2. What Are Organic Fertilizers Exactly and How Do They Work?

Organic fertilizers are products of natural origin, derived from organic matter of animal, plant, or mineral origin, used to nourish crops naturally and sustainably. Unlike chemical or synthetic fertilizers, which are mineral-based and release nutrients quickly, organic fertilizers release nutrients in a gradual and progressive manner, mimicking natural soil processes. Their main mechanism of action is not only to provide nutrients directly to the plant but also to improve the overall health of the soil, increasing its organic matter, biological activity, and nutrient and water retention capacity. By enriching the soil with organic matter, organic fertilizers feed the soil microbiota (bacteria, fungi, etc.), which in turn breaks down organic matter and releases nutrients in a form that plants can assimilate. This natural process ensures balanced and sustainable nutrition in the long term, creating a living and fertile soil that benefits your crops and the environment.

3. Types of Organic Fertilizers: A Range of Natural Options

There is a wide variety of types of organic fertilizers, each with its own characteristics, advantages, and recommended uses. Knowing the types of organic fertilizers available will help you choose the best option for your crops and needs. We can mainly classify them into:

4. Key Benefits of Using Organic Fertilizers in Your Crops

Choosing organic fertilizers to nourish your crops offers a wide range of benefits, both for your plants and for the environment and sustainability of your agricultural operation:

• Manures: One of the most traditional and complete organic fertilizers. They come from the feces of animals (cattle, horses, sheep, chickens, etc.) and provide organic matter, nitrogen, phosphorus, potassium, and micronutrients. It is important that they are well composted to avoid phytotoxicity and weed problems. There are different types of manures depending on the animal of origin, varying in composition and nutritional richness.
• Compost: The result of the controlled decomposition of organic matter (plant residues, kitchen scraps, etc.). Compost is an excellent soil improver, providing organic matter, nutrients, and beneficial microorganisms. It can be made homemade or purchased as commercial compost of quality.
• Worm Humus: Considered one of the best organic fertilizers due to its nutritional richness and benefits for the soil. It is the result of the d digestion of organic matter by earthworms. Worm humus improves soil structure, water and nutrient retention, and provides a large amount of beneficial microorganisms.
• Guano: Excrement from seabirds or bats, very rich in nitrogen, phosphorus, and micronutrients. Guano is a powerful organic fertilizer ideal for nutrient-demanding crops, but it must be used with caution due to its high concentration. There are different types of guano depending on its origin and composition.
• Green Manures: Crops of plants (legumes, grasses, etc.) that are sown and then mowed and incorporated into the soil as fresh organic matter. Green manures improve soil structure, provide nutrients (especially nitrogen in legumes), and prevent erosion.
• Rock Meals: Powders of ground rocks (basalt, dolomite, phosphorite, etc.) that provide minerals and trace elements to the soil gradually. Rock meals are slow-release organic fertilizers ideal for enriching mineral-poor soils.
• Commercial Liquid Organic Fertilizers: Liquid formulations based on plant extracts, algae, worm humus, or other organic materials. Liquid organic fertilizers are easy to apply through irrigation or foliar spraying and offer quick and balanced nutrition. Ecoganic NITROTECH 2.5% Liquid is an example of a high-quality liquid organic fertilizer, ideal for complementing base fertilization and providing an extra dose of nitrogen naturally.

• Improves Soil Health and Fertility in the Long Term: Organic fertilizers enrich the soil with organic matter, improving its structure, aeration, water and nutrient retention capacity, and fostering microbial life. A healthy soil is the foundation for healthy and productive crops in the long term.
• Balanced and Sustainable Nutrition for Plants: Organic fertilizers release nutrients in a gradual manner, avoiding nutritional imbalances and ensuring constant and sustained nutrition throughout the crop cycle. This translates into stronger, healthier, and more resilient plants.
• Increased Plant Resistance to Stress and Diseases: A healthy soil and balanced nutrition strengthen the immune system of plants, making them more resistant to pests, diseases, and abiotic stress (drought, temperature, salinity, etc.). This can reduce the need for pesticides and other chemical treatments.
• Improves the Quality and Flavor of Food: Foods grown with organic fertilizers often have better flavor, aroma, and nutritional quality. Balanced nutrition and soil richness are reflected in the quality of the harvest.
• Benefits for Soil and Aerial Biodiversity: Organic agriculture and the use of organic fertilizers promote biodiversity in the soil (microorganisms, earthworms, etc.) and in the agroecosystem in general (beneficial insects, birds, etc.).
• More Sustainable and Environmentally Friendly Agriculture: Organic fertilizers are a more sustainable and environmentally friendly option than chemical fertilizers, as they reduce soil and water pollution, minimize the environmental impact of production and transport, and contribute to the circular economy by utilizing organic by-products.

5. How and When to Use Organic Fertilizers Correctly? Step-by-Step Guide

To use organic fertilizers correctly and achieve the best results, it is important to follow a series of steps and recommendations:

1. Prior Soil Analysis: Conducting a soil analysis is essential to understand the characteristics of your soil (pH, organic matter, available nutrients, etc.) and determine the specific fertilization needs of your crops.
2. Calculation of Doses and Nutrient Needs: Once you know the soil analysis and the crop needs, calculate the doses of organic fertilizer necessary to provide the required nutrients. Consult the manufacturer’s recommendations and adjust the doses based on your experience and observation of the crops.
3. Methods of Application: Organic fertilizers can be applied in various ways:
   • Surface Application: Spread the fertilizer over the soil surface and then lightly incorporate it with a rake or hoe. Ideal for solid fertilizers such as manure, compost, or granules.
   • Buried Application: Incorporate the fertilizer into the soil during land preparation or at planting. Recommended for slow-release fertilizers and to ensure that nutrients are available in the root zone.
   • Fertigation: Apply liquid organic fertilizers dissolved in irrigation water. Ideal for quick and localized nutrient contributions, especially during high demand phases.
4. Application Frequency: The frequency of organic fertilizer application will depend on the type of fertilizer, the crop, and the growth phase. Slow-release fertilizers (manure, compost) can be applied once a year or at the start of the crop. Liquid fertilizers may require more frequent applications during the crop cycle, especially at times of higher nutritional demand (vegetative growth, flowering, fruiting).
5. Precautions and Tips:
   • Use quality organic fertilizers and those with organic certification if you are looking for organic production.
   • Compost or ferment manures properly to avoid problems.
   • Do not exceed the recommended doses, as an excess of organic fertilizer can also be harmful.
   • Combine different types of organic fertilizers for more complete and balanced nutrition.
   • Observe your crops and adjust fertilization according to their needs and responses.
   • Consider complementing organic fertilization with organic biostimulants to enhance plant growth and resistance.
