Plant Diagnostic Center
The Plant Diagnostic Center is a service of the LSU AgCenter and is supported by the Department of Plant Pathology and Crop Physiology. Routine plant diagnostic services are provided to extension personnel across Louisiana as well as to state residents at a charge of $20 per sample. The center diagnoses plant samples with problems caused by fungi, bacteria, viruses, nematodes, insect pests and mites, as well as nonpathogenic agents and weed identification.
These labs at the W.A. Callegari Environmental Center offer analytical services to research, public and private clientele. The labs perform more than 50 analytical procedures from simple to the most sophisticated determination of chemicals in water, solid and semi-solid materials.
The Soil Testing and Plant Analysis Laboratory offers a variety of soil, plant tissue and water tests to the general public and research community. With an integrated effort from both research and extension agronomists, the LSU AgCenter Soil Testing and Plant Laboratory is the only laboratory that incorporates latest Louisiana-specific soil fertility research in its recommendation system to help farmers to meet today's challenges in agricultural production.

The Ag Chemistry Lab is part of the Department of Agricultural Chemistry. The lab provides analytical support for research and extension efforts of the LSU AgCenter as well as for the Louisiana Department of Agriculture and Forestry. Analysis 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.
The laboratory is equipped to provide both NIRS (near-infrared reflectance spectroscopy) and conventional wet chemistry testing. Samples can be analyzed for dry matter (DM), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude protein (CP) and minerals (Ca, P, Mg, K, Cu, Zn, Mn). The standard procedure for samples received by the laboratory includes DM (oven dried) and CP, NDF, ADF and TDN (Total Digestible Nutrients) estimated with NIRS. Wet chemistry is performed on samples unsuitable for NIRS analyses. Additional analyses, such as in vitro true digestibility (IVTD) and soluble nitrogen concentration, are also performed for many research projects.
