Microbial Degradation Of Urea Oligomers: Potential Slow Release Nitrogen Fertilizers, Maddy Bygd
Microbial Degradation Of Urea Oligomers: Potential Slow Release Nitrogen Fertilizers, Maddy Bygd
Departmental Honors Projects
Urea is the most commonly used nitrogen compound in fertilizers across the world. It provides the most nitrogen at the lowest cost. However, with the size and solubility of this compound, it is easily washed out of the soil. This results in the need to continuously add fertilizer to fields, creating adverse effects on the environment due to nitrogen runoff and leading to increased expenses for farmers. Triuret, a urea oligomer, is a compound with promising potential for use as a nitrogen source, providing a slower release of nitrogen into the soil. It is hypothesized that this compound can be …

To achieve high yields, corn fields are supplemented with nitrogen fertilizers. Nitrogen fertilizers account for a significant portion of production costs, and are harmful to the environment. Gluconacetobacter diazotrophicus, an endophytic nitrogen-fixing bacterium supplies its natural host sugarcane with a significant amount of nitrogen. This study investigated the colonization of G. diazotrophicus in seven different corn genotypes consisting of sweet and grain corn via three different methods of inoculation: soil drench, root dip, and aseptic inoculation. Sucrose content of the corn genotypes and nitrogenase activity were also analysed. Colonization was confirmed by PCR analysis. G. diazotrophicus colonization was detected using …
