| Abstract | ||||
| A pot experiment was carried out during the early winter of 2016-2017 at the Experimental Farm of Faculty of Environmental Agricultural Sciences, Arish University, to evaluate the use of some soil conditioners on physical and chemical properties of Arish sandy soil, Wheat (Triticum aestivum L.,CV Sakha 94) plants were grown in pots, A surface sandy soil sample (0-15cm) from the Experimental Farm of the Faculty was used in the study. Each conditioner was homogenously distributed on the soil surface and then were mixed with the upper 15 cm of soil surface. Grains of wheat were sown in each pot containing 20 Kg soil. NPK fertilizers were added as recommended. Vinasse, humic acid and polyacrylamide were added at three rates (0.5,1.0 and1.5(W/W)). The experimental design was complete randomized with four replicates for each treatment. Results of pH showed that the effect of applied both vinasse and humic acid to the soil in different rates led to slightly decrease on pH values gradually by increasing the rate of application. The result of acrylamide polymer show that the effect of the application to the soil led to increase pH values gradually by increasing the rate of application. Results of EC in soil show that the effect of applied vinasse, humic acid and acrylamide polymer to the soil in different rates led to increase on EC values gradually by increasing the rate of application. Also, data showed an increase in available N, P and K at all application, the higher value of N observed on application of vinasse on rates of V2 at the initial soil sampling periods, V3 at the mid-season and harvesting soil sampling periods. The higher value of P observed on application of vinasse on rates V3 at the initial soil sampling periods and HA3 at the mid-season and harvesting soil sampling periods and the higher value of K observed with application of V3 at all experiment periods. Except vinasse treatments, the mean values of organic matter, significantly increased with increasing the rates of the application the higher value HA3. Also, data indicate that for all studied levels of vinasse significantly increase soil organic matter values comparing to control treatments, HA3 achieve the highest increasing values of OM while application of PAM3 treatment was the superior for increasing soil OM. All studied levels of vinasse significantly increased soil bulk density. Apparently, HA2 and HA3 achieved the highest reducing values of BD. Such decreases represent about 8.05% and 7.89% lower than control treatment for the previously mentioned two HA rates and PAM3 treatment was the superior to other PAM3 for reducing soil BD, such decrease was 0.13 Mg m-3at the development stage of soil sampling and represent about 8.87% lower than control treatment. Results also revealed that there was a pronounced decreasing in soil Ks at the Initial period of soil sampling. Soil moisture content in both field capacity and witting point were increase along most of the studied soil sampling stages. The highest N, P and K content in grains was found for addition V3. Also, the highest grains yield was found for addition (vinasse)V3 while the control treatment had the lowest values. | ||||
