Forage Species Selection For Transitional Organic Production In The Southeastern United States, Jonathan Kubesch Dec 2020

Forage Species Selection For Transitional Organic Production In The Southeastern United States, Jonathan Kubesch

Masters Theses

Despite the vast production markets for forage and organic products nationally, so far limited work has been done to develop organic forages specifically for Middle Tennessee or the mid-South in general. The present organic research field focuses on vegetable and grain production; however, forage production offers an easier transition for producers moving into certified organic agriculture. The present study seeks to evaluate several forage blends for optimizing forage production under low-input transitional organic conditions. Ideally a forage system could be tailored to the beef cattle operations of Middle Tennessee, the dominant forage consumption market in this region of the mid-South. …


Extreme Fire As A Management Tool To Combat Regime Shifts In The Range Of The Endangered American Burying Beetle, Alison K. Ludwig, Daniel R. Uden, Dirac Twidwell Apr 2020

Extreme Fire As A Management Tool To Combat Regime Shifts In The Range Of The Endangered American Burying Beetle, Alison K. Ludwig, Daniel R. Uden, Dirac Twidwell

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

This study is focused on the population of federally-endangered American burying beetles in south-central Nebraska. It is focused on changes in land cover over time and at several levels of spatial scale, and how management efforts are impacting both the beetle and a changing landscape. Our findings are applicable to a large portion of the Great Plains, which is undergoing the same shift from grassland to woodland, and to areas where the beetle is still found.

An Efficient Stocking Strategy For Grazing Replacement Heifers, Keith R. Harmoney, John R. Jaeger Jan 2020

An Efficient Stocking Strategy For Grazing Replacement Heifers, Keith R. Harmoney, John R. Jaeger

Kansas Agricultural Experiment Station Research Reports

Even though Kansas native rangelands often have steep slopes or shallow soils not con­ducive to many other uses other than livestock grazing, native rangeland and perennial grassland acres in Kansas have been declining. Cropland acreage over this same time frame has increased, and rangelands have also become more fragmented by small ranch­ettes and urbanization. Producers may be looking to increase production efficiency on a shrinking forage land base. The use of intensive early stocking (IES) is one of the most efficient stocking strategies to produce beef on rangeland acres. The IES strategy has been widely used in eastern Kansas and …

The Biofiltration Ability Of Asparagus Densiflorus To Remove Sulfur Dioxide From The Indoor Atmosphere, Rhiannon De La Rosa, Mary Savin Jan 2020

The Biofiltration Ability Of Asparagus Densiflorus To Remove Sulfur Dioxide From The Indoor Atmosphere, Rhiannon De La Rosa, Mary Savin

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Sulfur dioxide is an inorganic compound (IC) and air pollutant that causes health risks in humans. The buildup of sulfur dioxide (SO2) in enclosed indoor spaces is, therefore, a concern to human health, especially since the average person spends 90% of his/her time indoors. This study focused on decreasing SO2 concentration in a cost-effective and simple way—by using botanical biofiltration, or the uptake of pollutants by plants. Research in biofiltration has focused mostly on the remediation of volatile organic compounds (VOC). However, research has also shown that plant species that remediate VOC efficiently also have the potential for efficient IC …


Decomposition In Pasture Soil Receiving Excreta From Ruminants Fed Alfalfa Forage Diet Supplemented With Increasing Proportions Of Sericea Lespedeza Legume, Yang Kai Tang, Mary C. Savin, Dirk Philipp, Ken Coffey, Jiangchao Zhao Jan 2020

Decomposition In Pasture Soil Receiving Excreta From Ruminants Fed Alfalfa Forage Diet Supplemented With Increasing Proportions Of Sericea Lespedeza Legume, Yang Kai Tang, Mary C. Savin, Dirk Philipp, Ken Coffey, Jiangchao Zhao

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Healthy soil is fundamental to a productive pasture system as it will decompose labile organic matter and promote retention of carbon to build a stable, resistant pool of organic matter. An easy, standardized approach to measure decomposition and litter stabilization that is gaining popularity in both citizen science and research studies is the use of the Tea Bag Index. The Tea Bag Index is a relatively new method evaluating the loss of organic material in two different kinds of commercial tea bags (green tea and Rooibos tea) after burial in the soil for 90 days. The objective of this experiment …

The Agronomics Of Organically Managed Legume-Grass Mixtures For Ensiled Forage Production, Allen Wilder Jan 2020

The Agronomics Of Organically Managed Legume-Grass Mixtures For Ensiled Forage Production, Allen Wilder

Graduate College Dissertations and Theses

Legume-grass mixtures are commonly grown on livestock farms in northern New England that feed high forage diets. Such farms typically ferment stored feed into silage that can be fed throughout the year. Many legumes and grass species are available for use in temperate climates and information on the yield, forage quality, and fermentation characteristics of various legume-grass combinations would help farmers make informed decisions about species selection and optimum management for their forage programs.

One obstacle to evaluating numerous forage treatments in agronomic research is the high variability in silage dry matter content. We hypothesized that a method of artificial …


Using Modified Intensive Early Stocking For Cow/Calf Production, Keith R. Harmoney, John R. Jaeger Jan 2020

Using Modified Intensive Early Stocking For Cow/Calf Production, Keith R. Harmoney, John R. Jaeger

Kansas Agricultural Experiment Station Research Reports

Intensive early stocking (IES) was introduced nearly a half century ago in eastern Kan­sas and has since been adopted as a major management tool to increase animal produc­tion, efficiency of production, and economic return on tallgrass rangelands. These in­creases have come almost exclusively by using IES with young stocker animals. Intensive early stocking and its gains have been proven effective repeatedly in published research. A similar modified IES (MIES) system has increased production efficiency of stocker animals on western Kansas rangelands. Perennial grassland acres for cattle produc­tion, as well as cattle numbers, are declining. Using management practices that mimic the …


Effects Of Pre-Cutting Round Alfalfa Hay Bales On Forage Quality And Processing Time, W. E. Brown, E. Harms, J Heimsoth, J. Mcginnis, C. I. Vahl, B. J. Bradford, M. J. Brouk Jan 2020

Effects Of Pre-Cutting Round Alfalfa Hay Bales On Forage Quality And Processing Time, W. E. Brown, E. Harms, J Heimsoth, J. Mcginnis, C. I. Vahl, B. J. Bradford, M. J. Brouk

Kansas Agricultural Experiment Station Research Reports

Round hay balers with knives that cut the hay as it enters the baling chamber reduce the particle size upon baling, and eliminate the need for a tub grinder. The objective of this study was to evaluate the effects of a round hay baler with knives on forage quality of alfalfa hay at baling and after storage, and the effects of the processing method on nutrient composition and particle size distribution. Alfalfa hay was baled (560 M Megawide HC2, John Deere, Moline, IL) with knives every 4 inches (CUT; theo­retical length of cut) or without knives (NORM). At baling and …


Including Legumes In Bermudagrass Pastures, J. L. Moyer, L. W. Lomas Jan 2020

Including Legumes In Bermudagrass Pastures, J. L. Moyer, L. W. Lomas

Kansas Agricultural Experiment Station Research Reports

Bermudagrass is a productive forage species when intensively managed. However, it has periods of dormancy and requires proper management to maintain forage quality. Legumes in a bermudagrass sward could improve forage quality and reduce fertilizer usage; however, legumes are difficult to establish and maintain with the competitive grass. Clovers can maintain survival once established in bermudagrass sod, and may be productive enough to substitute for some N fertilization. This study was designed to compare dry cow performance on a bermudagrass pasture system that included ladino and crimson clovers (Legume) vs. bermudagrass alone (Nitrogen). Use of legumes in wheat-bermudagrass pastures did …


Association Of Horizontal Silo Pad Type, Elevation And Core Depth With Indicators Of Silo Ramp Hygiene, Forage Quality, And Digestibility, W. E. Brown, N. M. Bello, M. J. Brouk Jan 2020

Association Of Horizontal Silo Pad Type, Elevation And Core Depth With Indicators Of Silo Ramp Hygiene, Forage Quality, And Digestibility, W. E. Brown, N. M. Bello, M. J. Brouk

Kansas Agricultural Experiment Station Research Reports

Horizontal silo piles without walls are constructed using packing equipment to adequately pack the forage for air exclusion. During packing, the equipment uses a ramp of forage to access the top of the pile, potentially introducing soil into the forage when the base of the silo is made of soil. Soil contains microorganisms which may cause malfermentation and pose health risks to livestock. The objective of this study was to assess the association of horizontal silo pad type, elevation, and core depth with indicators related to silage hygiene and nutrient quality. We hypothesized that ash and mineral content, microbiological profile, …
