Assessing texture Crush the soil sample by hand, or with a mortar and pestle if necessary. Remove any roots and gravel. The sample should be the size of a golf ball. 1 Hold the sample, moisten it, and work it by hand until it is consistently moist throughout. It should not be sloppy or drip water. Note: heavy clays will take time. 2 Next feel the bolus of soil between the fingers and evaluate its feel against the second column of the table. 4 5 Now shape the sample into a thick cigar shape. Finally flatten the cigar gently to about 10mm thick by pressing it out between thumb and forefinger. Push it away from you as a ribbon of soil. 6 Shape the sample into a bolus (ball). Assess it for coherence against the first column of the Soil texture table. 3 When the ribbon breaks, measure the length of the section it forms. Do this a few times to get an average ribbon length. Evaluate the average length against the third column of the table. 7 Determine the soil texture by looking at the fourth column on the table opposite. Write the soil’s texture on the Soil Health Bullseye Score Card. RASH MANUAL - 11
