  • The Ecology of the Fish Pond Ecosystem

    An understanding of the ecology of a fish pond is essential for the achievement of steady and high fish production in ponds. For the ecologist, the fish pond is a small laboratory: easy to investigate and responding rapidly to manipulation. For the aquaculturist, the ecology shows the ways and means of interventions ensuring an increase of ...

  • Sulphur in Agroecosystems

    This is the second volume in the series Nutrients in Ecosystems. Sulphur as an essential plant nutrient has received little attention. This is explained by the facts that sulphur was obviously in sufficient supply from the atmosphere, from soil and as a by-product in mineral fertilizers. Increases in the yield potential and thus in the ...
