Abstract

This research work was conducted at the Agricultural Scientific Research Center in Tartous, GCSAR in the summer of 2016 to study the ability of using wood coal ash in composting of tobacco residues. The study included four experimental treatments, consisting of a control (tobacco residues with calcium carbonate without ash), and three other concentrations of ash (10, 15 and 20%). The complete randomization design was followed and based on three replicates per treatment. The results showed that compost’s  pH increased from 7.76 to 8.21, C/N from 17.44 to 19.61 and calcium content from 1.31% to 1.6% with the increase in the concentration of ash, and the treatment (20%) of ash increased P and K contents in the compost (0.475% and 1.46%) respectively, while the addition of ash to the residues of tobacco caused a decrease in the content of the produced compost of nitrogen and magnesium.

Key words: Tobacco residues, Compost, Ash, Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, C/N.
