Many vegetable farmers have traditionally applied fertilizer while transplanting young seedlings, meaning they first dig a furrow, add the base fertilizer, and then plant the seedlings. While this method is believed to save fertilizer and avoid waste, it's actually not advisable. First, when transplanting melon seedlings from a nursery to the field, their root systems are weakened and less efficient at absorbing nutrients. If the fertilizer is placed too close to the roots, it can burn them, reducing the survival rate of the plants. Second, fertilizers need time to dissolve in the soil before being absorbed by the roots. If you apply fertilizer during transplanting, the nutrients may not be fully dissolved yet, so the seedlings won't be able to take them up effectively.
Therefore, it's better to apply the base fertilizer 10 to 15 days before transplanting, depending on the soil's fertility and the type of crop. This allows the fertilizer to mix thoroughly with the soil and begin breaking down. When the seedlings are transplanted, the nutrients will already be available for the roots to absorb quickly. Transplanting after the fertilizer has had time to settle also prevents it from forming concentrated piles that could harm the plants. This approach ensures healthier growth and higher survival rates for the seedlings.
In addition, proper timing of fertilizer application can improve overall nutrient uptake and reduce the risk of chemical burn. It’s important to consider the specific needs of each crop and the condition of the soil. Farmers should also monitor moisture levels, as water helps dissolve and distribute the fertilizer evenly. By planning ahead and following these best practices, growers can maximize the benefits of fertilization while protecting their young plants during the critical transplanting phase.
