Abstract
This study aims to:
• Evaluate of the effect of geotextile, of natural and artificial origin on particular physical and chemical properties of sandy and clay soils, compared to compost.
• Choose the best additive method of each amendment type of geotextile under different irrigation application rates.
• Quantify the productivity of sorghum plants grown in sandy and clay soils for different treatments.
To achieve this aim, cotton, polyester and compost plus the control treatment and layer or mix application method under 50, 75 and 100% of FC were used in a pot experiment, conducted at experimental farm of Faculty of Agriculture, Menoufia University, during growing winter season of 2019 using sorghum (Panicoideae, cultivar) plants.
Furthermore, cumulative and rate of infiltration was measured, with double ring, in the open field at Quesna (representing sandy soil) and Shebin El Kom (representing clay soil). The curves and regression equations were computed using Microsoft Excel program.
After 70 days of planting, the plants of each pot (eight plants) were harvested at the soil surface. Fresh and dry weights of the harvested plants were recorded. Also, the plants contents of N, P and K were determined. After plant harvesting soil sample of surface 5 cm was taken separately from each pot and analyzed for it’s pH, EC, CEC and content of OM.
