A crop's growth and development can be severaly impacted by a deficiency in one or more elements. The uptake of plant nutrients depends on many different factors such as pH and EC. The climate – albeit a factor that is out of our control – is also an important variable.
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:
Variables such as temperature, light, and relative humidity ascertain the rate of evaporation, therefore impacting nutrient absorption and movement within the plant. The interaction between different nutrients also comes into play; an excess of one element can hinder the uptake of another.
In an oven-dried plant material, the dry matter analysis determines both the bound and dissolved nutrients therefore providing information on all the nutrients present in the plant. Eurofins Agro has an extensive database of target values for a wide range of crops, allowing you to compare your results with what we would recommend for your specific crop.
