You can just put the manure on the top of the soil and leave it, which will work. I prefer to dig it in to the soil because I find it breaks down quicker and the benefit of the manure is spread throughout the soil. It also stops lumps forming.
You can spread compost and dig it into the soil for raised garden beds, but the effort is optional. It's good enough to simply sprinkle it along the surface and let the seasonal rains carry the nutrients all the way to the roots.
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.
How & Where To Use It In The Garden. Horse manure compost can be used just as you would use any other composted material in your growing areas. Traditionally, gardeners dig well-rotted manure into their soil.
Spread your compost over the whole area, including around any plants that are left. You don't even have to dig it in if you don't want to, as it will gently rot in over winter. In spring, again spread it over the whole area.
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. Pig, dog, cat, and human waste should never be used in a vegetable garden.
Dig and Drop Composting
Dig a hole, approximately 10 to 12 inches deep and as wide as you want or need it to be. Drop food scraps or other organic matter into the hole. Replace the soil, and you're done.
Ideally, you should dig in your green manure three to four weeks before planting new crops, and at least a month before sowing seed.
For best management practices, manure should be applied to a garden no later than 90 days prior to harvest of non-ground-contact crops such as trellised tomatoes, cucumbers and peppers; and no later than 120 days prior to harvest of ground-contact crops such as lettuce, strawberries and carrots.
Decomposition will be complete anywhere from two weeks to two years depending on the materials used, the size of the pile, and how often it is turned. Compost is ready when it has cooled, turned a rich brown color, and has decomposed into small soil-like particles.
Adding fresh horse manure to your garden will add a lot of nutrients but also carry bacteria and weed seeds with it, which can cause damage to your garden in the long run. What is this? The best way to use horse manure is to compost it first before using it on your garden.
Horse manure is rich in nitrogen, which promotes the development of leaves and plant growth but can inhibit the development of fruit on the plant. Consequently, vegetables such as tomatoes, chilies, sweet peppers, peas, beans, cucumber, and other fruiting plants will not produce high yields when fed with horse manure.
One rule of thumb: the more green material (cut grass, weeds, leaves) you put in, the less water you'll need to add. In fact, if you need to add dry ingredients such as straw or hay, soak the material first in water so it won't dry out your compost pile. In general your compost should be moist, but not sopping wet.
The final step in the process is to water your newly composted lawn. This helps the compost to seep further down into the soil.
Almost everyone advises putting down a layer of coarse material — corn cobs and husks, sticks, thick fibrous stalks from vegetables, or tall flowers. This layer improves aeration at the bottom of the compost pile.
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 around 150g per square metre (150g/m²), or 5 oz per square yard (5 oz/yd²) in imperial measurements, prior to planting, and then apply 100g per square metre (100g/m²), or 3.5oz per square yard (3.5 oz/yd²), every 8-10 weeks during the growth period if desired.
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.
Always use composted manure
Fresh or raw manures are more concentrated in nutrients and will burn your plants. Sheep and especially poultry manure are considered “hot” and may burn seedlings and transplants, inhibit seed germination, or make your perennials grow so fast and thin that they fall over.
The major difference between compost and green manure lies in their composition. While green manure is made from animal-based waste products such as urine and feces. Adding compost to the soil enriches the soil with organic matter while green manure increases the nitrogen level of the soil. Was this answer helpful?
In-Place Composting
Bury the material at least 12" deep and then cover with at least 8" of soil to discourage dogs, cats or other animals from digging it up. Rotate the site of composting to avoid over-concentration of material in one spot.
Composting becomes even easier without compost bins. Burying the compost directly in the garden bed reduces time and energy spent. Vegetable plants still get the same benefits of traditional composting methods.
General Composting Rules
Locate the composting pile on level, well-drained ground near a water source. Stay away from wooden fences and buildings. Don't set up over shallow tree roots. Mix Greens (for nitrogen) with Browns (for carbon) at a 2:1 Green/Brown ratio.
