NIRS as a fast screening technique for total nutrients in strawberry leaves and in spent growing media Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
The first aim is to test the potential of NIRS to forecast the nutrient concentrations in strawberry leaves, which would then allow for assessing the total nutrient uptake by strawberries. A database with 272 strawberry leaf samples with known concentrations of N, P, K, Ca, Mg, Fe, Mn and Na on dry matter (DM) was scanned with near-infrared reflectance spectroscopy (NIRS). These samples originated from different trials in variable conditions, ...
