Impact Of Agricultural Practices On The Consumptive Water Use Of Irrigated Annual And Perennial Crops Of Northern Mexico And The U.S. Southwest., Orlando Ramirez-Valle

Open Access Theses & Dissertations

In drylands, crop water use varies considerably where high temperatures and limited water availability constraints farming activities, and irrigation planning is essential for the efficient water use and long-term sustainability of agriculture. However, despite dwindling water supplies and the looming threat of more frequent and intense droughts, low-efficient irrigation (e.g., furrow and flooding) continues to be the most widely used method for water delivery into agricultural parcels. Transitioning into more sustainable agriculture requires knowledge of the period of productive vs. unproductive crop water use during the agricultural cycle. I developed a method using satellite images for partitioning evapotranspiration (ETa) into …

Insights On The Behavior Of Nano-Copper In The Agroecosystem: Mycorrhizal Associations With Spearmint (Mentha Spicata), Suzanne Annette Apodaca

Open Access Theses & Dissertations

Nanotechnology offers significant potential benefits to our society, including the agriculture sector. With the advancement of nano-enabled agrochemicals towards sustainable and efficient agricultural practices, it is essential to address environmental issues associated with the use of nanoscale materials. The same properties that give promise to applications of nanotechnology in modern agriculture could have unintended consequences on ecosystem dynamics. A point of concern for risk management is the impact of engineered nanomaterials (ENMs) to beneficial microbial communities, which support a variety of ecosystem services.

Use of copper (Cu) products in agriculture are based on their abundance, role as a micronutrient, and …

Land Use/ Land Cover Change Patterns And Trends In Two Dryland Regions, Omar Sulaiman Belhaj

Open Access Theses & Dissertations

Development and climate change affect the environment in numerous ways and to varyingdegrees. This effect appears prominent and more influential in arid regions. Therefore, land use/ land cover in these regions experience profound changes such as plant cover decrease and extinction of some plant species. Also, land use/ land cover in these regions has critical impacts on the environment and its components, such as shrublands shrinking and losing the habitat of animal species. The degree of changes and effects reaches severe levels that become urgent to figure out the impacts and find solutions to stop or mitigate the negative consequences. …
