Organic fertilization for vegetables
Vegetables are high-demand, short-cycle crops that require precise fertilization at each phase. Organoleptic quality — BRIX, color and firmness — depends directly on potassium and calcium nutrition during the bulking phase. A well-designed, highly soluble organic program can increase BRIX by up to 25% and significantly improve post-harvest life.
Recommended products for vegetables
All certified CE 2018/848 + NOP USDA. 100% soluble for fertigation.

NITROTECH 10
High-concentration liquid organic nitrogen to cover high demand during active growth. Ideal for drip fertigation with no clogging risk.
NPK 10-0-0 · 10 L, 20 L, 300 L

CALCIUM 40
Micronized calcium <1μm to prevent blossom-end rot in pepper and tomato, and tipburn in lettuce. Improves firmness and post-harvest life of all vegetable crops.
NPK 0-0-0+Ca · 1 L, 5 L, 10 L

K-FLOW 20
High-purity potassium with 23.21 % measured K₂O to maximize BRIX, coloring and sugars in pepper, cucumber, melon and zucchini. Key for final organoleptic quality.
NPK 0-0-20 · 10 L, 20 L, 1000 L

BOOST UNIVERSAL
Freshwater unicellular algae biostimulant to improve fruit set, reduce flower abortion and increase tolerance to water and thermal stress in vegetable crops.
NPK 0-0-1 · 1 L, 5 L, 10 L

PHOSMAX 20
Assimilable phosphorus to stimulate root development after transplanting. Essential in short-cycle vegetable crops where fast establishment determines final yield.
NPK 0-20-0 · 1 L, 5 L, 10 L

How to increase BRIX in organic vegetables?
+
BRIX (sugar degrees) in vegetables depends mainly on potassium nutrition during the bulking phase. Ecoganic K-FLOW 20, with 23.21 % measured K₂O, provides high-purity potassium that optimizes sugar transport to the fruit. In a trial with zucchini, a 25% increase in BRIX was recorded with NITROTECH applied through fertigation. Combining K-FLOW 20 with CALCIUM 40 also improves firmness and post-harvest life.
How to prevent blossom-end rot in organic pepper and tomato?
+
Blossom-end rot (pepper and tomato) is a physiological disorder caused by calcium deficiency in the developing fruit. Regular applications of CALCIUM 40, with micronized calcium at particle size <1μm, ensure fast and efficient absorption even under high temperature or water stress conditions. Application every 7-10 days during fruit set and bulking is recommended.
Are Ecoganic products suitable for certified organic vegetables?
+
Yes. All products in the Ecoganic range are certified under CE 2018/848 (EU), NOP USDA (USA) and JAS (Japan). They are suitable for certified organic vegetable production under any recognized control body in Spain and Europe, including Caae, Ecocert, Bureau Veritas and others.
