Finding an Environmentally Safe Method to Increase Crop Respiration Rates.

Sustainable agriculture has been studied in specific areas, and this project concentrated on finding an environmentally safe method to increase crop respiration rates, pH levels (4-10) were varied in order to determine the optimal range for a set of five specific crops: Soybean, Cucumber, Garden pea, String bean, and Okra. A respirometer was used to determine the respiration rates (cc/min) for five grams of the seedlings exposed to a single pH environment. Each crop had its own specific optimal range of values for each pH. The string bean seedlings in pH 6 and pH 8 yielded the maximum values. The mean values were also calculated and plotted with standard deviations marked. Most of the crops seemed to yield the highest range of values in the slightly alkaline or slightly acidic environments.
