Yield and quality of harvest products are affected by various factors: Apart from site conditions, type of cultivation, crop rotational systems, plant protection measures and not least fertilization play a decisive role.

Regarding fertilization strategy, focus must not only be put on macronutrients (NPK). Sufficient supply with trace elements must also be ensured. For a lack of micronutrients such as copper cannot be compensated by an oversupply of other nutrients according to the Law of the Minimum (Justus von Liebig).

With Plonuran® WP and Plonuran® liquid, trace nutrients fertilizers that counteract copper deficiency are available. The fertilizers can be used according to the current need of the plants that can be determined via soil or plant analysis. Stock fertilization is also possible with Plonuran®
