The Design, Construction, And Testing Of An In-Furrow Planter For The Planting Of Low Residue Cover Crops, Chandler A. Bennett Mar 2014

The Design, Construction, And Testing Of An In-Furrow Planter For The Planting Of Low Residue Cover Crops, Chandler A. Bennett

BioResource and Agricultural Engineering

This project encompasses the design, construction, and evaluation of an in-furrow planter for the planting of low residue cover crops. The purpose of planting the furrow is for the management of off-site removal of residual pesticides, nutrients, and soil by mitigating water flow. Due to there being no current solution for the mechanized planting of furrows this project was pursued to provide a means for farmers to do so at the most cost effective means. The result of this project is a prototype planter that can be made with basic shop tools, be made with off the shelf parts, and …


Evaluating Sampling Strategies For Rainfall Simulation Studies And Surface Transport Of Antibiotics From Swine Manure Applied To Fescue Plots, Holly K. Enlow Jan 2014

Evaluating Sampling Strategies For Rainfall Simulation Studies And Surface Transport Of Antibiotics From Swine Manure Applied To Fescue Plots, Holly K. Enlow

Theses and Dissertations--Biosystems and Agricultural Engineering

Antibiotics are commonly used in animal agriculture to treat and prevent diseases and promote growth. Unfortunately, large amounts of antibiotics are not metabolized, but instead are excreted in urine and feces. Rainfall simulation studies were used to investigate the transport of the antibiotic oxytetracycline and various constituents in runoff and the ability of alum to reduce pollutant transport. Runoff samples were collected at several points during the simulated storm event from each of four treatments: control (C), manure only (M), manure and antibiotics (MA), and manure, antibiotics and alum (MAA). Flow-weighted composite samples were created and compared to the flow …
