“…As for the lowest total nitrogen content that appeared in the fourteenth pedon, shown the same decrease in the content of organic matter was accompanied by the increase of one of them accompanied by a relative increase in the other, as the total nitrogen content increased with the increase in the content of organic matter, and this is also confirmed by many researchers that there is a direct relationship between the organic matter content and total nitrogen content in the soil (Prado et al, 2016;Mazzoncini et al, 2011; The previous table (3) shows the values of available nitrogen, phosphorous, and potassium in the soil, as the highest value of available nitrogen reached 77.00 mg. Kg -1 in the tenth pedon of the second transects, which is located at the end of the hydrosequences of the second transects, as the reason for this may be due to the fact that the available nitrogen is able to move with irrigation water or ground water and may be washed to lower areas with water courses in general as a result of irrigation or rainwater operations. The higher areas of the hydrosequences also showed a relatively low content of the available nitrogen and this is consistent with what Honeycutt et al, 1990found., Senthilkumar et al, 2009Ogeh and Ukodo, 2012. As for the available phosphorous in the soil presented in Table (3), it indicates that its highest value was located in the fifth pedon, which is located at the top of the hydrosequences of the first transects, also the thirteenth pedon in the second transects is a high value of available phosphorus, and the reason for this may be due to the increase in rural activity in the study area as well as to the severe agricultural conditions, since the soils of this pedon are planted with many crops such as wheat, barley, Medics.…”
