Short Term Shifts In Soil Nematode Food Feb Structure And Nutrient Cycling Following Sustainable Soil Management In A California Vineyard, Holly M. Deniston-Sheets
Short Term Shifts In Soil Nematode Food Feb Structure And Nutrient Cycling Following Sustainable Soil Management In A California Vineyard, Holly M. Deniston-Sheets
Master's Theses
Evaluating soil health using bioindicator organisms has been suggested as a method of analyzing the long-term sustainability of agricultural management practices. The main objective of this study was to determine the effects of vineyard management strategies on soil food web structure and function, using nematodes as bioindicators by calculating established nematode ecological indices. Three field trials were conducted in a commercial Pinot Noir vineyard in San Luis Obispo, California; the effects of (i) fertilizer type (organic and inorganic), (ii) weed management (herbicide and tillage), and (iii) cover crops (high or low water requirements) on nematode community structure, soil nutrient content, …
Compact Farms: A Step Towards Sustainability, Chad A. Porter
Compact Farms: A Step Towards Sustainability, Chad A. Porter
Agricultural Education: Graduate Internship Reports
This project report accounts for the potential benefits compact farms can have for agriculture and sustainability. The report details the design, implementation, and management of Whistle Stop Farm, a 1-acre, diverse farm producing vegetables, fruits, and gourmet mushrooms for direct markets in Atascadero, California. The farm focuses on economic and environmental sustainability. A large part of the farm revolves around soil science and how to manage soils to promote a healthy soil ecosystem.
The Effect Of Mulch Type And Thickness On The Soil Surface Evaporation Rate, Michael Mcmillen
The Effect Of Mulch Type And Thickness On The Soil Surface Evaporation Rate, Michael Mcmillen
Horticulture and Crop Science
There is a continual drive to conserve water and improve irrigation efficiency in agriculture, especially in regions where water resources are limited and regulated. Mulching is one cultural practice which can be used to reduce water needs. Using certain agricultural byproducts as mulch is a sustainable practice which can provide other benefits as well such as improving soil. Wheat straw, grass clippings, and leaf debris are fairly abundant byproducts which can be used as mulch. An experiment was conducted to determine which of these readily available mulching materials would be best at conserving soil moisture, and at which thicknesses, 5, …
A Comparison Of The Efficiency And Profitability Of Holsteins And Jerseys, Kelli Ann Carstensen
A Comparison Of The Efficiency And Profitability Of Holsteins And Jerseys, Kelli Ann Carstensen
Dairy Science
The efficiency and profitability of Holstein and Jersey cows has been scrutinized, compared, and debated for many years. In response, this study was conducted with the objective of incorporating reviews and results collected from numerous studies relating to Holstein and Jersey efficiency and profitability to determine if a breed advantage existed in any or all related areas. Articles reviewed were obtained from the Journal of Dairy Science, the New Zealand Journal of Agricultural Research, and the Journal of Dairy Research. Jerseys were found to demonstrate breed advantages in pasture systems, longevity, stayability, productive life, calving ease, reproduction, heat stress under …

World Languages and Cultures
My senior project is a combination of my major of Modern Languages and Literature and my minor in Sustainable Environments. I have tried to combine everything I learned in the following essays which explain different elements of the sustainable movement in the world. Currently there is a big push towards environmentalism which was started by a global desire to repair the damage done to our planet Earth. My goal is to explain some of the situations addressed by the sustainable movement and to propose some solutions based on what I’ve learned in my five years at Cal Poly. During my …
