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 …
Assessing The Use Of Food Waste Biochar As A Biodynamic Plant Fertilizer, Rachel Mazac
Assessing The Use Of Food Waste Biochar As A Biodynamic Plant Fertilizer, Rachel Mazac
Departmental Honors Projects
Biochar is a charcoal-like substance produced from plant material such as food waste. Converting food waste into a useful product would mitigate environmental damage through reduced landfill inputs, reduced greenhouse gas production, and increased benefits to soils. I asked (1) if biochar improved plant growth and (2) if the effects of biochar varied among different samples of mixed food waste (batches) and between different biochar preparation times (treatments). Four independent batches of biochar were prepared with assorted, uncooked food waste collected from a university dining facility. Each batch was dried then placed in a covered ceramic pot at 260℃ for …
