Soil nutrients play an important supporting role in ecosystems, which cannot function without these vital components. Practices such as planting more vegetation, building retaining walls, and preventing water runoff contribute toward maintaining healthy soil nutrient levels. Why are practices like these important, and how do they benefit the ecosystem? How can you apply this to your life and make the world a better place?
