Why does Agromaster 19-5-20+4MgO and Vitalnova rise-P perform better?
- By using Agromaster, controlled release fertilizer, the Nitrogen is released gradually, following the growth stages and contributing to higher quality.
- Decreasing the number of Nitrogen applications from 2 to 1, it eliminates short periods of high nitrogen input. Balanced nutrition and healthier plants are achieved while avoiding soil compaction.
- Vitalnova rise-P promotes Phosphorus availability in the soil and thus increasing the number of tubers per hectare and the marketable yield
