Responses Of Soil Carbon Sequestration To Climate-Smart Agriculture Practices: A Meta-Analysis, Xiongxiong Bai, Yawen Huang, Wei Ren, Mark Coyne, Pierre-Andre Jacinthe, Bo Tao, Dafeng Hui, Jian Yang, Chris Matocha

Biology Faculty Research

Climate-smart agriculture (CSA) management practices (e.g., conservation tillage, cover crops, and biochar applications) have been widely adopted to enhance soil organic carbon (SOC) sequestration and to reduce greenhouse gas emissions while ensuring crop productivity. However, current measurements regarding the influences of CSA management practices on SOC sequestration diverge widely, making it difficult to derive conclusions about individual and combined CSA management effects and bringing large uncertainties in quantifying the potential of the agricultural sector to mitigate climate change. We conducted a meta-analysis of 3,049 paired measurements from 417 peer-reviewed articles to examine the effects of three common CSA management practices …

Nebraska Strong - Social Capital In Action, Marilyn R. Schlake

Cornhusker Economics

We have heard it and we have witnessed it in action. Nebraska Strong has been a unifying message that is bringing Nebraskans, friends and family together from across the nation. Signifying strength, determination, and a resolve to rebuild, Nebraska Strong has bolstered communities and individuals who have, in some cases, lost all semblance of what they had prior to the disastrous March blizzard and floods. Through this simple message, individuals have begun to utilize their social group networks or social capital to support recovery efforts.

Through the study of communities that have experienced major disasters, researchers found the existence of …

Measurement Of Heavy Metals And Enzyme Activities In The Wetlands Of The Moreau River, William Doggett

Show Your Stripes Research and Creative Showcase

Research has indicated that the use of animal manure as fertilizer is a significant point source of pollution to the environment. Heavy metals can be found in and from items such as cigarettes, construction sites, mining areas, and some over-the-counter medications. The use of these items can cause serious health effects on humans and the environment. Through surface runoff, the heavy metals are transported to the wetlands causing pollution. The sensitivity of enzymes to the environmental pollution, the ease of assay, and their role in soil biological functions makes them useful tool as indicator of soil quality. The objectives of …

Cover Crops As Tools: How Soil Fungal Communities Can Be Prepared For Successful Prairie Restoration, Andrew Allee, Blake Branch

Show Your Stripes Research and Creative Showcase

Arbuscular mycorrhizal fungi (AMF) have major impact on plant survival, growth and plant community structure. Current land management practices utilize tilled corn-soybean rotations prior to restoration to control exotic weeds. Here, we investigate whether incorporating no-till practices and different cover crop combinations prior to prairie planting provide a more robust prairie restoration. Measuring fungal community changes occurring in old and conventional fields in comparison to a remnant prairie, we found that community composition of all fields was distinct. AMF richness differed among fields, but diversity did not. We will continue to monitor fungal community composition annually, measuring how cover crop …

Abiotic Stress And Anthocyanins Biosynthesis In Arabidopsis Thaliana, Carolanne Bekus

Student Scholar Showcase

Crops and farmers today are facing unprecedented challenges due to the changing environment. The plants of the future need to be hardy to survive harsh environmental conditions such as increased temperature, and prolonged droughts. It is imperative to understand the mechanisms plants employ to protect themselves under these types of stresses. Anthocyanins are pigments of the flavonoid subclass produced by plants. They impart red to purple color to flowers, fruits, and seeds. They also have antioxidant properties and they contribute to stress tolerance in plants. They are understood to be produced under abiotic stresses in order to protect the plant. …

The Impact Of Different Data Processing Methods On Site-Specific Management Recommendation, Taro Mieno, Joe D. Luck, Zhengzheng Gao

Cornhusker Economics

Precision agriculture has the potential to enhance farming profitability substantially via site-specific management of fields. One of the promising ways of generating such profitability-enhancing input is to a use recommendation map is on-farm randomized trials. The process of generating an input (say nitrogen) using a recommendation map typically involves the following steps:

1. Design and implement randomized input use trial

2. Collect yield data along with other field characteristics (Slope, Electrical Conductivity, and Organic Matter)

3. Process the data for statistical analysis

4. Conduct regression analysis to estimate production function (how the input affect crop yield)

5. For each of …

Sustainability Of Organic Soil Amendments On Soil Fertility And Earthworms, Mackenzie Hoffman

Scholars Week

One of the growing concerns of farmers is soil fertility which is defined as the ability of soil to grow and support plant life by minerals and nutrients needed for the plants. Healthy soil leads to better yields which lead to more food produced. Traditionally, soil fertility has been maintained with the use of chemical fertilizers. This research looked at an alternative method of increasing soil fertility: the addition of a soil amendment. Chemical fertilizers can lead to an oversupply of nitrogen which can make the plants more susceptible to diseases and pests and can also reduce the colonization of …

The Role Of Insured Bushels And Pre-Harvest Hedging For An Eastern Nebraska County Under Rain-Fed Growing Conditions, Cory Walters, Richard Preston

Cornhusker Economics

At the beginning of the crop year crop producers face unknown yields and prices resulting in a large range of end of season (fall) net income. Producers can chose to participate in risk management tools, resulting in a reshaping of the fall net income distribution. Two of the most common tools are crop insurance and pre-harvest hedging (hereafter referred to as hedging). The most common crop insurance policy sold today is Revenue Protection (RP) where both yield and prices are insured. RP policy represents an intriguing crop insurance contract since it not only insures against price declines between spring and …

Co2 Flux And C Balance Due To The Replacement Of Bare Soil With Agro-Ecological Service Crops In Mediterranean Environment, Emanuele Radicetti, O. Adewale Osipitan, Ali Reza Safahani Langeroodi, Sara Marinari, Roberto Mancinelli

Haskell Agricultural Laboratory (Northeast Research and Extension Center)

Intensive agriculture practices often results in decomposition of organic matter, thus causing soil CO₂ emissions. Agro-ecological service crop could be profitably cultivated to improve soil characteristics and reduce CO₂ emissions under Mediterranean environment. Two-year field trials were conducted in central Italy. The treatments were three agro-ecological service crops (hairy vetch, oat, and oilseed rape) and a no-service cover. Plant development, soil characteristics, and CO₂ emissions were measured. Oat and oilseed rape showed a rapid growth, while hairy vetch started to grow rapidly only after the cold period. Soil CO₂ emissions trend was similar among the agro-ecological …

Diversity Of Nitrogen Fixing Bacteria In A Sample Aquaponics Ecosystem, Joshua Trombley, Haley Depner

Thinking Matters Symposium Archive

In natural ecosystems, nitrogen-fixing bacteria act as the primary source of useable nitrogen for many plants by converting atmospheric N2 into ammonia. In an aquaponics system, however, the primary source of ammonia is provided by fish waste. We are investigating the effect of this ammonia saturation on the diversity of nitrogen-fixing bacteria in a sample aquaponics system. We seek to answer two fundamental questions: First, what nitrogen fixing microbes are present in these systems? Second, does the character of these microbial communities have any effect on plant growth? In order to answer these questions, we first determine whether nitrogen-fixing bacteria …

Chemical Amendments Of Dryland Saline–Sodic Soils Did Not Enhance Productivity And Soil Health In Fields Without Effective Drainage, Girma A. Birru, David E. Clay, Thomas M. Desutter, Cheryl L. Reese, Ann C. Kennedy, Sharon A. Clay, Stephanie A. Bruggeman, Rachel K. Owen, Douglas D. Malo

Agronomy, Horticulture and Plant Science Faculty Publications

A common restoration treatment for saline–sodic soils involves improving soil drainage, applying soil amendments (e.g., CaSO₄, CaCl₂, or elemental S), and leaching with water that has a relatively low electrical conductivity. However, due to high subsoil bulk densities and low drainable porosities, these treatments many not be effective in glaciated dryland systems. A 3-yr field study conducted in three model systems determined the impact of chemical amendments (none, CaCl₂, CaSO₄, and elemental S) on plant growth, microbial composition, temporal changes in electrical conductivity (EC_e ), and the relative sodium content (%Na). …

Distribution Of The Aquaponics Microbiome And Their Division Of Labor, Nathan Melo, Jacob Corney

Thinking Matters Symposium Archive

Farming practices have always been labor intensive and required a great deal of resources including space, nutrients, heavy equipment, and a great deal care. Hydroponics sought to remedy this with its space saving, small scale-high yield strategy. However, this brought problems of a more sensitive system that requires constant testing and regulation of chemicals and minerals. The addition of an organic fertilizer from fish and filtration system comprised of a community of microbes reduces the taxing rituals of aquaponics and recategorizes the system as Aquaponics. In aquaponics, the plants receive their nitrogen from a the ammonia produced by fish in …

The Phytoremediative Effects Of Coriandrum Sativum In Lead Contaminated Soil, Sierra D. Garrett, Timothy Trott

Research in Biology

Environmental exposure to heavy metals such as lead pose a significant health threat. The goal of this project was to evaluate the effectiveness of Coriandrum sativum (Cilantro) as a potential lead (II), Pb²⁺, phytoremediator. C. sativumplants were allowed to grow for 43 days while exposed to with different amounts of lead nitrate, Pb(NO₃)₂. Lead exposure was accomplished by regular watering with a concentration series of lead nitrate solutions. The roots and shoots of these plants were separated and dried. Ground plant material was liquefied by nitric acid digestion. The amount of lead absorbed …

Pittsburg State University Goes Native: A Study On The Resources And Wildlife Attraction Of A Native Pollinator Garden On A College Campus, Morgan Smith, Christine Brodsky

Posters

Native pollinator gardens benefit urban communities by promoting pollination and providing support for native biodiversity conservation. Urban green spaces encourage social and physical activity, promote education, and positively influence public health in urban dwellers. Many studies have been conducted in order to fully under­stand the importance of native species reintroduction. The continuous research in this area of urban ecology can lead to better conservation and sustainability practices. This paper examines what kind of resources (i.e. costs, plants, area) are required to create a pollinator/native garden on a college campus and what kind of wildlife can be attracted by the implementation …
