Description

Top Substra is a partly coated fine-grained NPK fertilizer designed for subtrate mixtures. It combines an immediate with a long-term nutrient supply.
The nutrients are released in two steps:
1) Starter effect after application under moisture influence. As a result, the relatively high immediate demand is met.
2) In a second step, the coated granules release the nutrients via diffusion influenced by moisture and temperature.
Mixing into substrate is recommended directly before use (maximum storage time 10 days).

Benefits

• Immediate and long-term effect combined
• 30 % of coated granules for a long-term feeding up to 3 months
• Fine and homogenous granules for a good distribution in the subtrate mixtures
