A deficiency in one or more elements can often have serious consequences for the growth and development of the crop. Plant nutrient uptake depends on many different factors. Besides pH and EC, climate is also an important factor.
Temperature, light and relative humidity determine the rate of evaporation and therefore the uptake and transport of nutrients. The mutual relationship between the various nutrients present also plays a role, as too much of one element can inhibit the uptake of another. There are two methods of obtaining an insight into the nutrient uptake and nutrient levels of the crop during the season:
Crop Check
In oven-dried plant material, the dry matter analysis determines both the bound and dissolved nutrients. It therefore gives you information on all the nutrients present in the plant. The results are presented in g/kg, μg/kg, %/kg or mmol/kg dry matter. Eurofins Agro has an extensive database of target values for a wide range of crops, allowing you to check whether the values presented in the analysis of your plant material match the guideline values for your crop.
Plantsap Check
The plant sap analysis determines the nutrient composition of pressed plant material that has been frozen and thawed.

Eurofins Agro analyses samples according to prescribed and established methods. The analysis report briefly describes the method. Here you can also see which method has been accredited by the Accreditation Council. We then put a Q after the method.
The pdf below (in Dutch) contains a detailed description of the methods. This document supplements the information on the analysis report.
