Nutrient Dynamic and Extraction of Plant Sap 

Due to water and nutrient flow through the plant, stems and trunks exhibit diameter variations that are directly related to sap flow. 

Ions (cations and anions) in soil and plants are essential nutrients for plant development and growth. An imbalance of ions can lead to symptoms, diseases, or, ultimately, plant death.  

We have developed a plant SAP extraction method, a cutting-edge technology that effectively addresses nutrient deficiencies and facilitates accurate adjustments in crop nutrient amendments to correct imbalances. Plant sap analysis allows us to determine and apply the precise amount of needed nutrients before deficiencies manifest as diseases or weaknesses. Through sap analysis, we can learn about the plants’ ion composition during cultivation, identify the nutrient elements they require, and thus provide precise and suitable ion supplements. 

Knowing that, Plant SAP helps to:

• Detect all active nutrients in the xylem and phloem.

• Compare the nutrients present in both the new and old plant growth.

• Allows for fixing imbalances in plant nutrition and detecting current and future deficiencies (nutrient deficiency-sufficiency)

SAP sampling differs significantly from tissue sampling: while tissue sampling collects only newly matured leaves, providing a snapshot of the plant’s condition at a specific moment, SAP sampling offers a broader perspective. By sampling both new and older growth, SAP sampling enables the tracking of nutrient availability over time. This helps identify when a deficiency begins in the new growth and how the plant compensates by drawing nutrients from older tissues. As a result, SAP sampling presents a more comprehensive picture of the plant’s nutritional status, both current and predictive.
