Biostimulants for Avocado: Complete Guide to Ecological Nutrition

## Why Does Avocado Need Organic Biostimulants?Avocado cultivation faces several agronomic challenges that require effective solutions to optimise production sustainably. One of these challenges is alternate bearing, a phenomenon that can cause significant variations in annual tree yield, directly affecting the economic stability of producers. Additionally, avocado is a crop with high water demand, especially during flowering and fruit set phases, making efficient water management crucial to avoid water stress and ensure good fruit development.The avocado market is also experiencing significant growth, particularly in the premium segment, where consumers seek high-quality products produced sustainably. This is where Ecoganic’s organic biostimulants play a crucial role, as they help improve soil and plant health, increase disease resistance, and optimise nutrient and water use without compromising the environment. This not only enhances fruit productivity and quality but also ensures compliance with organic production regulations, such as Regulation (EU) 848/2018 and USDA NOP, allowing farmers to access international markets.## Agronomic Requirements of AvocadoAvocado (Persea americana) thrives in specific climatic conditions critical for its optimal development. The ideal temperature for avocado cultivation ranges between 20°C and 25°C, being particularly sensitive to frost and extreme temperatures that can affect both flowering and fruit quality. Regarding rainfall, avocado requires approximately 1200 mm of rain annually, evenly distributed, although an efficient irrigation system is essential to meet water needs during dry periods.The most suitable soils for avocado cultivation are loamy-clay with a pH ranging from 5.5 to 7.0, offering good drainage and nutrient retention. The most commonly cultivated commercial varieties include ‘Hass’, ‘Fuerte’, ‘Bacon’, ‘Lamb Hass’, and ‘Ready’, each with particular characteristics. For example, ‘Hass’ is the most popular variety due to its high quality and transport resistance, while ‘Bacon’ is valued for its cold resistance. Although partially self-compatible, the use of pollinators can improve production.## Main Agronomic Problems of Avocado and Solutions with Biostimulants### Phytophthora cinnamomi — RootRoot rot caused by Phytophthora cinnamomi is one of the most devastating problems for avocado, reducing nutrient and water absorption, and in severe cases, leading to tree death. Ecoganic biostimulants, such as Universal Power OCC, help strengthen the root system by promoting beneficial soil microorganisms, improving resistance to pathogens.### Verticillium dahliaeThis soil fungus causes avocado wilting, affecting water and nutrient flow. Applications of Micro Plus can significantly reduce incidence by improving soil health and promoting a balanced microbiota that competes with pathogens.### Alternate BearingAlternate bearing is a phenomenon where trees produce abundantly one year and little the next. Boost Universal applied during flowering and fruit set phases can help stabilise annual production by improving the plant’s hormonal balance.### Water Stress During Fruit SetWater stress is critical during fruit set, affecting fruit retention. The use of Nitrotech 16 in combination with PK-FLOW 20 can improve water use efficiency and nitrogen metabolism, reducing the impact of water stress.### Physiological Fruit DropPhysiological drop is common in avocados and can be mitigated with applications of Calcium 40%, which strengthens the cellular integrity of developing fruits, reducing premature drop.### Nutritional DeficienciesIron (Fe), zinc (Zn), and boron (B) deficiencies in alkaline soils are common. The application of Fulvex 50S and Micro Plus can improve the availability and absorption of these micronutrients, correcting deficiencies and promoting healthy growth.## Ecoganic Biostimulant Programme for Avocado by Phenological Phases

## Quantifiable Results with Ecoganic Biostimulants in AvocadoThe implementation of Ecoganic biostimulants in avocado cultivation has shown significant and quantifiable results. Producers have reported an increase in production between 15% and 35%, translating to an increase of up to 5 kg per tree in some operations. Additionally, fruit size has also improved, with an average increase of 10% in avocado size, which is crucial for the premium market.The internal quality of the fruit, measured by the percentage of fat content, has shown increases from 18% to 20%, leading to greater acceptance in demanding markets. Alternate bearing has also been significantly reduced, with a 25% improvement in annual production stability. Additionally, an extension in the post-harvest life of the fruits of up to 20% has been observed, which is beneficial for long-distance exports.## Organic Avocado in Europe and LATAM: Growing AreasOrganic avocado cultivation is booming in both Europe and Latin America, thanks to the growing demand for sustainable and high-quality products. In Spain, the regions of Málaga, Granada, and the Canary Islands concentrate approximately 15,000 hectares dedicated to avocado, benefiting from a favourable Mediterranean climate. Israel is also an important producer, known for its advanced irrigation techniques.In Latin America, Mexico leads global avocado production, with Michoacán as its main producing state. Peru and Colombia have emerged as important exporters, taking advantage of their tropical climates to grow avocados year-round. Kenya is another emerging player in the market, focusing on exports to Europe.To access international markets, certifications are essential. Exporters must comply with Regulation (EU) 848/2018 and USDA NOP to ensure their products are recognised as organic. In this context, Ecoganic products, which comply with these regulations, offer a significant competitive advantage.## Compatibility with Certified Organic AgricultureEcoganic products are fully compatible with certified organic agriculture, complying with Regulation (EU) 848/2018.
