Studies in temperate and sub -tropical Australia indicate that trees play a major role in nutrient cyclinge.g.Attiwell etal.(1978) and hence are important in maintaining system productivity andsustainability (Keith 1997).Trees access nutrients in deep soil layers and subsequently enrich thesurface soil through litter fall and deposition, increasing nutrient availability to shallower rooted lifeforms like grasses. Leaf litter also increases soil faunal activity, further improving soil condition viaincreased hydraulic conductivity, aeration and nutrient cycling. ...
