Method 1—Best for Solid Manure
Equipment required: a plastic sheet (6 ft × 6 ft or 10 ft × 10 ft), a scale (milk or bathroom scale), and a bucket.
6 ft × 6 ft
10 ft × 10 ft
- Weigh the sheet with the bucket on the scale.
- Lay the sheet in the field where manure will be spread. Place the sheet at a distance from yourself great enough to put the spreader in gear and bring the load.
- Drive the tractor and spreader over the sheet.
- Fold the sheet so that no manure is spilled. Put the sheet in the bucket and weigh both on the scale.
- Subtract the weight of the empty bucket and sheet in Step 1 from the weight of the sheet and bucket filled with manure. This number is the weight of the manure collected on the sheet.
- Repeat the procedure and determine an average for the weights.
- Taking into account the size of your sheet, use the average weight and Table 1.2-16 to determine the tons of manure applied per acre.
- If you are using a different-sized sheet, or if the amount of manure collected is not listed in the table, use the following formula to calculate tons per acre:
(lb manure × 21.8) ÷ sheet size (sq ft) = T manure/A
