The Analysis of Phosphate Ions in Tithonia diversifolia (Wild Sunflower) Used as Composite Manure

Abstract

Inorganic fertilizers have been a greater threat to soil structure and vegetables that are consumed by human being. Tithonia diversifolia is a plant that grows locally or can either be planted to be used in making of manure due to its high level of Nitrogen, potassium, and phosphates. In this research, phosphate ions were analyzed in order to ascertain the effectiveness of Tithonia diversifolia. An Ultraviolet-visible spectroscopy was used to determine the wavelength of the phosphates in Tithonia diversifolia. Baraton University research farm widely use Tithonia diversifolia when making their composite manure. The research showed that there is a significant amount of phosphates in the plant from both the sample areas. The phosphates absorbance was in the range of 0.593 to 0.777. Organic manure has therefore been widely recommended as the best to grow vegetables and even maize.
