Plant Sap Analyzer
Plant Sap Analyzer
A sap test is a blood test for your crop. Upload a NovaCropControl report and the ranges come straight out of the PDF, or enter values from any lab by hand and set your own.

Why Plant Sap Analysis
Sap analysis shows what nutrients are actually moving through the plant right now, not just what is sitting in the soil.
Catch deficiencies two to four weeks before visible symptoms appear, which is time enough to correct them before yield is affected.
Comparing young and old leaves reveals whether the plant is pulling from reserves or getting fresh uptake. That distinction drives the whole interpretation.
Upload Sap Analysis
Optimal ranges come out of the PDF itself, so the analyzer works with any crop and no range selection is needed. The file is read in your browser and never uploaded.

Fill in only the parameters your lab reported and leave the rest blank. Each parameter needs a value plus an optimal minimum and maximum before it will be included. Units are shown as a guide, but any lab's units work.

About This Tool
Sap analysis measures the nutrients actually circulating in the crop's vascular system. Unlike a soil test, it shows what the plant is taking up and using right now, which is why it reads more like a blood test than a soil report.
Mobile nutrients (N, P, K, Mg, Mo, Cl) can be moved out of older leaves and into new growth when the plant is under pressure. If young leaves run noticeably higher than old leaves and overall levels are borderline, the plant is pulling from reserves, which means current uptake is not keeping up with demand.
Immobile nutrients (Ca, S, Fe, Mn, Zn, B, Cu) largely stay where they were first deposited. If young leaves are short compared to old leaves, or fall below the target range, the roots are not delivering enough. Foliar feeding is usually the fastest correction.
Upload a NovaCropControl PDF and the analyzer reads the crop-specific optimal ranges out of the report itself, or use manual entry to type values from any lab and set your own ranges. Manual entry is what makes the tool work with any laboratory format and any crop.
The optimal band is whatever the report or your entry specifies. The critical, low, high, and excess bands are derived from it, using half the width of the optimal band on each side. For parameters that start at zero, such as nitrate, ammonium, aluminium, and cobalt, there is no low band below optimal. The bands are a reading aid, not a lab standard.
Your report is read entirely in your browser and nothing is sent to any server. This tool is not affiliated with NovaCropControl or any laboratory. Always talk to a qualified agronomist before making a management decision on the strength of these results.
