Answer to Question 1

1 . Polycultures have greater tolerance to environment and pest stress and provide insurance against total crop failure. Should one of the crops die, other species can still produce yield. This is sometimes called yield stability.
2 . Polycultures of woody crops and pastures in silviculture systems provide for diversification of income by providing short-term and long-term income and products for different markets.
3 . Polycultures with plants of different nutrient needs and rooting characteristics have the potential for greater use of light, water, and nutrient resources and greater overall productivity per acre. Polycultures of nitrogen-fixing legumes with annual or perennial grasses are less dependent on nitrogen fertilizer inputs.
