| Abstract | ||
| This study included knowing effects of land and well water exploitation in fertility characterization. The region of the study is characterized with dry climate and Level to nearly level slope. After field investigation about the nature of agricultural exploitation in the region as well as management method, four agricultural systems were chosen where their age not less than 10 years in order to get to the homogeny status in management manner. Five pidons were digged in study area. Soil samples were taken from each characterized horizon in order to study physical, chemical and fertility characterization while water samples, they were taken from wells water. The results showed the following: 1-The results showed that the EC for surface horizons which were used agriculturally between( 0.82 – 2.3 dS. m-1) while the surface. 2- The results showed tangible increase in soluble ion concentration of anions and cations in soil solution. The values of Calcium were between( 14 – 19.5 centimole charge kg-1) while magnesium values were between ( 6.9 – 11.4 centimole charge kg-1 ) while sodium values were( 6.3 – 19.2 centimole charge kg-1), potassium values were between (0.24 – 0.35 mg kg sol-1). Bicarbonate values were between (3.5 – 5.6 centimole charge kg-1) sulphate values (4.5 – 12.2 centimole chage kg-1) while chlorides values were between (17.7 – 29.3 centimole charge kg-1). 3-Available nitrogen in the study soils values were between (16.4 – 36.2 mg Kg soil-1), available phosphorus (13.95 – 43 mg Kg soil-1), available potassium (190.7 – 225 mg Kg soil-1), available iron (5.3 – 7.5 mg Kg soil-1) and available zinc (0.58 – 6.6 mg kg soil-1) and for all soils. 4-The results of the study showed that EC values for used in irrigation (well water) were between (2.2 – 4.30 dS. m-1) and pH (7.3 – 7.5). The values of SAR were between (1.6 – 4) and the classification of study water according to (USDA ,1954) was within (C3- S1) | ||
