These beds are looking alive! Blumat systems keep constant, steady levels of moisture in soil. The regular supply of moisture keeps microbial communities happy, in homeostasis, and with the ability to multiply. With hand-watering systems, the dry/wet cycles can stress out bacteria and other microorganisms. When these organisms are stressed, they produce chemical compounds that can negatively affect your soil (anyone who has seen hydrophobic soil, or water that runs off the top of a container has seen this 1st-hand!) and plant health. Hydrophobic soil is actually due to water-resistant glues produced by bacteria. The bacteria sense an impending drought, and produce a membrane around their colony that prevents moisture from escaping. However, this membrane also prevents moisture from getting in if the bacteria die. When you water your soil after it dries out, you might notice water running off the top and over the sides of the pot, rather than integrating with the soil. You’re watching the water contact these membrane compounds produced by bacteria. These compounds are not easy to remove! By keeping your microorganisms healthy and happy, your soil and plants will stay happy too.
