Using banded fertilizer for corn production

Using banded fertilizer for corn production

Dry materials can usually be blended so a product with a higher sulfur concentration can be provided. In such situations, a dry starter is sometimes less expensive because it can supply the needed sulfur while being applied at a lower rate. Some cautions. The pop-up placement is an effective method for applying phosphate and potash fertilizers.
