Research Project: DEVELOPMENT OF AN IN SITU-NON-INTRUSIVE, REAL-TIME FUEL-VALUE ESTIMATOR OF FEEDLOT BIOSOLIDS
2010 Annual Report


1a.Objectives (from AD-416)
To apply sub-surface electromagnetic soil conductivity methods combined with other remote-sensing technologies to identify suitable feedlot bio-solids for direct combustion.


1b.Approach (from AD-416)
Texas Agri-Life Research-Amarillo will provide extensive knowledge of combustion processes and properties related to cattle feedlot bio-solids as a fuel. Furthermore, Texas Agri-Life Research will coordinate with the Texas Cattle Feeders Association to facilitate access to commercial feedlots in the Texas Panhandle for sub-surface surveys, feedlot soil samples, and feedlot management information. Soil samples will be analyzed for combustion properties and chemical constituents by USDA-ARS and Texas AgriLife Research. Models relating soil sample constituents and combustion processes will be refined by Texas AgriLife Research and USDA-ARS scientists. Additional model development for attributes of the feedlot surface, such as depth of bio-solids accumulation, will be developed by Texas AgriLife Research and USDA-ARS scientists.


3.Progress Report

Texas AgriLife Extension and Research Center has provided knowledge of combustion processes and properties related to cattle feedlot biosolids as a fuel. Furthermore, AgriLife Extension has provided access to commercial feedlots in the Texas Panhandle for sub-surface surveys, feedlot soil samples and feedlot management information. Initial soil samples have been analyzed for combustion properties and chemical constituents by USDA-ARS at USMARC. Preliminary models have been developed and are being evaluated.
