Sustainable Production Of Bioenergy From Agricultural And Food Waste, Stéphanie Jung Jan 2014

Sustainable Production Of Bioenergy From Agricultural And Food Waste, Stéphanie Jung

Leopold Center Completed Grant Reports

This project will determine the potential of pre- and post-consumer waste collected from ISU Dining for bioethanol production. The investigator will gather data about the quantity and composition of these wastes and how much energy could be produced.


The Extent And Impact Of Trust Ownership On The Sustainability And Resiliency Of Iowa’S Agricultural Landscape, Edward Cox, Michael Duffy Jan 2014

The Extent And Impact Of Trust Ownership On The Sustainability And Resiliency Of Iowa’S Agricultural Landscape, Edward Cox, Michael Duffy

Leopold Center Completed Grant Reports

The popularity of trusts as a land management tactic has been increasing. Using survey results, an attorney and economics professor examined the kinds of trust arrangements that exist in Iowa and how they might be used to encourage conservation practices and sustainable agricultural management.


Developing Permaculture Techniques For Increased Production And Profit In Sustainable Year-Round Agriculture For Beginning Farmers And Ranchers In Southwest Iowa, Greg Mathis, Michelle Wodtke Franks Jan 2014

Developing Permaculture Techniques For Increased Production And Profit In Sustainable Year-Round Agriculture For Beginning Farmers And Ranchers In Southwest Iowa, Greg Mathis, Michelle Wodtke Franks

Leopold Center Completed Grant Reports

The project participants researched, developed, tested and implemented technologies for year-round growing seasons designed to be viable under the growing conditions in southwest Iowa. High tunnels, alternative crops, vermiculture and collaborative producer groups were among the options tested.


Building Social Networks To Capture Synergies In Wood-Based Energy Production And Invasive Pest Mitigation, Jesse Randall, Tricia G. Knoot, John Tyndall Jan 2014

Building Social Networks To Capture Synergies In Wood-Based Energy Production And Invasive Pest Mitigation, Jesse Randall, Tricia G. Knoot, John Tyndall

Leopold Center Completed Grant Reports

This project makes a variety of policy recommendations for cities and the private sector to help deal with the consequences of emerald ash borer infestations.


Understanding Soil Organic Matter Change: Modeling Root And Soil Interactions Across Agricultural Landscapes, Cynthia A. Cambardella, Todd A. Ontl, Lisa A. Schulte Moore, Randall K. Kolka Jan 2014

Understanding Soil Organic Matter Change: Modeling Root And Soil Interactions Across Agricultural Landscapes, Cynthia A. Cambardella, Todd A. Ontl, Lisa A. Schulte Moore, Randall K. Kolka

Leopold Center Completed Grant Reports

What are some options for enhancing organic content and carbon storage in soils that have been used in intensive row-crop production? The project looked at bioenergy feedstocks and how they might be employed to improve soil properties.


Transitioning To Ecologically Functional Production Systems, Kirsten S. Hofmockel, Lisa A. Schulte Moore, Thomas M. Isenhart, Randall K. Kolka Jan 2014

Transitioning To Ecologically Functional Production Systems, Kirsten S. Hofmockel, Lisa A. Schulte Moore, Thomas M. Isenhart, Randall K. Kolka

Leopold Center Completed Grant Reports

A gap in transitioning to ecologically beneficial farming practices is the lack of understanding of how soils store carbon (C) and nitrogen (N)long term. Farmers need management practices for improving soil quality, increasing both belowground (live roots) and aboveground (live cover) biomass, increasing soil organic matter, and reducing greenhouse gas emissions. This project quantified root productivity, root decomposition, soil microbial dynamics, soil aggregation, and belowground C allocation in annual and perennial biomass cropping systems across multiple landscape positions.


Column Study To Access Bioretention Cell Filter Mixtures For Urban Stormwater Management, Sally D. Logsdon, Pat Sauer Jan 2014

Column Study To Access Bioretention Cell Filter Mixtures For Urban Stormwater Management, Sally D. Logsdon, Pat Sauer

Leopold Center Completed Grant Reports

The study examined several options for material mixtures in bioretention cells to keep water cleaner and cut down on pollution into urban storm sewers.


Comparison Of Biofuel Systems (Cobs) Project: Biomass Energy Conversion And Energy Return On Investment Analyses For 2012 Growing Season, Fernando E. Miguez, Virginia Nichols Jan 2014

Comparison Of Biofuel Systems (Cobs) Project: Biomass Energy Conversion And Energy Return On Investment Analyses For 2012 Growing Season, Fernando E. Miguez, Virginia Nichols

Leopold Center Completed Grant Reports

From 2009-2012 the COBS team used a standard method to estimate carbohydrates in the biomass harvested from the biofuel systems in order to determine the cellulosic yields. This project performed the same analysis for 2012 harvested biomass, and further analyzed biomass from 2009-2012 using a method that is less commonly used due to its expense, but is much more accurate.
