By definition, trace elements are a class of nutrients made up of pure mineral elements necessary for the life of an organism, but in very small quantities. They are toxic to the body when present at too high a level. The effect of a trace element depends on the dose. When the trace element is said to be essential, a deficiency or on the contrary an excessive intake can lead to serious disorders.

Although these elements are necessary for the plant in minute quantities, they are indispensable: without these elements, the plant will sooner or later have growth problems.

Indeed, NPK is important but not only. The trace elements are also important, such as iron, manganese (Mn), zinc (Zn), boron (B), copper (Cu), molybdenum (Mo), chlorine (Cl), cobalt (Co), and nickel (Ni). Equally indispensable are for example magnesia (necessary for the formation of chlorophyll), zinc (growth factor), copper (which favors the assimilation of potash and nitrogen), boron (which contributes to the formation of cellulose)...

In soil, these trace elements are, in principle, present. Unless the soil is depleted, for example by overexploitation or in a large pot where you just the surface of the soil has been changed and not the entire land.

If the trace elements are missing, the plants have their leaves turn yellow (chlorosis), or dark spots appear on the dry leaves (necrosis of plant tissue). You can find our guide on plant deficiencies to better understand what can happen to your plants.
Too manytrace elements in the nutrient solution is also toxic for plants. Production will be affected. Thus, an excess of manganese can be expressed on the plant as an iron or calcium deficiency! Whether in hydroponics or in soil culture.

Culture Indoor offers many fertilizers that allow you to deliver the right dose of trace elements to the plants in order to always give the plant what it needs. Numerous brands deliver these specific nutrients Canna, Platinium, Biobizz, Plagron aptus...
