Calibrating Forage Seeding Equipment

Oat and ryegrass seeds mixed in the main seedbox. Smaller ryegrass seed increases the speed of the flow compared to oat only.

Establishing forages from seeds often requires precision equipment to achieve specific seeding rates for a proper pasture stand. Most pieces of equipment have calibration charts, which are useful guides for making an initial setting. However, due to variations in seed size, purity, moisture content, equipment performance, ground speed, and other factors, calibrating equipment prior to each use is recommended. This 5-page document discusses a few calibration techniques for drills and broadcast spreaders.

Forage-Based Heifer Development Program for North Florida

Young heifers at the Range Cattle Research Station. These beef cows are all at least 3/4 Angus. They are part of an attempt to create a white Angus breed. During the summer the white cows, coined "white Angus" by the researchers in Ona, have a body temperature that is one degree cooler than the traditional black Angus. UF/IFAS Photo: Sally Lanigan.

Developing replacement heifers to become productive females in the cow herd is a tremendous investment in a cow-calf operation that takes several years to make a return. Fortunately, there are several options to develop heifers on forage-based programs that can help reduce costs while meeting required industry performance targets. This new 4-page document proposes a model for replacement heifer development based on forage research trials at the UF/IFAS North Florida Research and Education Center (UF/IFAS NFREC) in Marianna, FL.
