ON THE COVER
This aerial photo was taken at about 20,000 feet in 1998 by a company called 3001 Inc. It was made available from the photo service company, GlobeXplorer. Water specialist Bill Branch says it’s about a 10-square-mile area. The highway that runs across the bottom is Interstate 10. Highway 35 runs north and south. The city of Rayne is south of the interstate at its junction with 35. The meandering green line that crosses Highway 35 is Bayou Wikoff. The LSU AgCenter has a water quality research project there. The tufted area on either side of the bayou is forest land. The curved lines in some of the blocks indicate contoured fields. The straight lines in fields, such as in the lower right-hand corner, are precision-graded to a uniform slope to improve water use efficiency. Most areas of the United States, as well as Louisiana, have north-south and east-west property lines. This particular spot is dominated by diagonal lines – probably because farmers traditionally drew boundaries at right angles with Bayou Wikoff.

Old livestock barn
Technology center to emerge from barn site
Groundbreaking for the Louisiana Emerging Technologies Center will be sometime in June, with completion expected the following spring, said Paula Jacobi, CEO of the LSU System Research and Technology Foundation, which will oversee the center.
Rice farmers get more weapons to fight pests
Rice farmers soon will have two more weapons in their arsenals for fighting stink bugs and rice water weevils.
LSU AgCenter establishes natural resource policy center
The Board of Regents and the LSU Board of Supervisors recently approved the establishment of the Center for Natural Resource Economics and Policy at the LSU AgCenter.

Constructing a Wetland To Improve Water Quality
Louisiana’s coastal waters, lakes, rivers and bayous are the lifeblood of the state. They have provided economic survival and year-round recreation, earning the state the well-deserved title of “Sportsman’s Paradise.”

Master Farmer Program: Learning Best Management Practices
Richard Latiolais gazed over the emerald field of an emerging wheat crop near Palmetto in St. Landry Parish.“This is all fresh ground,” he said. “We precision-leveled it last summer.” He is a participant in the LSU AgCenter's Master Farmer Program directed by Carrie Mendoza.
First sweet potato patents awarded
Two sweet potato varieties developed by the LSU AgCenter recently were awarded U.S. patents – the first ones given to sweet potatoes.
Meeting Water Standards for Rice and Soybeans
Because the land is so flat, water flow in Bayou Plaquemine Brule and its tributaries, including Cole Gully, is sluggish and reaeration potential is low. Consequently, inputs of oxygen-depleting materials, such as dissolved or suspended organic material or ammonical nitrogen, are expected to aggravate this naturally oxygen-poor condition.

Water quality research focuses on best management practices
LSU AgCenter research teams are evaluating water quality in the Cole Gully area on the Bayou Plaquemine-Brule in Acadia Parish and in Bayou Wikoff north of Lafayette. Each study area comprises a watershed identified and selected by the Louisiana Department of Environmental Quality.

Overview: Health of Louisiana’s Waters
Louisiana is known as a sportsman’s paradise and the bayou state. When people think Louisiana, they think cypress trees, alligators, seafood, fishing, hunting and trapping. The common thread that runs through all of these images is water.

Water Quality and Soybeans in the Mermentau River Basin
LSU AgCenter scientists have joined with scientists from the LSU Wetland Biogeochemistry Institute and the Louisiana Department of Environmental Quality (LDEQ) to conduct a research project to determine and demonstrate which soybean tillage practices are most effective in reducing pollution. Reducing the amount of runoff from soybean fields means less sediment, fertilizer and pesticide entering local waterways.

Saving Water in Louisiana Rice Production
When drought hit Louisiana in 2000 and 2001, along with the construction of a power plant in the heart of the rice-growing area, interest in water consumption reached a peak among farmers and other water consumers. To find out how much water was used and needed for rice production, a team of LSU AgCenter scientists and extension agents began a study.
Crawfish Harvest
Improving Water Quality in Crawfish Aquaculture
Aquaculture operations worldwide have come under scrutiny because of potential environmental degradation caused by the discharge of water from production facilities. The U.S. Environmental Protection Agency (EPA) is reviewing aquaculture as an industry for regulatory activity. Most of Louisiana’s 129,000 acres of crawfish ponds are located in southwestern and south central Louisiana in water basins identified by the Louisiana Department of Environmental Quality (LDEQ) as impaired.
Cane Residue
Reducing Pollution from Sugarcane and Pasture Fields in Bayou Wikoff
A major objective of the Clean Water Act and the Coastal Zone Management Act is to evaluate, demonstrate and implement best management practices (BMPs) to improve water quality. Because applied agricultural chemicals and sediment are potential contributors to nonpoint-source pollution, it is essential to quantify each commodity’s contribution to water quality problems and evaluate BMPs that can improve water quality.

Salt Water and Irrigation in Louisiana
The salinity of ground water and surface water used for irrigation will always be a concern for Louisiana farmers. Analyses of long-term data on Red River water quality collected by the U.S. Geological Survey (USGS) and of water samples collected by farmers and county agents and analyzed by the LSU AgCenter indicate the Red River can safely be used as a source of irrigation water.

Municipal Wastewater and Pecan Shells
Increased water demand in the face of an essentially fixed fresh water supply and increased pollution of existing supplies by inadequately treated waste discharge have been identified as problems in Louisiana. The purpose of this study was to determine the effectiveness of treating contaminated water such as municipal wastewater with a by-product of tree nut production in Louisiana, namely, pecan shells.

Water: Vital Link to Louisiana’s Economic Future
From the rich coastal waters along the Gulf of Mexico to the freshwater rivers, streams and lakes north of the coastal zone, water resources are an integral part of life in Louisiana. Historically, the challenges pertaining to water have been linked to flooding of developed areas caused by excessive rainfall or increased flow from the Mississippi River.
Master Farmer Program makes sense, saves cents
In January 2001, the LSU AgCenter offered the first Louisiana Master Farmer training session in Vermilion Parish. More than 60 producers attended to become more knowledgeable about Louisiana environmental regulations, specifically water quality and nonpoint-source standards.
