Abstract

One of the most important factors regarding soil and plant health is nutrient availability and fertility. Of these two factors that were mentioned available potassium is a key component. With that being said we decided that it would be beneficial to see how potassium can be traced within the soil in various locations after fertilizer is applied. There were two parts to this experiment. Part one was …

Mapping Of Non-Native Invasive Plant Species Using Remote Sensing And Gis: Assessment Of Human Impact On Kudzu (Pueraria Montana) Spread, Harshitkumar Godhasara

Scholars Week

Remote sensing methods provide tools to identify and map non-native plants. Biophysical characteristics of plants can be utilized to recognize and distinguish non-native invasive plants from other native plant species. Kudzu is an invasive plant, which causes economic loss and decreases biodiversity. Moreover, kudzu doubles emission of nitric oxide and increases ozone pollution. The impact of human activities on the spread of noxious plant species like kudzu can be assessed utilizing remote sensing and geographic information systems (GIS) tools. Kudzu spread in the USA was mapped using in situ data including the actual coordinates of kudzu sites. Geographic distribution of …

Characteristics of Soils under Common Management Practices

on Farms in Western Kentucky

River O. Dowell and Iin P. Handayani, Murray State University, Kentucky

ABSTRACT

Properly understanding the importance of soil properties and how they continuously change is a key to achieving sustainability in agriculture. This study was conducted to observe the changes of soil properties regarding common tillage systems in Kentucky. Undisturbed and disturbed soil samples were collected from Butler County, KY at depths of 0-7.5 cm and 7.5-15 cm from four sites representing the different management practices of conventional tillage, no-till, pasture, and woodlands. The samples were analyzed for …
