Abstract (en)

[origin: WO03010535A1] A method of controlling the application of fertilisers, fungicides, herbicides or pesticides to a plant crop, comprising simultaneous real time measurements of chlorophyll and/or biomass contents by determining the Reflectance Vegetation Index (RVI) or an equivalent measure for chlorophyll and/or biomass content and crop leaf area by determining Leaf Area Index (LAI) or an equivalent measure, providing such measurement data to a data processing unit which calculates an RVI/LAI ratio or an equivalent ratio as an indication of the chlorophyll content per unit leaf area, said data processing unit is operably connected with a control unit regulating the application of fertilisers, fungicides, herbicides or pesticides to the plant crop.
