The video tutorial explains percolation, the movement of water through soil, and how it varies with soil types. It covers percolation tests, which measure the rate of water movement, and provides a step-by-step guide to conducting these tests. The tutorial also discusses how to modify soil percolation rates to improve plant growth by adding materials like loam, compost, or sand.
