SAP® Analysis

SAP® analysis offers a highly accurate and topical assessment of the true nutritional status of the plant.

Whereas conventional tissue testing reports the level of nutrients in a sample, including those locked up and unavailable for growth in cell walls and storage cells,  SAP analysis measures only the actual level of crop nutrients available for plant growth.

OMEX offers a full nutritional analysis service using the facilities of the Scientific Agricultural Partnership (SAP®) laboratories in King’s Lynn.

The laboratories specialise in the extraction, analysis and interpretation of sap samples taken from growing plants.

Individual interpretation of each sample result is carried out by a team of qualified agronomists, allowing recommendations to be made for the active nutritional management of the crop.

SAP Analysis

 

The Facts

  • SAP is a unique service using purpose built laboratories and sap extraction process.
  • 17 parameters are analysed to give a complete picture of the plant’s nutritional status.
  • The crucial database used to interpret the sap analysis results has been built up over 50 years.
  • On farm trials have shown improvements in marketable yield and quality when the SAP system is used

The SAP System

The full SAP system begins with an initial complete soil analysis, base fertiliser recommendation (applied as a bespoke suspension fertiliser, if appropriate) and up to 5 full spectrum SAP tests at programmed intervals during the growing season

SAP Health Checks

Alternatively, one-off health checks can be provided on a wide range of crops, with a rapid turnaround of results. The recommendations are emailed or faxed within 2-3 days of receipt of the samples, making it an excellent management tool for the grower.

SAP Analysis

  • The SAP analytical report will show the level of No3, NH4, P, K, Mg, S, Ca, Na, Cl, Mn, B, Cu, Fe, Zn, Mo, Al, and pH
  • The report provides an easy to interpret bar chart, with agronomist’s comments.

When and How to Sample

  • SAP sampling procedures are crop specific. Full details and sampling instruction are supplied in the ‘SAP Pack’.
  • Sample when problems are seen, when the crop is under stress, or prior to a growth surge.
  • Sample in a representative manner, either in a pre-marked ‘W’ or in a straight line.
  • Sample early in the morning before the dew has lifted.
  • Select the oldest actively growing leaf and petiole from at least 20 plants.

SAPMIX

If necessary, a tailor-made product can be manufactured based on the results to suit specific crop or growing conditions and to help plants achieve maximum yield and quality potential.

Full details of the sampling technique are contained within the SAP Packs.
