Fencing on Agnomy

Barbed wire fencing typically costs about $1.25 to $6 per linear foot installed, while woven wire and high-tensile run higher. Price depends on fence type, number of strands, terrain, and the cost of posts, braces, and gates. Larger continuous runs usually cost less per foot than short or broken sections.

Cattle are commonly contained with 4 to 5 strand barbed wire or woven wire, often 4 to 5 feet tall on wood or steel posts. High-tensile and electric fencing are also used for rotational grazing. The best choice depends on herd pressure, budget, and whether the fence is permanent or movable.

Fence posts are generally set about a third of their length into the ground, often 2.5 to 3 feet deep, with corner and brace posts set deeper for strength. Depth depends on soil, post height, and wire tension. Solid corners and braces matter most because they carry the load of stretched wire.

A well-built farm fence often lasts 20 to 30 years or more, with high-tensile and quality woven wire on durable posts at the longer end. Lifespan depends on materials, soil, moisture, and livestock pressure. Routine repair of loose wire and damaged posts greatly extends the life of a fence line.
