Soil immunity and ecological concerns
Soil immune system is a network of soil, microorganism, plants that work together to protect from infection. It is a soil defense mechanism against harmful invaders and other inflections. Without it, the soil, the farmland will constantly get sick from viruses or diseases. Ecology concerns the interactions among organisms and their environment. It is an interdisciplinary; inter relationship between soil, Organism and plants work in an equilibrium for plant growth. Overuse of fertilizers, chemical, pesticides, row manures upset the soil ecology, stop the microorganism activities, interrupt the soil immune system and will kill the soil eventually.
