Organic fertilization for greenhouse crops
Greenhouse crops are the most intensive in the horticultural sector. Organic fertilization in greenhouses must adapt to the controlled conditions of protected crops: high planting density, continuous fertigation and the need for 100% soluble solutions without risk of dripper clogging. Ecoganic products, chloride-free and 100% cold-soluble, are ideal for these systems.

FAQs about greenhouse fertilization
Are Ecoganic products compatible with drip fertigation systems?
+
Yes. All Ecoganic products are 100% soluble in cold water and free of impurities that could clog drippers or filters. Liquid formats (NITROTECH 2.5, CALCIUM 40, K-FLOW 20) are injected directly into the fertigation tank. Soluble solid formats are pre-dissolved in water before being incorporated into the system.
What is the difference between fertilizing in a greenhouse vs outdoors?
+
In greenhouses, crops depend entirely on fertigation for their nutrition since the soil has reduced buffering capacity. This requires products of high solubility and purity, free of chlorides or sodium that could salinize the soil. Ecoganic products, chloride-free and with controlled electrical conductivity, are specially formulated for these systems.
Can calcium and nitrogen be used in the same application?
+
With most conventional mineral fertilizers it is not possible to mix calcium and nitrogen (they form precipitates). Ecoganic products, being of organic origin, do not present this problem: CALCIUM 40 and NITROTECH are compatible in tank mix, which simplifies the fertigation program.
