1. Stop Using Chemical Fertilizers.
Chemical fertilizers often contain salt and other compounds that are harmful and/or deadly to worms. If you have enough worms and other organic fertilizers in your soil, there is no need for synthetic fertilizers. Earthworm castings (worm excrement) can contain as much as 10 times the amount of plant-available nutrients as the original soil. This nutrient-rich natural fertilizer is teeming with microorganisms that live in the worm’s gut.
Worm castings have high concentrations of two important components for soil health and plant growth: humic acid and mycorrhizae. Humic acid helps plants develop stronger root systems, increases microbial activity and nutrient availability, promotes the activity of enzymes and natural plant growth regulators, as well as, slowing pathogenic fungi build-up. Mycorrhizae, a beneficial soil fungus, attaches to the root system in a symbiotic relationship that helps the roots to absorb nutrients and increase water intake. Basically, a worm’s gut is filled with good microbes and bacteria that are distributed in the garden as they travel and munch throughout the day.
