Résumé partiel
Laboratory and field experiments were carried out to clarify the impact of different types of natural and synthetic polymers on some hydrophysical properties (soil hydraulic parameters) of a sandy soil beside potatoes characters and yield. Because of the great importance of hydraulic polymers, a group of natural, industrial and synthetic polymers have been used and synthesized, where a polymer that has all the properties of sponge (hydrophobic) or superabsorbent polymers has been manufactured using some natural materials such as wastes from corn and wheat factories and screening stations, where these raw materials containing polymers were used. Cellulose, proteinuria, and lipid chains in the reconstruction of a type of semi-polar polymer, and this polymer was named (MUSA1). Adding 0.5% (w/w) of each treatment to soil significantly increased water retention at saturation, field capacity, total available water, and readily available water. This treatment decreased the value of the inflection point on the water retention curve as a result of enhancing water behavior in the soil. The obtained results revealed that soil water storage significantly increased from 0.271 in the control treatment (without adding polymer) up to 0.414 in treatment [T10] (Acrylic acid + Xanthan) while, field capacity significantly increased from 0.078 in control up to 0.242 for the abovementioned treatment(T10). Regarding the effects of polymer application in total available water and readily available water, data revealed significant increases in the above-mentioned parameters. Total available water increased from 0.044 in control treatment up to 0.153 in T10 and readily available water increased from 0.057 in control treatment up to 0.185 in T10.
