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 PRICE LIST.

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.

Feed Program

All feed and pet food sold in Louisiana must be registered annually July 1 through June 30.

Annual Registration of Commercial Feeds & Pet Foods 2016/17

Fill in the feed and pet food registration form and enclose a check payable to the Louisiana Department of Agriculture & Forestry to cover payment of the annual registration fee of $40 plus the label fee (depending on the number of products you are registering – $10 each up to 50, $8 each for 51-200, and $6 each for 201 and over) for all products being registered.

You must submit all product labels (new or revised) being registered in the State of Louisiana. An additional fee of $50 will be charged for renewal companies registration POSTMARKED after June 30. For companies selling commercial feeds in packages of ten (10) pounds or less, a $200 annual specialty fee is required in lieu of the inspection fee (tonnage fees). This is to be submitted with your annual registration application.

All companies registered as a feed manufacturer must submit quarterly tonnage reports.


Feed Commission Minutes and Proceedings are available HERE

Inspection fees are computed at one dollar per ton for each ton sold. There is a minimum quarterly inspection/tonnage fee of $10.The penalty, a 25 % late fee, for late reports will be in addition to the minimum $10.00 fee (total of $12.50). If you pay the annual $200 specialty fee, there is no fee due with your report(s). However, the report(s) must be filed quarterly (FAX NUMBER 225-342-0027).

Companies that fail to timely submit tonnage reports may be subject to a civil penalty.

If you have any questions, please call Cheryl McGee at 225-342-5812 or send an e-mail.


Fertilizer Program


In accordance with Louisiana Fertilizer Law R.S. 3:1411 et seq., and the Rules and Regulations of the Louisiana Feed, Fertilizer and Agricultural Liming Commission, LAC 7; Part X1 Sections 101 through 137, all companies that manufacture or ship fertilizer into the state of Louisiana must both register as a fertilizer manufacturer and file quarterly tonnage reports with the Louisiana Feed, Fertilizer and Agricultural Liming Commission.

All shipments must be invoiced as a grade by each manufacturer or mixer, whether mixed by said mixer or purchased from another manufacturer or mixer. Each manufacturer or mixer must pay an inspection fee on ALL sales.

All shipments must have proper guaranteed analysis identification on bags and a copy of the shipping ticket or an invoice when the shipment is made in bulk. A copy of the shipping ticket, giving complete information, must accompany delivery vehicle.

Fertilizer-pesticide combinations must be registered under both laws, and the name and percent of pesticide active ingredients must be shown on the delivery ticket.

Analytical Chemistry Laboratory Programs


The Agricultural Analytical Chemistry Laboratory serves as the State Chemist’s laboratory for official analysis of feeds, fertilizers, liming materials, pesticides, meats and other analyses requested by the Louisiana Department of Agriculture and Forestry.

It is also the Louisiana State University Agricultural Center’s primary service laboratory for research samples for water, plant tissue, feeds, fertilizers, alternative limes, pesticides and other specialized analysis. In addition, the laboratory also serves the public with analysis of manufacturers’ feeds and fertilizers, producers manures and poultry litters, meats, turtle dip antibiotics, farmer aflatoxin and fumonisin samples, and other specialized testing.
