Fertilizer Knives 101

Maximizing yield is critical for your farm’s success. While the health of many crops is determined before planting occurs, some require an extra boost after seeding. Learn more about the importance of fertilizer knives and the benefits of sourcing your ag equipment from RangeLine Group.

What Are Fertilizer Knives?

Growers use a fertilizer knife to inject additional fertilizer into corn to enhance growth and yield. Adding another layer of fertilizer to corn stalks is called side-dressing and enables farms to maximize uptime and productivity.

What Are the Main Types of Fertilizer Knives?

Regardless of your farming technique, making sure your crops receive the necessary nutrients is critical for a successful growing season, and using the right fertilizer knife maximizes your efficiency. Soil conditions as well as the methods and type of fertilizer you use all determine which knife is right for your farm. Here are the three main types of knives that growers use:

Dry Fertilizer Knives

Dry fertilizer knives are ideal for organic farms that want to avoid using liquid fertilizer on their crops. These knives push the dressing into the ground, where it turns into nitrogen to increase crop yield.

Liquid Fertilizer Knives

Liquid fertilizer knives allow growers to efficiently add nutrients to their corn crops. These knives feature a tube that injects fertilizer into the root system to boost the next stage of development.

Backswept Fertilizer Knives

Backswept fertilizer knives are recommended for growers working with looser soil conditions. These knives are available in curved and straight profiles and prevent residue from building up on the shank.
