What is the term for broadcasting dry urea fertilizer on an established tall fescue field?

The term for broadcasting dry urea fertilizer on an established tall fescue field is topdressing. This practice involves applying fertilizer to the surface of the soil or crop without incorporating it into the soil. Topdressing is particularly useful in established grass fields like tall fescue, as it allows for nutrient replenishment at a time when the plants are actively growing, enhancing their health and productivity.

This method offers several advantages, including minimizing soil disturbance and avoiding damage to the established root system of the grasses. In the case of tall fescue, which is a popular cool-season grass, topdressing can effectively ensure that the nitrogen needs are met during critical growth periods, promoting lush growth and improving overall forage quality.

Other terms used in the agricultural context have different meanings. Sidedressing typically involves applying fertilizer to growing crops in a band alongside the plant rows, whereas banding refers to placing fertilizer in a specific band at planting or shortly after. Foliar application involves applying nutrients directly to the leaves of plants, which is a different method focusing on quick nutrient absorption through the foliage.
