Chapter 4.1

Three reasons for getting an accurate •

estimate of manure volume or weight: to estimate the required land base for manure utilization, to determine if the operation is subject to additional requirements under AOPA and to develop a time estimate for manure application. Estimating the weight of solid manure •

involves determining pile shape, measuring or estimating key dimensions, calculating pile volume and determining density. Estimating the volume of liquid manure •

involves determining shape of the storage facility and obtaining key dimensions.

To calculate the volume of a cylindrical •

storage facility the height of the manure in storage and the diameter of the storage facility are required. To calculate the volume of a tapered prism •

storage facility the following dimensions are needed: top length and width, slope of storage facility walls, length of sloped wall of the facility and length of freeboard. Ideally, manure volume and weight •

should be determined as close to the time of application as possible. Liquid manure volume should be estimated prior to agitation of manure in the facility.
