What You'll Learn
Chicken manure pellets are easy to spread
Chicken manure is a great natural fertilizer for your garden or lawn. Chicken manure pellets are easy to spread and can be applied with any type of spreader. Pelletized chicken manure is available in bulk or in 50-pound bags.
Chicken manure pellets are a great option for those who want to improve their lawn or garden without using synthetic fertilizers. Pelletized chicken manure is easy to spread and can be applied using a variety of spreaders, including a broadcast spreader. Using a spreader to apply the chicken manure pellets ensures an even distribution, which is important for maximizing the efficient use of the manure's nutrients.
To optimize the uniformity of distribution, it is important to calibrate your spreader. Calibration is a simple process that can be done in less than an hour and can save you money by ensuring the efficient use of manure nutrient resources. There are two common calibration techniques: the swath or load-area method and the tarp or weight-area method. The swath or load-area method involves measuring the amount of manure in a typical spreader load and the land area covered by one load. This method is suitable for all types of manure but is particularly well-suited for liquid manure applicators.
The tarp or weight-area method, on the other hand, is recommended for solid manure applicators. This method involves weighing the manure spread over a small surface and calculating the amount of manure applied per acre. By using the tarp or weight-area method, you can determine the application rate by dividing the weight of manure collected on the tarp by the size of the collection area.
In addition to calibration, it is important to maintain a uniform ground speed throughout the swath length when using a PTO-driven spreader. Ground-driven spreaders, on the other hand, provide reasonably uniform application rates regardless of ground speed. By following these simple tips, you can ensure that your chicken manure pellets are spread evenly and effectively, providing your lawn or garden with the nutrients it needs to thrive.

Calibration of a manure spreader
To calibrate a manure spreader, it is important to first determine the application rate, which is the amount of manure applied per unit of land area. This can be calculated by weighing the spreader before and after spreading and determining the area covered. However, this method does not account for the evenness of the application. A better method is to collect samples at different points across the path of the spreader and weigh the amount of manure captured on a tarp at each point. The application rate at a given point can then be calculated using the formula: Application Rate (tons/acre) = Sample weight (lbs) x 21.8 / tarp area (ft2).
Another important factor in calibrating a manure spreader is determining the effective swath width, which is the width of the spreader path where the application rate is uniform. The distribution from a spreader typically resembles a triangle, with the maximum application rate near the spreader path and decreasing rates farther from it. The edge of the effective swath width occurs where the application rate is half the maximum rate. For example, if the rate is 4 tons/acre in the middle and decreases to 2 tons per acre 20 feet to the side, then the effective swath width is 40 feet.
It is also important to maintain a uniform ground speed throughout the swath length, as the application rate of PTO-driven spreaders depends on ground speed. Ground-driven spreaders, on the other hand, deliver relatively uniform application rates regardless of ground speed. For liquid application equipment, application rates and patterns may vary depending on ground speed, PTO speed, gearbox settings, gate openings, operating pressures, and spread widths.
In addition to calibration, good management practices include record-keeping. Maintaining records of calibrations and applications can help to improve the overall fertility of the farm operation and assist in troubleshooting problems. It is recommended to calibrate the spreader for each granular product used, as products vary in density, size, active ingredient, and nutrient content.

Using a fertilizer spreader for compost spreading
Another factor to consider is the type of compost being used. Fertilizer spreaders work best with pelletized or granulated compost, such as chicken manure pellets or worm castings. These can be easily spread using a fertilizer spreader and are available in bulk or in smaller bags. However, traditional compost with organic matter such as leaves, grass clippings, and food scraps may not be suitable for fertilizer spreaders due to the rotary disc design, which can result in uneven distribution and difficulty in applying thick layers.
Additionally, the size and capacity of the fertilizer spreader should be considered. Broadcast spreaders, for example, are smaller and may not have the necessary strength to spread compost over large areas, resulting in insufficient coverage. They also have limited capacity, which can make them time-consuming and labour-intensive to use for larger applications.
When using a fertilizer spreader for compost spreading, it is important to follow the operator's manual and make any necessary adjustments to ensure an acceptable spread pattern. This includes spacing the spreader paths at the correct intervals to achieve a uniform distribution.
Overall, while fertilizer spreaders can be used for compost spreading, it is important to consider the type of compost, the size and capacity of the spreader, and the proper calibration and adjustments to ensure effective and uniform distribution.

Determining the effective swath width
Understanding Swath Width
The swath width of a spreader refers to the width of the area covered by the fertiliser or manure during a single pass. This width can vary depending on the type of spreader used and the settings chosen. For example, drop spreaders distribute fertiliser in a swath equal to the width of the spreader itself, while rotary spreaders, also known as broadcast spreaders, distribute fertiliser in a much wider swath.
Choosing a Location
Select a paved surface or use a large drop cloth to catch the fertiliser during calibration. This is important to prevent over-application or spills that may be difficult to clean up.
Setting Up the Pans or Trays
Place shallow pans or trays in a straight line at specific intervals, such as 1-foot increments. Label the pans starting from 0 and leave a blank space between the 0 and -1 pans to account for the wheel of the spreader. The number of pans and their arrangement will depend on the specific instructions provided by the spreader manufacturer.
Filling the Hopper
Half-fill the hopper with the desired fertiliser or manure. This amount is usually recommended by the manufacturer to ensure accurate calibration.
Walking Speed and Direction
Push the spreader towards the pans at a comfortable, consistent walking speed. It's important to maintain a constant pace throughout the calibration process, as speed affects the distribution of the fertiliser. Approach the pans perpendicularly, starting far enough away to reach your desired walking speed before passing over them.
Making Passes and Weighing
Make multiple passes over the pans, ensuring that the spreader passes directly over the centre pan each time. The number of passes required may vary, but at least three passes are typically recommended. After each pass, record the location of each pan relative to its distance from the centre pan. Then, weigh the contents of each pan and record the weight.
Calculating Application Rate
The application rate at a given point can be calculated using the weight of the fertiliser in each pan and the formula provided by the manufacturer. For example, Application Rate (tons/acre) = Sample Weight (lbs) x 21.8 / tarp area (ft2). By calculating the application rate at different points, you can determine the effective swath width, which is the area where the fertiliser is distributed evenly.
Adjusting Settings
Based on the calculated application rate and swath width, you may need to adjust the settings on your spreader. This could include changing the spreader opening size, the walking speed, or the amount of fertiliser in the hopper to achieve the desired distribution pattern and rate.
Uniform Distribution
Achieving uniform distribution is essential for effective fertiliser application. Overlap the spreader paths to ensure even coverage. The specific overlap interval will depend on the spreader's effective swath width. By following these steps and making any necessary adjustments, you can determine the effective swath width for your walk-behind broadcast spreader, ensuring efficient and precise fertiliser application.

Manure spreader calibration techniques
Calibrating a manure spreader is a valuable tool to ensure the efficient and safe use of animal manures. It helps to maximise the use of available nutrients from the manure and avoid over-application, which can lead to environmental issues.
Firstly, it is important to note that each spreader is unique and should be calibrated separately, even if they are the same model. The same spreader should also be calibrated for each different operator, as differences in ground speed can affect the application rate.
The first step in calibration is to determine the effective swath width. This is the width of the spreader's path and can be measured by weighing the spreader before and after spreading, and determining the area covered. This will give you the application rate, or how much manure is applied per unit of land area.
The second step is to determine the spread pattern. The spreader should be adjusted until an acceptable pattern is achieved. This can be done by laying tarps in the field in the path of the spreader and collecting samples of manure on the tarps. The weight of manure collected on each tarp can then be used to calculate the application rate at that point.
The third step is to make any necessary adjustments to the spreader settings, such as ground speed, output settings, or application management, to achieve the desired application rate.
For liquid manure application, additional factors such as PTO speed, gear box settings, gate openings, operating pressures, and spread widths must be considered. Liquid manure can be applied to the soil surface or injected into the soil below the surface.
By following these steps and making adjustments as needed, you can ensure that your manure spreader is calibrated correctly and that the correct amount of nutrients is being delivered to your crops.
