*Pre-sowing seed treatment together with any protectants. Substance dosage is indicated for the volume of the working solution of 10–20 l.
**Substance dosage is indicated for the working volume of 150–350 l/ha. In case of a significant increase in the consumption of the working solution, the substance dosage should be increased.
We recommend adding the humic substances Ecobiosphere Organic Plus and EcoOrganics Potassium Humate G-Grade to the tank mixture last.
IMPORTANT!
Do not mix humic substances in the same tank with any substances and fertilisers containing calcium and/or saltpetre!
