The cotton industry in Louisiana has seen major structural changes in a short time. Total cotton production was reduced by almost 75 percent between 2005 and 2008. This article explores the future of the cotton industry.

(Distributed03/27/03) Rice planting has begun in South Louisiana, but many farmers in the central and northern parts of the state are looking for options because they’ve been delayed by persistent rains and wet field conditions. That’s where the state’s aerial applicators – pilots with specially equipped aircraft – come in. And many of those aerial applicators take advantage of LSU AgCenter services that help them check their equipment.

Recent rains have drenched Louisiana, and the outlook is not good for the state’s rice crop. Corn and wheat also have taken a beating – but specialists believe the Louisiana cotton crop may have weathered the storm. Double-digit rainfall was recorded in many areas of the state over the past couple of weeks, and totals exceeding 20 inches were seen in some places. Observers even reported as much as 24-27 inches in spots.

Producers heard a variety of experts at the Louisiana Cotton Forum in Monroe.

Louisiana farmers will plant more acreage in rice, soybeans and cotton but less in corn.

Cotton farmers who have access to the Internet can find a lot of information they need on planting and managing their crops, according to an LSU AgCenter expert.

Stressing that production agriculture alone is not enough to sustain rural economies, a leading food science expert said farm productivity needs to be converted to consumer-ready products.

(Distributed 06/20/01) According to figures released by the Louisiana Boll Weevil Eradication Commission, the parishes with the state's highest cotton acreage figures are Tensas Parish with 115,000 acres and Morehouse with 104,000 acres. Dr. John Barnett, cotton specialist with the LSU AgCenter, said cotton farmers across the state are reporting about 896,000 acres.

After Hurricane Katrina made landfall in Louisiana on August 29, 2005, the AgCenter quickly began to assess the damage caused to the agriculture, forestry, and fisheries industries. Since those initial estimates, the AgCenter has refined its projections and now pegs the total economic impact due to losses in revenue and additional production costs at slightly over $1.0 billion.

Based on the information known at the time of the storm, and given the historical value of these industries to the state, the AgCenter was able to provide preliminary estimates on losses of revenue due to production losses.

The LSU AgCenter soon will begin comprehensive tests for salt contamination in areas of Vermilion Parish hit by Hurricane Rita’s storm surge, but officials this week said the problem may not be as bad as originally feared.

Research to date has demonstrated the technical applicability of HT processing for a wide range of plant biomass types, including invasive plant species and preservative-treated wood waste, both of which have little or no economic value and represent an environmental and ecological problem.
