By tunneling and casting, worms improve soil aeration and nutrient distribution. 5. The project failed to improve plant growth. Answer: FALSE
Traditional soil remediation is often too expensive . worms put new life into derelict site reading answers
Earthworms consume organic matter alongside mineral soil particles. As this material passes through their digestive tracts, it is chemically altered and excreted as "castings." Earthworm castings are an environmental goldmine; they are rich in highly concentrated, easily absorbable forms of nitrogen, phosphorus, potassium, and calcium. By redistributing these nutrients throughout the soil profile, worms effectively recreate the fertile topsoil layer that derelict sites lack. 3.
