Drip line irrigation is a great idea for gardeners who want to save water and grow plants successfully.
By soaking the ground with water, the drip line approach mimics the effect of a gentle soaking rain, instead of battering leaves with a harsh jet of water like so many sprinkler systems do. More importantly, by slowly delivering the water to the soil and plants and not spraying it overhead the air, a drip line system can better target, and thereby reduce, the water needed for landscape or edible plants.
For a long time, ecologists have believed—and others accepted—that when it comes to whether a land mass is covered with forests or grasslands, climate controls the show. They thought that the amount of rain, temperature and frequency of wildfires determine whether the ground will be covered with trees or grasses. Maybe not, say two scientists.
