One of the best ways to use manure as plant fertilizer is by mixing it in with compost. Composting manure eliminates the possibility of burning the plants. Another option is to till it into the soil prior to spring planting, such as during fall or winter. Generally, fall is the best time to use manure in the garden.
Blending manure into the top layer of topsoil will help encourage root growth and health because the manure is packed full of nutrients. The main nutrient released is nitrogen which is needed for plants and vegetables to grow in a sustainable manner.
Adding manure to the home vegetable garden can increase soil organic matter and may alter soil structure. Adding manure to soil will not change soil texture. Fall is the most common time of year for adding manure to a vegetable garden. The manure may be spread atop the soil or incorporated into the garden soil.
On other edible crops, fresh manure applications should be made at least three months prior to harvest. With just a four month or so growing season, this means you should only apply fresh manure in the fall; not in the spring or during the growing season to any area that is or will be planted with food crops.
Specialists at the University of Georgia recommend a rate of 150 pounds of cattle manure or up to 200 pounds of horse manure or 50 pounds of poultry manure per 1000 square feet of garden soil.
Manure that is piled and left alone will decompose slowly. This can take three to four months if conditions are ideal. It can take a year or more if the starting material contains a wide carbon:nitrogen ratio (as is the case when manure contains wood chips).
Apply nutrients in the spring just before growth starts. Avoid using manures and fertilisers in late summer or autumn where they may be lost over winter and pollute water bodies.
Pathogens, begin to die once incorporated into garden soil, and research has shown that incorporating manure at least 120 days before harvest greatly reduces risks of food borne illness.
Disadvantages of Manure
The manures are reported to provide fewer nutrients to plants, and they are unable to provide high-yielding crops. Manures are slowly absorbed by the plants, and they add a lot of humus to the soil. They are made in fields, so transportation is difficult for manures.
Cow manure is a great all-purpose fertilizer. It's low in nitrogen so it won't burn your tender plants, and has a good balance of nutrients. What's more, since a cow's four stomachs digest its food so thoroughly, very few weed seeds make it through, so you don't have to worry about them.
Simply ageing a manure pile for three months can kill about 60% of the weed seeds present, and bacterial counts start to drop within days after the manure leaves the animal. Then, when the aged manure is mixed into the soil, soil microorganisms clear out residual bacteria in about a month.
A: Your bagged manure will be fine for many years. It'll slowly break down and possibly become less "potent." I'd just let it sit out in the air for a day or two before applying it in spring with plants around; otherwise, apply it at the end of any growing season.
Cover your manure pile with a heavy tarp and good weights to hold it down against strong wind. You will keep the beneficial nutrients and you will not be polluting streams or groundwater.
Drag your fields at least once a year. Ideally, you would do this right after moving livestock from one pasture to the next as part of a rotational grazing system. Manure is easiest to collect from a dry- surface, all-season pen.
Spring is the preferred time to apply manure. Forage or hay crops generally provide the greatest flexibility in planning land application operations.

While adding additional organic materials to the pile can create a more nutritional fertilizer, it is not always necessary. Adding just enough water to keep the pile moist while turning it at least once a day can produce optimal results as well.
Fresh, non-composted manure will generally have a higher nitrogen (N) content than composted manure. However, the use of composted manure will contribute more to the organic matter content of the soil. Fresh manure is high in soluble forms of N, which can lead to salt build-up and leaching losses if over applied.
The pile should heat to 130-140 degrees. When conditions are ideal, compost can heat up within one day, Andrews said. After the pile cools down to an ambient temperature, transfer it to the second bin. It usually takes another two to six months to decompose or cure.
Ideally, the best manure for gardens is probably chicken, since it has a very high content of nitrogen, a need all plants have, but it must be composted well and aged to prevent burning plants. Chicken manure is a rich source of nutrients and is best applied in fall or spring after it has had a chance to compost.
Compost is ready or finished when it looks, feels and smells like rich, dark earth rather than rotting vegetables. In other words, it should be dark brown, crumbly and smell like earth.
You can also make standard store-bought potting mix go further by mixing it half and half with sifted composted manure. Composted manure is ready to use in potting mix when it has an even texture throughout and an inoffensive, earthy smell.
