The drawing in the middle is from my book Drip Irrigation – For Every Landscapes & All Climates, it shows an ideal view of how the wet spots on the surface merge together 2-6 inches below the soil’s surface. The photo on the left shows the spots of irrigation on the surface of potting soil filling a horse trough. Notice how much of the soil appears to be dry. The other photograph shows the soil after I created a hole 4 inches deep – moisture is in the entire block of soil. These emitters are the 1/4-inch inline tubing with emitters every 12 inches. I’ll show, in later blogs, the resulting growth.
