Extension specialists from Plant Pathology, Entomology, Horticultural Science, Crop Science and Soil Science diagnose problems on the samples received.

NCDA Nematode Assay

Plant parasitic nematodes are microscopic threadworms that can feed on plant roots. The NCDA Agronomic Division can assay soil samples for the presence of at least 46 different plant-parasitic nematodes.

NCDA Soil Testing

Soil testing can provide detailed chemical soil analyses, site-specific fertilizer, and lime recommendations, while providing other important management information based on soil location and crop history.
