| Abstract | ||
| Six soil profiles representing the clayey soil of El - Gemmeiza Experimental Station , EI-Gharbia Governate were chosen to study the effect of different irrigation systems (surface, sprinkler, drip) on soil fertility status. Results show that the values of available phosphorus, potassium and organic matter contents were negatively significant correlated with different irrigation systems. Available nitrogen values were significantly negatively correlated with sprinkler and surface irrigation systems, how-ever they showed insignificant negative correlation with trickle irrigation system. On the other hand, it can be stated that no distinct trend could be observed between N, P, K and organic matter contents with the different irrigation systems. The surface layer of the soil contained the highest available nitrogen , phosphorus, potassium and organic matter contents with a tendency to decrease as soil depth increases. | ||
