Figure 4.6.1 Volume Calculations for Various Manure Application Equipment.

Follow the steps below to use the load-area technique to calibrate application equipment.

Determine the Capacity of the Manure Spreader 1.

Manufacturer’s specifications will usually include the capacity of the spreader. However, for solid spreaders the capacity reported is often for a level or ‘struck’ load. If using heaped loads or if capacity of the spreader is unavailable, the capacity of the spreader will need to be estimated (Figure 4.6.1).

The manufacturer’s capacity specification may need to be converted into units that are compatible with those on the manure test report and used to express the recommended application rate (Table 4.3.3, Chapter 4.3). Record the capacity (specified or estimated) of the spreader.

Volume in cubic metres or feet can be converted into litres or gallons using the conversion factors in Table 4.6.2.
