The âPerc Testâ. A Perc Test (also known as âPerk Testâ, and more formally known as a Percolation Test), is a soil evaluation that tests the rate at which water drains through soil.
Labs, such as those at Iowa State and Colorado State University, recommend that a soil test contains 10-20 sample points for every 40 acres (160,000 m 2) of field. Tap water or chemicals can change the composition of the soil, and may need to be tested separately. As soil nutrients vary with depth and soil components change with time, the depth and timing of a sample may also affect results. Composite sampling can be performed by combining soil from several locations prior to analysis.
