| Abstract | ||||
| The present study aims to characterize the soil properties thought to be of close importance to the fertility status of the soil. This attempt was conducted in a sort of “a case study” on soils of the Experimental Farm of the Faculty of Agriculture of Sohag which covers an area of about 200 faddans being ¡n two almost equal locations. Forty soil profiles, were selected with an average of 5 faddans for each profile. The soil samples (133 samples) were collected according to the morphological variations among the entire depth of the profiles and analyzed for the physical, chemical and fertility determinations. Results was be summarized In the following :- - Soils of both locations are mostly coarse ¡n texture, which becomes finer with depth in some profiles. Most of soil samples moderately or strongly alkaline. Soil salinity showed to be variable being non-saline to very strongly saline. - Soils of both locations are highly calcareous, being widely variable. - Most of the soil samples contained Q. M. of less than 1% and decreased with depth. - Soil are characterized as being low and very low ¡n nitrogen, indicating the need to apply more N through fertilization. - The tested Soils exhibit moderate to very high values of ‘available P, ¡ndìcatêng no need to apply more P. - Soils of experimental sites contained low to high levels of extractable K. 35.71% and 61.90% of the collected samples are Fe-deficient, whe 64.29% and 38.10% of those samples are Fe-marginal. - 35.86% and 15,87% of all soil samples taken, represent Mn-deficiency depending on farming duration in both locations. - All soil samples are Zn non — deficient. - AIl studied soils contain more than 0.2 ppm DTPA-extractable Cu, indicating no Cu deficiency. | ||||
