Phone calls have been coming in regarding applying an in-furrow starter fertilizer at corn planting. An in-furrow starter is commonly called a “pop-up” fertilizer, and is applied in the seed furrow (in-furrow). This allows for ease of application and placing the nutrients close to the germinating seed which allows the seedling to have easy access to nutrients. A good in-furrow fertilizer will contain a high percentage of phosphorus along with some nitrogen, but could also contain sulfur, potassium, or micro-nutrients.
