A deficiency in one or more elements can often have serious consequences for the growth and development of the crop. The uptake of plant nutrients depends on many different factors. pH and EC are not the only important variables – the 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.
Crop Check
In oven-dried plant material, the dry matter analysis determines both the bound and dissolved nutrients. It therefore provides you with 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.
