Procedures: Survey Systematic Manual Soil Sampling Systematic Manual Soil Sampling Upon arrival at the premises to be surveyed by systematic manual soil sampling, the inspector should do as follows: 1. Look over the land. 2. Determine the boundaries and size and shape of the field. 3. Look at the field and determine the width and length. 4. Plan how the property should be surveyed. 5. Divide the property into a grid and record the grid on the field map or in the notebook. 6. Sample the field following the map grid pattern. A. Completing sample in a uniform method should provide the correct soil sample size for processing at the laboratory. B. If golden nematode infestation is found, then returning to a specific block within the grid should be easier.

Procedures: Survey Systematic Manual Soil Sampling 8-by-8 (8 x 8) Block Method In the manual survey 8 x 8 Block Method, fields are divided into units of approximately 2,080 square meters (half an acre), usually 16-by-224 paces (1 pace = 2-1/2 feet long). The 8-by-8 block sampling method has 56 sample points. The soil sample bags should each contain 56 scoops of soil and weigh between 4 and 6 pounds. 1. Divide the field into units. 2. Determine the number of bags needed in the first tier (length of an edge of the field in a straight line), as follows A. Pace the length of the field. B. Divide the number of paces by 224 to get the number of sample bags required for each tier. If the remainder is over 80 paces, then add an additional bag to the tier. C. Place the sample bags for the first tier, then take 16 paces and place the sample bags for the second tier, and continue pacing and placing bags for each consecutive tier. D. If the last tier is less than 16 paces wide, then each soil sample bag for this tier will cover an area approximating the square area covered by the standard bags in the other tiers. 3. For the initial survey, sample each area in the grid pattern by collecting one scoop (or dip) of soil every eight paces and placing the soil in the sample bag. 4. For more intensive surveys, take one scoop or dip of soil at 4 x 8, 4-x-4 or 2-x-2 pace intervals.
