Food web analysis of coffee crops fertilized with cow manure (CM), poultry litter (PL), plant residues (NF), and in a forest fragment (FF). Quadrant A: enriched and structured agroecosystem; quadrant B: mature and structured environment; quadrant C: mature and stable environment, fertile soil; and quadrant D: degraded and depleted soil. (Ferris, 2010).
