Stratification Of Potassium And Phosphorus In Tillage Vs. No-Till Systems And Uptake In Corn (Zea Mays) In Western Kentucky, Ava Isaacs, Kyle Krieger, Christopher Powell

Scholars Week

There are 12 nutrients essential for plant growth, two of these are phosphorus and potassium. The demand and need for these nutrients are very high in agricultural systems including corn. Phosphorus stimulates root and shoot growth and is essential for seedling growth and stability. Potassium increases tolerance to water stress, as well as resistance to disease, these are both critical in terms of soil fertility and in determining what fertilizers to apply as well as the amount of fertilizer needed. Both nutrients are not readily available for plant uptake in the soil and are largely lost during harvest, which could …

Linking Soil Properties to Originally Wooded and Afforested Areas

Matthew Laun, Ashton Crowe

Mentor: I. P. Handayani

Hutson School of Agriculture Murray State University, KY, USA

Abstract

Afforestation, adding an artificial forest to a piece of land that has been barren of trees for a significant amount of time, has some seriously huge impacts on the environment. These effects can be seen as an increase in the soil organic matter, a decrease in compaction, and enhancement of porosity. Therefore, the soil can support more diverse microbes and fungal communities leading to better micro and macro nutrient transfers between plants. This …


Biological Remediation Of Fragipan, Corey Hale Dec 2022

Biological Remediation Of Fragipan, Corey Hale

Honors College Theses

The fragipan layer in the soil is a naturally occurring subsurface layer that restricts water percolation as well as inhibits root growth. A fragipan layer can be found almost ubiquitously across Southwestern Kentucky. This limits how agriculturalists manage soils in this area. It has been recently discovered by the University of Kentucky that Annual Ryegrass roots produce 3,4 dihydroxyphenylpropionic acid (DHPPA) that reacts with this hardpan to weaken the layer. Certain bacteria, such as Escherichia coli, Lactobacilli, and Bifidobacteria can also synthesize DHPPA through a breakdown process of chlorogenic acid. This reaction typically happens in the human digestive tract. …

Effect Of Organic Soil Amendment On Hemp, Mounica Talasila Jan 2020

Effect Of Organic Soil Amendment On Hemp, Mounica Talasila

Murray State Theses and Dissertations

The research study is about the impact of different levels of organic soil amendment on the levels of psychoactive compounds produced in industrial hemp. Inorganic or chemical pesticides or fertilizers are not as extensively used in hemp as in other crops. Apart from this, using an organic soil amendment would be an environmentally sustainable way. A randomized block design (RBD) model was used to study the impacts of the soil amendment. The soil amendment used is called “Rehab” a product of Organilock created from the remnants of animals like fish and chicken. This research design has 3 different soil amendment …

Nature is equipped with all the right systems and services in order to be self sustaining. But in the global flower industry, growers are battling insect infestations like never before because of stricter import laws by the United States Department of Agriculture. In order to ensure the processing of their flowers, growers douse them in pesticides making them inedible and harmful to those who work with them. As edible flowers are making their way into the market on cakes and desserts, fresh salads, specialty spreads and much more it's imperative that they are grown in a sustainable and safe manner. …


Soil Responses To Various Farming Systems In Western Kentucky, Samantha Peterson Apr 2019

Soil Responses To Various Farming Systems In Western Kentucky, Samantha Peterson

Scholars Week

The interactions among the farming systems and the soil, water, biota, and atmosphere control the effects of cultivation on soil properties. Land conversion from forest or pasture ecosystems into crop fields altered soil properties due to the loss of soil organic matter (SOM) and the increase of soil compaction. However in Kentucky, the magnitude of the changes varied among the soil properties. Therefore, the objective of this research was to investigate the changes of selected soil properties include SOM, soil pH, and compaction under different crop fields such as corn-soybean-tobacco rotation (Field #1), continuous corn field (Field #2), hemp field …

Posters-at-the-Capitol

Aquaponics is a sustainable food production system that combines hydroponic plant growth with fish rearing in a recirculating aquaculture system. Nile tilapia (Oreochromis niloticus) are predominantly raised in aquaponics due to their fast growth rates and ability to tolerate a variety of water conditions. As aquaponics becomes more popular in temperate climate zones, farmers are looking for alternative fish species that are more compatible with cooler temperatures and have a higher market value than tilapia. Authors will determine if plant growth factors as well as, the availability of nutrients in aquaponic systems are affected by the difference in nutrient requirements …
