Biostimulants for Coffee: Maximize Quality and Yield

## Organic Coffee Worldwide: Opportunities and ChallengesOrganic coffee is gaining ground in the global market with an annual growth of over 8%. This trend is driven by increased awareness of sustainability and health, as well as consumer preference for more natural and pesticide-free products. Organic coffee prices are typically 20-40% higher than conventional coffee, representing a significant opportunity for coffee growers who can access this market.Colombia, Brazil, Ethiopia, and Vietnam are some of the world’s leading coffee producers. Colombia produces approximately 13 million bags of coffee annually, while Brazil leads with a production of 60 million bags. Ethiopia and Vietnam are also key players, with Vietnam being the main producer of Robusta coffee. The demand for certifications such as Fair Trade, Rainforest Alliance, and organic is increasingly strong, as consumers seek to ensure their purchases contribute to sustainability and fair trade.## Agronomic Requirements of CoffeeCoffee cultivation requires specific conditions depending on the species. Coffea arabica, known for its smoother taste and bright acidity, thrives at altitudes between 900 and 2000 meters above sea level, with ideal temperatures of 18-22°C and annual rainfall of 1500-2500 mm. Arabica varieties like Colombia, Castillo, Caturra, Bourbon, Geisha, and SL28 are popular for their cup quality and adaptability to different climates and altitudes.On the other hand, Coffea canephora (Robusta) is grown at lower altitudes, between 0 and 900 meters above sea level. This species is disease-resistant and has a higher yield, although its flavour profile is less appreciated than Arabica.The phenology of coffee comprises several critical phases: budding, flowering, fruit setting, grain development, and maturation, which can last between 8 and 9 months. Each of these stages requires specific agronomic management to ensure optimal yield.## Main Issues in Organic Coffee and the Role of BiostimulantsOrganic coffee cultivation faces several challenges, with coffee leaf rust (Hemileia vastatrix) being one of the most significant, with estimated losses of 30-40% of production. The coffee borer (Hypothenemus hampei) and coffee berry disease (Cercospora coffeicola) are other pests that significantly affect crops. Additionally, water stress during flowering and nutrient deficiencies such as potassium (K), magnesium (Mg), and boron (B) can affect plant health and productivity.Biostimulants play a crucial role in organic agriculture by enhancing the natural defenses of plants, improving nutrient uptake, and increasing stress resistance. Products like Boost Universal and Balance 7-7-7 from Ecoganic can help coffee growers tackle these challenges efficiently and sustainably.## Ecoganic Biostimulant Program for Coffee Phase by Phase

## Impact on Cup Quality: From Farm to CupCoffee quality is measured not only in terms of quantity but also in grain quality and sensory profile. A Brix content in ripe cherries above 22°Bx indicates a good level of sugars, which is essential for high-quality coffee. The grain moisture should be maintained between 11-12% to avoid storage issues and preserve organoleptic characteristics.The fermentation process and pulp-to-grain ratio are crucial for developing the desired flavours in the cup. Professional cuppers look for bright acidity, creamy body, and floral aromas in high-quality coffee. Biostimulant programs can increase the coffee’s score in Q Grader evaluations by 2-4 points, which is significant for the specialty market.## Quantifiable Field ResultsTrials conducted in Colombia and Guatemala have shown an increase in coffee production of 20-35% in kg/ha when using Ecoganic biostimulants. Additionally, a significant reduction in the incidence of rust has been observed, improving the overall health of the coffee plantation. Cup quality has also shown improvements, with an increase of up to 3 points in cupping.## Organic Coffee in LATAM and Africa: Zones and CertificationsIn Latin America, Colombia and Brazil are leaders in organic coffee production. Colombia holds certifications such as USDA NOP and Fair Trade, while Brazil is recognized for IBD organic. In Central America, Guatemala stands out with Anacafé certification. In Africa, Ethiopia is a major producer and is certified by EOCERT. Exporting to the European Union requires compliance with Regulation (EU) 2018/848, which sets strict criteria for organic production.## Compatibility with Organic Certification and Fair TradeEcoganic products are approved under Regulation (EU) 848/2018, USDA NOP, and Demeter, ensuring they contain no synthetic components and are suitable for organic agriculture. The batch certification process ensures that products meet the necessary standards to be considered organic and fair trade.## Coffee Varieties: A Guide for the Organic Coffee Grower
