خلاصة
Al-Hinya is known as a coastal area and is one of the largest areas of the coastal municipality. It is considered one of the most important agricultural areas in Jabal Al-Akhdar, about 25 km away from the city of Al-Bayda.
Al-Henya area is of economic importance because of the crops it produces capable of meeting all the needs of Jabal Al-Akhdar. This makes the soil of the area in a state of depletion of its nutrients or even subject to deterioration as a result of intense pressure on it with fertilizers. Therefore, this area was targeted to monitor the condition of the soil in it and follow it during two different seasons.
Forty sites were randomly selected to take soil samples that differ in terms of their proximity and distance from the coast. The samples are located at different altitudes from sea level. A number of wells used by farmers for irrigation were also selected. The study included routine procedures for soil by studying the chemical properties of the soil as well as the chemical properties For irrigation water, and therefore to determine its suitability for irrigation compared to global measurements issued by the US Department of Agriculture), USDA, 1954) and about the Food and Agriculture Organization (FAO, 1985)
Chemical analyzes consist in knowing the degree of electrical conductivity "EC", the degree of pH and dissolved ions in addition to the use of many mathematical indicators that included the percentage of sorbed sodium "SAR" and the modified "RSC" and residual sodium carbonate "RSC" in addition to some other mathematical indicators for irrigation water.
