| Abstract |
Using natural composts and soil conditioners like polyvinyl acetate (PVAc) and polyvinyl alcohol (PVA) may be considered a specific management for improving the properties of soil which to be reversed productivity of crops. Two rates of rice straw composts and three forms of synthetic soil conditioners (PVAc, PVA1 and PVA2) with two rates were included in this study to evaluator their effects on some physical and chemical properties, nutritional status and yield components of both wheat and sesame crops. Field experiments were conducted in sandy soil at El-Ismailia Agriculture Research Station farm in El-Ismailia Governorate, Egypt. The institute farm is located at 30o 35' 41.9" N latitude and 32o 16' 45.8" E longitude.
Results showed that, values of saturation percent, total porosity, electric conductivity (EC) and organic matter (OM) at the two studied seasons were significantly superior but were significantly inferior for bulk density and soil reaction (pH) was affected by the application of high rate of rice straw compost in presence of high rate of PVA2. moreover, results indicated that addition of high rate of either rice straw compost or synthetic soil conditioner for soils at two seasons increase more significantly the saturation percent, total porosity, EC and OM, but significantly decreased bulk density values and soil pH. Also, the values of all studied parameters in soil have not been significantly affected by synthetic soil conditioner forms, except in case of polyvinyl alcohol of molecular medium weight (PVA2) which gave the highest responses.
Positive significant responses existed for available N, P and K in soils, yields (straw and grains or seeds) and apparent nutrients recovery efficiency (ANRE) of both wheat and sesame along with their total content of the indicated macronutrients due to the application of the same previously treatments
