\"\"<\/figure>\n\n\n## Organic Maize in Europe: Market Opportunities\n\nThe cultivation of organic maize in Europe is experiencing significant growth, with cultivated areas reaching 700,000 hectares according to recent data. This increase is primarily due to the rising demand for organic products, especially in the livestock sector, where organic feed is increasingly sought after. Organic maize, which does not use synthetic chemical products, becomes an ideal option for the production of feed intended for organic livestock, complying with the strict regulations of Regulation (EU) 848\/2018.\n\nThe price of organic maize is notably higher than that of conventional maize, with an increase ranging between 50% and 80%. This price differential, coupled with growing demand, makes organic maize an attractive option for farmers. In Spain, the regions of La Rioja, Navarra, and Catalonia stand out for their production of organic maize, while in France, Romania, and Hungary, the crop has also found a significant niche.\n\n## Agronomy of Maize: Foundations for Success\n\nFor the successful cultivation of organic maize, it is essential to understand its agronomic requirements. Maize germination requires temperatures above 10\u00b0C, with the optimal range being between 18\u00b0C and 22\u00b0C. Regarding planting density, it is recommended to establish between 70,000 and 85,000 plants per hectare to maximize production. The nutritional needs of maize are considerable, requiring approximately 250 kg\/ha of nitrogen, 90 kg\/ha of phosphorus, and 250 kg\/ha of potassium to achieve yields of 12 tonnes per hectare.\n\nCrop rotations are fundamental in organic agriculture to maintain soil health and break the cycle of pests and diseases. A rotation including cereal, legume, and maize is recommended, which not only improves soil structure but also optimizes nutrient use.\n\nThe phenology of maize can be divided into several critical stages:\n\n“`html\n\n \n \n \n \n \n \n \n \n \n \n \n

Among the most common diseases are Fusarium verticillioides, causing pink rot, and Ustilago maydis, responsible for smut. Additionally, the corn borer, Ostrinia nubilalis, poses a significant challenge. Without the use of herbicides, competition with weeds is another critical problem, especially during the R1 flowering phase, the most vulnerable to water stress.\n\nMicronutrient deficiencies such as zinc (Zn) and manganese (Mn) are common in organic soils. Biostimulants play an essential role in mitigating these issues. These products enhance nutrient absorption and strengthen the plant’s natural defenses. For example, biostimulants rich in amino acids and fulvic acids, like Fulvex 50S, can improve Zn and Mn uptake, promoting healthy crop development.\n\n## Ecoganic Biostimulant Programme for Maize\n\nAn effective biostimulant programme is crucial for maximizing the yield of organic maize. Ecoganic offers a range of products designed for each phase of maize development:\n\n\n \n \n \n \n \n \n \n \n \n \n \n

Under normal conditions, an increase of 800 to 1500 kg\/ha has been recorded, while in years of stress, the increase can reach up to 2000 kg\/ha. Additionally, an improvement in test weight of 2 to 4 kg\/hl and an increase in protein content of 0.5% to 1% have been observed. Harvest moisture percentages remain comparable to standards, ensuring grain quality.\n\nThese results come from trials conducted in various regions, including Spain, France, and Argentina, confirming the efficacy of Ecoganic biostimulants under different climatic and soil conditions.\n\n## The Critical Factor: Biostimulants in R1 Flowering\n\nThe R1 flowering phase is critical for maize, as the 7 to 10-day pollination window determines up to 60% of the final yield. During this phase, biostimulants play a vital role in reducing thermal stress, improving pollen viability, and synchronizing the emergence of tassels and silks. Products like Calcium 40% and PK-FLOW 20 are essential to ensure effective pollination and optimal grain development.\n\n## Organic Maize by Geographic Areas\n\nIn Navarra and La Rioja, irrigated maize with a FAO cycle of 600-700 is predominant, while in Catalonia and the Ebro basin, conditions favour similar cycles. In France, especially in the Midi-Pyr\u00e9n\u00e9es region, organic maize is also booming, adapting to shorter cycles (FAO 400-500) in central Europe.\n\nEach region presents specific challenges, and the Ecoganic biostimulant programme adapts to these conditions, optimising crop yield based on climate and soil characteristics.\n\n## Compatibility with Certification and Organic Rotations\n\nCompliance with Regulation (EU) 848\/2018 is essential for the certification of organic maize. This regulation requires crop rotations and limits the use of fertilizers to those of organic origin. Ecoganic biostimulants are designed to enhance nutrient use efficiency and the soil’s cation exchange capacity (CEC), promoting a more favourable environment for beneficial microorganisms and ensuring compliance with organic standards.\n\n## Frequently Asked Questions about Biostimulants for Maize\n\n\nPREGUNTA: \u00bfQu\u00e9 ventajas ofrecen los bioestimulantes Ecoganic en el cultivo de ma\u00edz ecol\u00f3gico?\nRESPUESTA: Los bioestimulantes Ecoganic mejoran la absorci\u00f3n de nutrientes, fortalecen las defensas naturales de las plantas y aumentan el rendimiento.
