squash, tomatoes and cucumbers during their fruit-bearing stage, and older plants that need a boost.
Most of the complaints we receive about odour relate to the storing and spreading of bio-solids (sewage sludge), slurries (muck spreading) and animal manures, particularly chicken manure (also called chicken litter), which has a strong odour.
The fertilizer smell typically lasts until below-freezing weather arrives, an air quality meteorologist for the state said.
Mold and Mildew: Some types of mold or bacteria outbreaks emit sulfur compounds that can smell distinctly like feces—especially if there's water damage under carpets, inside walls, or in the ceiling.
Once the spread manure has decomposed into the soil, the paddock can be safely grazed again, while the next paddock now at rest can take its turn at feeding from the spread manure.
Labor Intensive: Collecting, preparing, and applying manure requires significant manual labor. Odor Problems: Manure often produces a strong, unpleasant smell which can be a nuisance. Slow Nutrient Release: Nutrients in manure are released slowly, so it may not meet the immediate nutrient needs of plants.
