Why is Weed Control Important to your Electric Fence System?
Is your electric fence system not working properly? Heavy weed conditions could be your problem. Let’s talk about the importance of weed control around the fence line. Weeds, although quite unsightly, can also be drawing a significant amount of energy from your fence line. When weeds come in contact with an electric fence, voltage and amperage are drained from the fence to the earth. In heavy weed conditions, much of the joule output produced from the energizer could be drawn to the earth; which could short out your fence.
In dense weed conditions, your fence has a heavy fence load and low resistance. The specific amount of fence load is measured in ohms, the standard measurement of electrical resistance, and ohms is an inverted scale. Therefore, low resistance equals low ohms and a heavy fence load (a lot of weeds on the fence). So the lesson is that weeds can jeopardize the effectiveness of your electric fence system.
Low impedance energizers have the capability of increasing their energy output as fence load increases. This means as weeds touch the fence and draw voltage and amperage to earth, a low impedance energizer will begin to produce higher amounts of energy (joules). These higher energy levels will overcome the voltage and current loss caused by the weeds, and maintains energy levels on the fence line. As long as the wire remains in contact with the energizer, the energy can push past weeds or vegetation to keep the fence hot.
Zareba® low impedance energizers are designed to reach their maximum energy output at low resistance levels, or low ohms. This allows our energizers to produce their maximum energy output when it is needed most; when heavy fence load is on the fence line.
Weed control is still important to your electric fence system, even if you purchase a low impedance energizer. Weed control methods to consider:
- Repair weakened areas near your fence line were weeds have a chance to take hold.
- Reduce foot traffic near your fence line. When soil gets compacted, grass has trouble growing, which poses to potential for weed growth.
- Mow grass at three inches or higher. This can help weaken weeds by shading them out.
- Apply organic weed killer, like Safer® Brand or chemical weed killer.
- Pull or use a weed whacker near the fence line and posts.
You have several options to consider when overcoming the weed battle. Which methods do you use to control weeds on your farm?
