Tissue analysis is conducted at various growth stages to determine elemental content of a particular plant part for one or more macro or micro nutrients. Sampling and sample preparation are an important part of the overall process.
Decontamination to remove foreign substances may be necessary, particularly if the tissue is covered with dust or spray materials that contain elements included in the analysis.
Oven drying (55-65 C) and sample size reduction (grinding) prepares the sample for laboratory analysis.
The KSU Soil Testing Lab only offers one test package for agricultural lime analysis, which includes fineness factor, calcium carbonate (CaCO3) equivalent, effective calcium carbonate, weight on 8-mesh sieve, weight on 60-mesh sieve, and weight through 60-mesh sieve.
When the analyses are complete, a report will be mailed including data for the above parameters and will be signed by the analyst completing the report.
When collecting samples for lime analysis, remove the top 12 inches of the each sample area to remove eroded material before collecting the sample. Approximately 10 profile samples should be taken to a depth of 5 feet (if possible). The samples can be combined and submitted to the KSU Soil Testing Lab in a water-tight container.
