Sap Analisis
Stop guessing. Measure what the plant is actually telling you.
Plant stress is primarily driven by nutritional imbalances — the main trigger behind pests and diseases. By measuring Brix (°Bx) and sap pH, we assess photosynthetic efficiency and metabolic balance directly in the field. This approach is grounded in the concept of trophobiosis, developed by Francis Chaboussou: when plant metabolism is unbalanced, it becomes an invitation to pests and diseases.
Instead of relying solely on conventional soil analysis — which reflects only the chemical condition of the soil at a specific moment — we evaluate the plant itself. The presence of nutrients in the soil does not guarantee uptake, making plant-based measurement the most reliable way to understand crop nutrition.
Through rapid sap testing, we detect early stress and identify what the plant is lacking. We measure Brix before and after applying specific foliar nutrients directly to the leaves, allowing us to immediately see which one improves plant performance. This shows exactly which nutrient is limiting photosynthesis, so corrections can be made quickly and with precision — avoiding guesswork and unnecessary inputs.
The result is a crop brought back into physiological balance — moving it out of a stress condition where pests and diseases can develop. This leads to improved productivity and a significant reduction in the need for chemical inputs.
These tools integrate seamlessly with multispectral drone mapping, allowing us to identify and visualize areas of physiological stress across the field. This enables targeted field evaluation, focusing sap analysis precisely where it is needed to support accurate and efficient decision-making..
