Invloeden van oppervlakte-infiltratie ten behoeve van duinwaterwinning op kruidachtige oevervegetaties

摘要: The vegetation has been analysed by using various ecological parameters. Among the three main macro-nutrients (phosphate, nitrate and potassium), the supply of phosphate due to flowing ground water shows a very significant and probably causal relation with the applied vegetation parameters. In non-infiltrated areas, the supply of macro-nutrients due to mineralization of organic matter appears to dominate the supply due to flowing ground water.
