Stakeholders helping to protect Cedar Creek Watershed

Water quality has declined in the Cedar Creek Reservoir, but experts with The Texas A&M University System are helping landowners and government officials develop plans to clean the water that flows into the 160-acre lake.

Stakeholders in the reservoir’s four-county watershed have an opportunity to offer opinions and help draft the Watershed Protection Plan for Cedar Creek Reservoir.

Experts with Texas Cooperative Extension, the Texas Agricultural Experiment Station and the Tarrant Regional Water District have led efforts to form the committee. They will collaborate with the Texas Water Resources Institute on efforts to study water quality and improve the reservoir.

Public feedback sought on Pecos River Watershed Protection Plan

Project members of the Pecos River Basin Assessment Program with stakeholder inputs recently completed a draft of the Pecos River Basin Watershed Protection Plan and are seeking further input from the public about the plan.

Project collaborators include landowners and stakeholders, Texas Cooperative Extension, Texas State Soil and Water Conservation Board and Districts, Texas Agricultural Experiment Station, Texas Water Resources Institute, the U.S. International Boundary and Water Commission, and Texas Clean Rivers Program. Funding is provided by the Texas State Soil and Water Conservation Board through a Clean Water Act grant from the U.S. Environmental Protection Agency.

Draft copies of the protection plan and on-line comment instructions are available at http://pecosbasin.tamu.edu.

Grant funds assembly, testing of on-farm manure-to-energy conversion system

The Texas Water Resources Institute and Texas Cooperative Extension recently received a grant from the USDA Natural Resources Conservation Service to test an on-farm manure-to-energy conversion system for future use on Central Texas dairies.

The grant is funding the assembly and testing of a portable energy generation unit that is otherwise known as a thermophilic digester and fluidized bed gasifier system.

Dr. Saqib Mukhtar, Extension agricultural engineer and one of the project leaders, said, “We're trying to find ways to divert excess manure and reduce repeated and excessive application of phosphorus to waste application fields that can potentially become a non-point source of pollution.”

The portable unit will have an anaerobic digester to produce methane and carbon dioxide, which will be used as a source of energy. The second part of the system is a gasifier, used to gasify fossil fuel or biomass including manure.

Other researchers with the Texas Agricultural Experiment Station involved are Dr. Cady Engler, professor, and Dr. Sergio Capareda, assistant professor, of the Department of Biological and Agricultural Engineering.

TWRI hires staff, gains project for Arroyo Colorado watershed

Texas Water Resources Institute recently added three staff members and one project to work with the Arroyo Colorado Watershed Partnership (ACWP) on water quality improvements in this South Texas watershed.

The ACWP was originally organized by Texas Coastal Watershed Program, which is part of Texas Sea Grant and Texas Cooperative Extension, in cooperation with the Texas Commission on Environmental Quality (TCEQ) and the Texas State Soil and Water Conservation Board (TSSWCB).

Take the Earth Kind challenge

Earth Kind, a Texas Cooperative Extension program promoting environmental stewardship for urban landscapes, is offering an online challenge to help with environmentally friendly landscaping. This 25-question quiz asks for input about topics such as landscape design, plant selection, efficient irrigation and insect and disease management and then generates a personalized score to let the person taking the challenge know how well his or her garden is sustaining a healthy environment.

Dr. Don Wilkerson, professor in Texas A&M University’s Department of Horticulture and one of the developers of the challenge, said if the person is using anything other than the optimal Earth Kind practices, the challenge will then suggest changes in landscape practices that would help create a healthier and more sustainable environment. It will also provide additional information, including links to Earth Kind publications.

Wilkerson encouraged users to complete the online evaluation of the challenge, as it will help Extension evaluate the success and impact of the program.

The principle goals of Earth Kind include water conservation, safe use and handling of fertilizers and pesticides and reduction of yard waste entering landfills.

TTI's Erosion Control Lab helps protect Texans' water supply

With the record rainfall, Texas has experienced an increase in water pollution from erosion. The Texas Transportation Institute’s (TTI) Hydraulics, Sedimentation and Erosion Control Laboratory (HSECL)tests erosion-control products used by the Texas Department of Transportation to help prevent erosion and sediment run-off.

"Heavy and frequent rainfall during road construction projects can lead to some of the worst environmental problems unless the proper erosion and sediment control measures are in place to minimize the amount of sediment leaving the construction site," said Assistant Research Scientist Jett McFalls. Many of the products seen along construction sites to control erosion have been tested at TTI's HSECL.

Texas A&M Engineering researchers receive grants for Ag-based energy

Texas A&M Engineering researchers have received Sun Grant Initiative grants for research into developing and enhancing new sources of energy based on agricultural products.

The Sun Grant Initiative will make available approximately $2.5 million during the next three years to area scientists and engineers. The initiative is a national program established to create new solutions for America’s energy needs and to revitalize rural communities by working with land-grant universities and their federal and state laboratory partners on research, education and extension programs.

New Projects

Assembly and Testing of an On-Farm Manure to Energy Conversion BMP for Animal Waste Pollution Control

Project personnel will assemble and test a thermophilic digester and fluidized bed gasifier system, also known as an On-Farm Manure to Energy Conversion System (OFMEC), that can be used as a demonstration tool to show dairy producers how they can convert the waste stream of their dairies into energy that can power their farms and/or homes.

Principal Collaborators: Texas Water Resources Institute, Texas Cooperative Extension, Texas A&M University Biological and Agricultural Engineering Department

Funding Agency: USDA Natural Resources Conservation Service

Bacteria Runoff BMPs for Intensive Beef Cattle Operations

This project will demonstrate and evaluate the effect of grazing management on pathogen transport from an intensively managed irrigated pasture at the Texas A&M University Farm in Brazos County. Management guidelines will be developed based on the evaluations. These guidelines and other materials developed through this project will be transferred to USDA Natural Resources Conservation Service, Texas State Soil and Water Conservation Board, local soil and water conservation districts, Texas Cooperative Extension and livestock producers for incorporation into educational, technical assistance and cost-share programs and implemented by producers.
