In order to develop the nutrient material for growing plants, tobacco leaf debris (T.L.D) that is a residual product of cigarette processing was carbonated at about 50% of its weight and neutralized its alkalinity by nitric and phosphoric acid. This material ($T.L.D+3N-HNO_3+1N-H_3PO_4$ (10:1:1), as a consequence, contained 4.1% of nitrogen, 2.1% of phosphte, and 6.6% of potassium in value of about pH 7. It was very effective on seedling growth to apply 1 Kg of nutrient material per 110 1 of bed soil as basic dressing because of containing not only quick-acting nitrate but also slow-releasing organo-nitrogen and sufficient potassium.
