Analysis Of Permaculture’S Water Conservation And Crop Supporting Abilities, Hannah Chaney May 2019

Analysis Of Permaculture’S Water Conservation And Crop Supporting Abilities, Hannah Chaney

Mahurin Honors College Capstone Experience/Thesis Projects

In the Middle East, virtually all agriculturally viable land is under high threat of desertification due to poor land and resource management and climate change. Mulching using straw flakes (straw mulch permaculture) is a method commonly used in successful dry land permaculture projects in the Middle East. We proposed that straw mulch permaculture would increase the amount of soil moisture during dry periods and that this method would not impact the growth and survival of the crop. In order to test this hypothesis, we took soil samples from plots with and without straw mulch permaculture in Bowling Green, KY and …
