<br/><br/> A laboratory experiment was conducted to study the effect of some soil amendments i.e. biogas manure (BM),chicken manure (CM), taffla material (T), sulfur (S) and two water capture fertilizers (acidic and neutral WCF) on nitrogen behaviour through intermittent leaching using sandy and calcareous soils. The soil amendments were used individualy and in different combinations.
