This comprehensive treatise provides an in-depth understanding of allelopathy--the mysterious, complex biochemical interactions among plants and microbes. This little-understood phenomenon can lead to changes in nutrient dynamics, vegetation structure, and species diversity. Allelopathy in Agroecosystems explains how this interaction can be used as an environmentally safe method of weed and pest management. The fascinating original research presented here offers incalculable potential for rescuing farmed-out land, increasing crop yields, and cutting back on expensive soil additives.
