Through fermentation and enzymatic hydrolysis of various plant-based raw materials from the food industry, high-quality NPK fertilizer solutions are created with directly plant-available organic nitrogen, very little phosphorus, and high potassium for the fruiting phase.

Many crops, both in greenhouses and outdoors, have a high nitrogen requirement in spring. This is due to strong vegetative growth combined with low nitrogen availability from the soil, as the soil is still cool and microbial activity remains limited. If too much potassium is applied during this phase, it can inhibit the uptake of calcium and magnesium, which in turn promotes insect damage.

As soon as the crop transitions into fruiting, the nitrogen requirement decreases. At the same time, nitrogen availability from the soil improves due to higher temperatures, a more developed root system, and increased release of root exudates. However, during this phase, the potassium requirement significantly increases, as potassium is central to fruit set, fruit quality, and transport processes. To keep plants healthy, nitrogen input should not be too high at this point.

For this reason, switching to Organic NPK 2-1-10 is advisable during the fruiting phase.

→ Phosphorus is generally sufficiently available in active soil with good mycorrhization.
