Description
EXAMPLE: KSU Soil Sample Information SheetAcid-based extractions are typically performed on soil samples from fields used for agronomic production; most university soils testing labs affiliated with Agronomy departments used acid-extraction techniques. Linked at right is an example of a submittal form Maria would need to fill out to include with the media sample. She sends in a sample from several pots that contain plants showing symptomology and a sample from several pots that contain plants that appear healthy to the Kansas State University Soil Testing Lab.
