What is it called when fertilizer is applied a little deeper and to the side of where the seeds are planted?

1. Banding

2. Side dressing

3. Split application

4. Top dressing

The correct answer is: Banding

Applying fertilizer a little deeper and to the side of where seeds are planted is referred to as banding. This technique enhances nutrient availability to the crops while minimizing competition with the seeds for nutrients in the early growth stages. By placing the fertilizer in bands, it provides a concentrated source of nutrients that encourages strong root development without interfering with seed germination. Banding is especially effective as it can improve nutrient uptake efficiency and reduce losses due to leaching or runoff. In contrast, side dressing involves applying fertilizer to the sides of growing plants during the growing season, split application refers to giving a portion of fertilizer at different times rather than all at once, and top dressing entails applying fertilizer on the soil surface after the crop has been established. Each of these other methods has its own specific timing and purpose, which differentiates them from the banding technique.
