The Effect of Sulfur Powder Addition on the Chemical and Physical Properties of Soil in Jordan Valley

Abstract

The physical and chemical properties of soils in the Jordan basin examined by the addition of sulfur concentration and concern PH levels were determined. The sulfur was present in the soil in the form of organic matter. Plants cannot utilize it because the sulfur must release organic matter, then undergoes mineralization process resulting in microbial function. Increase of sulfur contents in the soil can liberate more calcium than magnesium, and effects noticed. The salinity of soil increased by adding more amount of sulfur, while the pH of the soil decreases because sulfur converted to sulfuric acid and sulfate ion. This process leads to the reduction of pH of soil and nutrients such as Fe, Cu, Zn, Unconverted a metallic soluble ionic state from insoluble state. Nutrients are easily available for plants and were insoluble in water.

Fate of Citric Acid Addition on Mineral Elements Availability in Calcareous Soils of Jordan Valley

“…The calcareous soils present high levels of free CaCO 3 and a high pH value, in addition to large amounts of soluble salts reduced availability of essential mineral nutrients such as Zn, Cu, Mn, Fe, B, and P that are necessary for the growth and development of crops and for quality and quantity of crops yield. Techniques include adding soluble exogenous organic acid such as citric acid (CA), sulphur powder [3][4].…”
