Agricultural Chemistry Programs

The Division of Agricultural Chemistry, Louisiana Department of Agriculture and Forestry, administers the feed, fertilizer and agricultural lime regulatory programs for the state of Louisiana. The Agricultural Chemistry Laboratory performs analytical testing on animal feeds, pet foods, plant food and agriculture liming materials for the Louisiana Department of Agriculture and Forestry. Analyses are performed on plant and animal tissues, soil, water, feeds, fertilizers, pesticides agricultural chemicals and agricultural commodities.

The Ag Chemistry Laboratory also provides analytical services to the Pesticide Division of the Office of Agriculture and Environmental Sciences as well as the Meat Program of the Office of Animal Health and Food Safety. The programs administered by the division protect the quality and safety of food, feed, fertilizer and other agricultural inputs. This protection directly benefits all the citizens of the state by protecting the quality and safety of the food supply and the environment.

The Agricultural Chemistry Laboratory, housed on the LSU Campus, is currently a part of the Food Emergency Response Network (FERN). This network is a FDA/USDA funded system of laboratories that maintains readiness to respond to food emergencies.

Our association with FERN has provided numerous training opportunities for our staff at no cost to the state.

The Agricultural Chemistry Division provides analytical chemistry support to the research and extension efforts of the LSU AgCenter. Analyses are performed on plant and animal tissues, soil, water, feeds, fertilizers, pesticides agricultural chemicals and agricultural commodities. The laboratory will analyze these sample types for the general public for a fee. Please call 225-342-5812 for your analytical needs and a FEE SCHEDULE.

AgChemistry has analytical capabilities to perform tests for protein, fat and fiber in feeds, nutrients and metals in water, chemical residue matrices, antibiotic use in feeds, PCBs in marine mammals, melamine in feeds and for other studies. Laboratory equipment available within the AgChemistry unit include state-of-the-art multiple gas and liquid chromatographs, ICP and tandem mass spectrometers.

The regulatory, research and extension work done by Ag Chemistry includes analyses of over 10,000 samples per year. In addition, Louisiana consumers are assured quality product purchases with registration and review of product labels on feeds, pet foods, fertilizer and agricultural liming products.

The laboratory is located on the campus of Louisiana State University in Baton Rouge, La. Click here more information.

If you have not already provided your fertilizer product labels to us, or if you have any new products, please submit them with your application for registration.

Application for Fertilizer Registration

Small Package Goods Exception (Louisiana Fertilizer Law R.S. 3:1413(C)(1))

“Small packages” is defined as less than 5 gallons of liquid fertilizer and less than 50 pounds of dry material.  Fertilizer manufacturers who intend to sell only small packages, not to exceed a total of 100 tons per year, must sign the statement under the ‘small package goods exception’ part of the registration application form or click the corresponding check box in the online system. A $100.00 fee is required at the time of registration for the exception and is in lieu of quarterly inspection fees; however, accurate quarterly tonnage reports must still be submitted to our office.  Any sales over 100 tons will be subject to the $1.00 per ton inspection fee.

Quarterly Tonnage Reports

All registered fertilizer manufacturers must timely submit accurate quarterly tonnage reports even if there were no sales during the quarter.  The inspection fee is $1.00 per ton; the minimum fee is $10.00 per quarter. The inspection fee must be paid to the commission on all fertilizers sold and submitted with the quarterly tonnage reports.  The inspection fee is only required to be paid once on each lot of fertilizer sold.  Checks should be made payable to the Louisiana Department of Agriculture & Forestry (LDAF).

LA R.S. 3:1413(C) provides that tonnage reports and inspection fees shall be due and payable on the first day of October, the first day of January, the first day of April, and the first day of July.
