Abstract

Experiments were conducted to determine the effects of a bagasse vinegar application to the soil surface on the growth and nutrient uptake in ripening sugarcane when applied to the original soil surface of a field. First, we checked the effect of bagasse vinegar on the dissolution of tricalcium phosphate (Ca₃(PO₄)₂). In the presence of bagasse vinegar tricalcium phosphate was ionized thus producing phosphoric acid. The stem weight and yield of sugarcane at harvest. 100 days after application tended to be increased by applying bagasse vinegar at 1-100-fold higher concentrations. Sugar content of sugarcane was significantly increased by application of bagasse vinegar at a 100-fold higher concentration. Phosphorus and silicic acid contents of squeezing juice of sugar cane were bagasse vinegar and those contents were positively correlated with sugar contents of the juice. The results suggest that the bagasse vinegar applied to the soil surface at the ripening stage of sugarcane improves the cane quality at harvest, 100 days after application through the utilization of phosphoric acid in the soil.
