Cropping production and tillage systems lead to loss of soil organic matter (SOM), lowering soil pH, and soil compaction in Kentucky. However, the magnitude of the changes varied among the soil properties. Therefore, the objective of this research was to evaluate the changes in SOM, soil pH, and soil compaction under different cropping systems like corn-soybean-tobacco rotation (Field #1), continuous corn field (Field #2), hemp field (Field #3), wheat field (Field #4), pasture with animal grazing (Field #5), and canola field (Field #6). The prominent soil textures in all fields are silt loam and silty clay loam. Disturbed soil samples …

The purpose of this study was to evaluate the variations of soil characteristics under different management practices in rural soils versus urban soils. In this study, soil samples from rural areas in Kentucky were collected from a woodland plot, a no-till plot, and a tilled plot. The soil samples from the rural were taken from two depths in order to better evaluate the effect of tillage on the soil. A shallow depth of 0-7cm and a deep depth of 7-15cm were used. Soil samples were also taken from urban plots in Memphis, TN. The sampled plots included were an animal …
Managing Risk In Grazing Operations, Christopher D. Teutsch, Kenneth H. Burdine
Managing Risk In Grazing Operations, Christopher D. Teutsch, Kenneth H. Burdine
Kentucky Grazing Conference
Risk is an inherent part of agricultural production systems. Crane and coworkers (2013) identified five primary areas of risk in grazing operations: 1) MARKETING risk, 2) PRODUCTION risk, 3) LEGAL risk, 4) HUMAN risk, and FINANCIAL risk. These types of risk are described in the accompanying publication entitled “Controlling Risk in Grazing-Based Production Systems” by J. Parsons. This article will discuss the risk associated with “production” in grazing systems, focusing specifically on managing drought in grass based production operations.

Turning Grass Into Cash With Small Ruminants, Kenneth Andries
Kentucky Grazing Conference
As agriculture continues to change, it is important to consider sustainability before starting or expanding any enterprise. One critical factor in any animal agriculture enterprise is controlling feeding costs. Most research indicates feeding is the largest expenses in any livestock enterprise. However, nutrition is critical to overall productivity and the income of the enterprise. Because of this, producers need to find ways to improve nutrient availability while minimizing costs to optimize production and profitability for their livestock enterprise.

Considerations For Making A Profit With Stocker Cattle, Jeff Lehmkuhler
Considerations For Making A Profit With Stocker Cattle, Jeff Lehmkuhler
Kentucky Grazing Conference
The southeast is home to more than 7.3 million beef cows (USDA 2018). At an estimated 80% weaning rate and 20% heifer retention, the southeast region would be expected to produce more than 4.6 million feeder calves that would go to market in 2018. The cow-calf industry in the region provides an opportunity for the stocker and backgrounding operations to co-exist. Much of the land in the region is best suited for forage and pasture production, which at the current moment, provides a low cost feed for adding pounds to light weight feeder cattle. Yet, the stocker and backgrounding segments …
Measuring Profitability In Grazing Operations, Kenneth H. Burdine
Measuring Profitability In Grazing Operations, Kenneth H. Burdine
Kentucky Grazing Conference
When producers make investments in extending their grazing season, they do so in order to obtain an economic benefit. These benefits usually include a reduction in the number of days that stored feed (typically hay) is fed, an increase in carry capacity or stocking rate, or an increase in production level (rates of gain, weaning weights, etc). While all of these are potential benefits of improved grazing systems, a reduction in winter feeding days is often the simplest way to start. When the grazing season is extended, winter feeding days are reduced, and this cost savings can be weighed against …

Remote Sensing Using I-Band And S-Band Signals Of Opportunity, Kadir Efecik, Benjamin R. Nold, James L. Garrison
The Summer Undergraduate Research Fellowship (SURF) Symposium
Measurement of soil moisture, especially the root zone soil moisture, is important in agriculture, meteorology, and hydrology. Root zone soil moisture is concerned with the first meter down the soil. Active and passive remote sensing methods used today utilizing L-band(1-2GHz) are physically limited to a sensing depth of about 5 cm or less. To remotely sense the soil moisture in the deeper parts of the soil, the frequency should be lowered. Lower frequencies cannot be used in active spaceborne instruments because of their need for larger antennas, radio frequency interference (RFI), and frequency spectrum allocations. Ground-based passive remote sensing using …
A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum
A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum
Celebration of Learning
Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic …

The Effects Of Time And Topography On Deep Carbon Storage In The Clarks River Valley Of Western Kentucky, Benedict W. Ferguson
Scholars Week
Soil organic carbon (SOC) dynamics at depths greater than one meter in valley bottoms are not well understood. This study examines the stock of SOC with depth across alluvial landforms in the Clarks River National Wildlife Refuge. Nine cores along three transects from terraces to floodplains and adjacent channel bars were collected to depths of 4 meters or refusal. Bulk density, clay content, and loss-on-ignition were used to estimate stocks. Age estimates based on radiocarbon suggest the landforms range in age from 7975 to 52 yr BP. Average SOC and carbon (C) flux varied with values of 1.76 kg/m2 …

Integrated Management Of Alfalfa Diseases, Kiersten A. Wise
Integrated Management Of Alfalfa Diseases, Kiersten A. Wise
Kentucky Alfalfa and Stored Forage Conference
Alfalfa diseases can reduce forage quality and the longevity of alfalfa stands. Integrated management of diseases can minimize disease impact and improve forage stand and quality. There are several important pathogens that cause disease on alfalfa, and the occurrence of these diseases, as well as the severity of damage, depend on several factors, including the type of pathogen, the environment, and the level of resistance of the host to a particular disease. In addition, disease presence and severity are also influenced by agronomic practices, particularly sowing dates, cutting dates and frequency, and fertility programs.

An Integrated Pest Management Ipm Approach In Alfalfa Production Systems, Lee H. Townsend
Kentucky Alfalfa and Stored Forage Conference
Alfalfa lends itself to an integrated pest management (IPM) approach for alfalfa weevils and potato leafhoppers, the two key insect pests of the crop. Both species live in most alfalfa fields every summer. However, alfalfa can tolerate low levels of their feeding without costly yield or quality loss.
An Integrated Approach To Weed Control In Alfalfa Production Systems, Jonathan D. Green
An Integrated Approach To Weed Control In Alfalfa Production Systems, Jonathan D. Green
Kentucky Alfalfa and Stored Forage Conference
The importance of weed control in forage production should not be overlooked, especially when you consider the high investment associated with alfalfa and other legume forages. Weeds reduce forage yield by competing for water, sunlight, and nutrients. For example, yield obtained from the first cutting of alfalfa can be significantly reduced by a heavy infestation of common chickweed. In addition to yield losses, weeds can also lower forage quality, increase the incidence of disease and insect problems, cause premature stand loss, and create harvesting problems. Some weeds are unpalatable to livestock or, in some cases, may be poisonous.

Alfalfa Establishment: Getting Off To A Good Start!, Christopher D. Teutsch
Kentucky Alfalfa and Stored Forage Conference
Alfalfa is a highly productive forage legume that is well adapted to transition zone states like Kentucky. It can be grazed, hayed, or ensiled. Once established and under good management, expected yields range from 5-7 tons per acre per year. High yields can only be obtained from a dense and vigorous alfalfa stand. The first step in obtaining such stands is establishment. The establishment phase of alfalfa production is critical since realization of returns from all other input costs is dependent upon having a good stand and it is expensive. It is important to remember that alfalfa establishment begins long …
