An ecosystem perspective on crop and soil management underscores the importance of
understanding the multiple interactions among the various flora and fauna that inhabit
soil systems and affect the success of any particular cropping system. By definition, pests
and pathogens have impacts on crops and other plants. However, conversely, soil and
crop management practices, together with the management of nutrients, water and other
plants, have demonstrable effects on the many populations of organisms that have
parasitic, toxic, or other impacts of significance to farmers.
