Composting swine slurries has several advantages, liquid slurries are converted to solids at lower moisture, the total volume and weight of material is reduced and the stabilized product is more easily transported off-site. Despite this, swine waste is generally stored, treated and applied in its liquid form. High-rise finishing facilities (HRFF) permit liquid slurries to be converted to solids which are partially decomposed underneath the HRFF and then finished in compost windrows. The purpose of this study was to evaluate the effect of turning frequency and ambient weather conditions on biological, physical and chemical properties of composted slurry-woodchip mixtures from …

This article charts the progress of CenUSA Bioenergy, a USDA-NIFA-AFRI coordinated agricultural project focused on the North Central region of the US. CenUSA’s vision is to develop a regional system for producing fuels and other products from perennial grass crops grown on marginally productive land or land that is otherwise unsuitable for annual cropping. This article focuses on contributions CenUSA has made to nine primary systems needed to make this vision a reality: feedstock improvement; feedstock production on marginal land; feedstock logistics; modeling system performance; feedstock conversion into biofuels and other products; marketing; health and safety; education; and outreach. The …

Nebraska Statewide Forest Action Plan - 2015, Scott Josiah, John Erixson
Nebraska Forest Service: Publications
The Nebraska Forest Action Plan identifies strategic goals based on national objectives collaboratively crafted by both the National Association of State Foresters and the USFS State & Private Forestry Program. The strategic goals and actions identified in this document serve as a blueprint for focusing private, state and federal resources in areas of Nebraska where they will be most effective.
Corn Belt Soil Carbon And Macronutrient Budgets With Projected Sustainable Stover Harvest, Zhengxi Tan, Shuguang Liu
Corn Belt Soil Carbon And Macronutrient Budgets With Projected Sustainable Stover Harvest, Zhengxi Tan, Shuguang Liu

Corn (Zea mays L.) stover has been identified as a prime feedstock for biofuel production in the U.S. Corn Belt because of its perceived abundance and availability, but long-term stover harvest effects on regional nutrient budgets have not been evaluated. We defined the minimum stover requirement (MSR) to maintain current soil organic carbon levels and then estimated current and future soil carbon (C), nitrogen (N), phosphorus (P), and potassium (K) budgets for various stover harvest scenarios. Analyses for 2006 through 2010 across the entire Corn Belt indicated that currently, 28 Tg or 1.6 Mgha-1 of stover could be sustainably …
