Abstract:
Three replicates of each treatment were used to study the effects on various physical and chemical properties, including bulk density, porosity, main weight diameter, and aggregate size distribution. Four levels of tobacco west compost (0,10,20, and 30 tons/h) were added to the clay soil treatment, and plant foliar spray (0,2,4 ml/l) was applied in three concentrations of compost filtrated extract.The results showed that tobacco wast compost (K1, K2, K3) was effective in increasing the soil content of organic matter (29,58,66%) compared to the control. The treatment ameliorates as well the soil’s physical properties, main weight diameter, stable aggregate, and soil porosity. Whereas bulk density decreased, soil nitrogen, potassium, and phosphorus content increased significantly compared to the control in the three treatments. The results showed as well that foliar application of compost extract alone or with compost has no effect on soil properties. Plant growth metrics significantly increased when the soil was treated with tobacco waste compost and its extract, with 30 tan/h + 4 ml of extract yielding the best values
