This is especially important when the farmer is offering a new or different product that the customer has never tried before. Since farmers markets sell primarily on taste, sampling is a top marketing tool.

In this standard, sampling procedures for ROM and sized ores have been covered. With typical export consignments being around 15 000-20 000 MT, the sampling procedure covers all types of ores and accounts for optimum sizes of gross samples.GRAB SAMPLING This method can be used on a stope after blasting at a mine car or in the transportation of ore. This work faster than chip sampling. Samples taken at random. This method also does not provide a thorough overview that can represent the existing ore deposits. 3. BULK SAMPLING In bulk sampling, samples are taken in large quantities.
