Abstract
Detritus, dead organic matter, is an essential part of nutrient cycling in Earth’s ecosystems. If dead organic matter could not be decomposed, dead matter would be amassed everywhere, and its nutrients could not be returned to the soil to nourish living species. Detritivores decompose this dead matter and return its nutrients to the soil. How quickly matter decomposes is influenced by a variety of abiotic factors. One abiotic factor which is of interest to decomposition is water quantity and frequency. This study aimed to test if Baptisia australis decomposes faster in dry or wet conditions. The expected results are that the wet litterbags would have increased rates of decomposition compared to the control. Plant material was separated into 16 litter bags, weighed, and placed outside on the green roof. One group of litter bags was defined as the control in which environmental conditions were not altered; the other bags received 500mL of water biweekly. The results showed that there is no difference in decomposition related to the water frequency and quantity. Detritivores require moisture to live, so it is logical that they would be more active for decomposers in damp environments. However, that was not supported in this study. While decomposition rates are impacted by a variety of abiotic and biotic factors, the quantity and frequency of water do not seem to be an essential factor.
