Effectiveness Of Windrow Composting Methodology In Killing A Thermo-Tolerant Species Of Salmonella During Mortality Composting, Spencer Gabriel Myers Feb 2019

Effectiveness Of Windrow Composting Methodology In Killing A Thermo-Tolerant Species Of Salmonella During Mortality Composting, Spencer Gabriel Myers

Master's Theses and Project Reports

In a large agricultural operation, such as the one at Cal Poly San Luis Obispo, disposal of deceased animals is an immense issue. The cost of transporting and rendering every dead animal is inhibitory to the general function of the agricultural operations and their thin budget. Therefore, we propose that composting mortalities could be an economical alternative. Composting is a recognized method for taking animal waste products along with carbon waste and turning it into a pathogen-free, nutrient-rich topsoil. Carcass composting is in fact performed in other countries and states to varying degrees of success. However, the California EPA limits ...


Agriculture In The Classroom Farm Day Lesson Plan, Tessa Nicole Thompson Mar 2018

Agriculture In The Classroom Farm Day Lesson Plan, Tessa Nicole Thompson

Agricultural Education and Communication

Nontraditional educational programs have been proclaimed desirable by many teachers, and proven effective through data collection and feedback (Coombs and Ahmed, 1974). Of the more popular unconventional educational programs, outside learning activities are commonly implemented as they are not only advantageous to students, but to teachers as well (Cengelci, 2013; Knoblock, 2008). Though nontraditional, much thought must be put into creating lesson plans for these educational programs.

El Dorado County’s Agriculture in the Classroom program utilizes nontraditional outdoor learning activities to conduct “Farm Day.” This lesson plan, created for Farm Day, is to teach third graders the importance of ...

ABSTRACT

Effects of Compost, Legume Cover Cropping and Vermicompost Extract Foliar Applications on Nutrition and Yield of Washington Navel Oranges

William Payton Carling

An experiment was conducted to test the effects of four treatments on Washington navel orange (Citrus sinensis) trees in regards to nutrient content of the leaves and fruit, soil nutrient content and properties, and fruit yield. The four treatments included: compost (C) and vermicompost extract foliar (VEF) applications, legume cover cropping (LCC) and VEF applications, VEF applications, and a control. The treatments were implemented from February 2010 to April 2011 and sampling occurred in May 2011. Fruit ...


Factors Affecting The Reduction Of Carbon To Nitrogen Ratio In Composted Separated Solids, Mark Fagundes Mar 2012

Factors Affecting The Reduction Of Carbon To Nitrogen Ratio In Composted Separated Solids, Mark Fagundes

Dairy Science

The objective of the study was to determine the factors involved in the reduction of carbon to nitrogen ratio in composted separated solids. A single compost windrow was laid on a 6,000 jersey cow dairy farm located in Madera County. Samples were obtained from six separate positions on the pile, every other day. Direct pile measurements on the date of sampling included pile temperature (surface and core), height, width and curvature. Samples were removed from the windrow during each sampling meeting to determine the percent dry matter content. The collected samples were sent out to Denele Analytical Inc. to ...
