The requirements for weight determination of solid animal manure are supplemented to increase the reliability of the weight determination and further restrict the risk of manipulation. Determining the amount of discharged and supplied manure is essential for the accountability of the flows of manure and nutrients. In practice, various incidents with regard to weight determination have been observed so that a higher weight of discharged solid manure was registered than was actually discharged.

A number of additional requirements are laid down for the determination of the weight of solid animal manure (Article I(F)). A cargo of manure must be weighed immediately after the start of the transport and the weight of the empty vehicle must henceforth always be determined before the transport. During transport, the carrier must have proof of weighing of both the cargo and the empty vehicle, and this proof must include a number of specified data. The carrier must store the proofs of weighing in its administration for a period of five years.
