Application Guide and Doses

The correct application of organic fertilizers is crucial to maximize their effectiveness. Below are recommendations on how to apply these fertilizers to vegetables:

1. Soil Preparation

Before applying the fertilizer, it is essential to properly prepare the soil. It is recommended to conduct a soil analysis to determine its specific needs. This will allow for effective adjustment of fertilizer doses. A typical soil analysis includes the evaluation of pH, organic matter, available nutrients (nitrogen, phosphorus, potassium), and soil texture. According to INTA, proper soil preparation can increase the efficiency of organic fertilizers by 40%. The incorporation of organic amendments such as manure or compost can improve not only fertility but also soil structure, facilitating root development. Additionally, well-prepared soil favors the activity of beneficial microorganisms that decompose organic matter and release nutrients gradually.

2. Recommended Doses

The doses of organic fertilizers can vary depending on the type of crop and soil conditions. Below are general guidelines:

• Leafy vegetables (e.g., lettuce, spinach): 2-3 kg of organic fertilizer per 10 m².
• Fruiting vegetables (e.g., tomato, pepper): 3-5 kg of organic fertilizer per 10 m².
• Roots (e.g., carrot, beet): 3-4 kg of organic fertilizer per 10 m².

These doses can be adjusted based on the results of the soil analysis. It is advisable to apply the fertilizer before planting or during the crop’s growth stages. For example, for tomato cultivation, an initial application of 4 kg of mature compost per 10 m² followed by an application of 2 kg mid-cycle may be optimal. In leafy vegetable crops, it is useful to make an additional application of 1 kg at 4 weeks to encourage robust growth. In an experiment conducted in the province of Buenos Aires, it was observed that applying a dose of 3 kg of compost per 10 m² in leafy vegetables increased yield by 18% compared to the control.

Example of Doses in Vegetable Cultivation

In a lettuce crop, 2 kg of organic fertilizer can be applied at the time of planting. Subsequently, a second application of 1 kg can be made at 4 weeks of growth to stimulate vigorous growth. Studies have shown that applying in two stages can increase yield by 15% compared to a single application. In an experience conducted in La Plata, producers who applied organic fertilizers in two stages reported lettuces with a size 20% larger and better flavor, which translated into higher prices in the market.

3. Application Methods

Application methods can vary, but here are two common approaches:

• Incorporation into the Soil: Mix the fertilizer with the soil before planting. This method is ideal for improving nutrient availability in the soil. It is recommended to till the soil to a depth of 15-20 cm to ensure proper mixing. The incorporation of organic fertilizers into the soil can improve the availability of nutrients such as nitrogen and phosphorus, which are essential for plant development. A trial in the Pampas region showed that incorporating compost increased the levels of available nitrogen in the soil by 25% compared to the control.
• Foliar Application: Prepare a diluted solution and apply directly to the leaves of the plants. This method allows for rapid nutrient absorption. It is advisable to make the application in the afternoon to avoid evaporation and improve absorption. A study in Córdoba showed that foliar application of an organic fertilizer based on algae increased leaf growth by 20% compared to the control without fertilizer. Foliar application can also be useful for correcting specific nutritional deficiencies, such as lack of iron or magnesium. For example, applying iron chelates in tomato crops has been shown to improve the color and size of the fruits.

Considerations on Application Timing

The timing of application is also crucial. It is recommended to apply organic fertilizers during periods of high biological activity in the soil, such as spring and early summer, when temperatures are moderate and moisture is adequate. This maximizes the decomposition of organic matter and the release of nutrients. On the other hand, applications in autumn can help improve soil quality and prepare the ground for the next growing season. An analysis conducted in Entre Ríos showed that crops receiving organic fertilizers in autumn showed a 15% increase in production in the following season.
