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.
The amount of organic material can be determined by ignition. Organic material is made of carbon compounds, which when heated to high temperatures are converted to carbon dioxide and water. In the ignition process, a dry solid sample is heated to a high temperature. The organic matter in the soil is given off as gases.This results in a change in weight which allows for calculation of the organic content of the sample. Oven-dry the sample to remove water (see soil moisture). Weigh a crucible and lid, evaporating dish and cover, or other covered container.he organic matter in the soil is given off as gases. This results in a change in weight which allows for calculation of the organic content of the sample. Oven-dry the sample to remove water (see soil moisture).
