Based on this data, a special penetrometer probes selected areas of the soil for additional information, such as soil compaction, texture, color and electrical conductivity. Although wind erosion of overgrazed dune grass produced the first sand bunkers in 19th-century Scotland, the 21st-century approach at Pelican Hill was a lot more scientific: Three different sand compositions were tested and a device called a penetrometer was used to measure ``plugability'' before the sand chosen was deemed best for composition and playability. In a step toward that goal, Raper has developed a multiple-probe penetrometer for measuring soil strength, which collects data that can be used to create precision farming maps for tilling. |
