Safety First When Planning Deep Tillage or Earthwork: Call Before You Dig!

Dec 08, 2021

By DeAnn Presley

With harvest complete and some mild temperatures heading into winter, farmers might take to the field for deep tillage such as ripping, or to make earthwork repairs around the farm. A few days before you want to start these activities, it’s worth a call to 811 for your safety and to prevent expensive damage to underground utilities. The website, http://call811.com, has easy-to-follow instructions for requesting this free service and detailed information concerning why you need to know what’s below.

A video produced by Marathon Oil tells the story of a farm family and their close-call with a pipeline when installing tile drains. The landowner knew where the pipeline entered and exited the field, and they assumed the pipeline was straight— it wasn’t. Watch this 6-minute, eye-opening video for the whole story; https://youtu.be/oe-iknpYzF8.

Sadly, fatal accidents do happen in soil excavations. If you dig any trenches or soil pits, safety should be considered from the very beginning of the project. Soils with sandy textures are more susceptible to a collapse than soils with a higher clay content. If standing water is present in the pit, the walls are more apt to collapse. Digging in soils that have been disturbed before, such as digging next to a hydrant or foundation, for example, means that the soil is far less stable than you might expect if that soil had never been disturbed before.

There are Occupational Safety and Health Administration (OSHA) guidelines on excavation safety, such as when it is necessary to shore the walls of a soil pit or trench. One important consideration is soil should be piled a minimum of 2 feet away from the walls of the trenches for two reasons:

Soil clods or excavating tools could roll back into the trench and cause injury to occupants.
Helps reduce the risk of a trench collapse by keeping the weight of the soil piles away from the trench edges.

Even if a soil pit is 5 feet deep or less, it is a good idea to angle the edges of the soil pit, especially if the texture is sandy, the soil is wet, or if the soil is otherwise unstable. This does create more disturbance, but if it prevents an accident, it’s worth it.

Video: Spring 2026 weather outlook for Wisconsin; What an early-arriving El Niño could mean

Northeast Wisconsin is a small corner of the world, but our weather is still affected by what happens across the globe.

That includes in the equatorial Pacific, where changes between El Niño and La Niña play a role in the weather here -- and boy, have there been some abrupt changes as of late.

El Niño and La Niña are the two phases of what is collectively known as the El Niño Southern Oscillation, or ENSO for short. These are the swings back and forth from unusually warm to unusually cold sea surface temperatures in the Pacific Ocean along the equator.

Since this past September, we have been in a weak La Niña, which means water temperatures near the Eastern Pacific equator have been cooler than usual. That's where we're at right now.

Even last fall, the long-term outlook suggested a return to neutral conditions by spring and potentially El Niño conditions by summer.

But there are some signs this may be happening faster than usual, which could accelerate the onset of El Niño.

Over the last few weeks, unusually strong bursts of westerly winds farther west in the Pacific -- where sea surface temperatures are warmer than average -- have been observed. There is a chance that this could accelerate the warming of those eastern Pacific waters and potentially push us into El Niño sooner than usual.

If we do enter El Nino by spring -- which we'll define as the period of March, April and May -- there are some long-term correlations with our weather here in Northeast Wisconsin.

Looking at a map of anomalously warm weather, most of the upper Great Lakes doesn't show a strong correlation, but in general, the northern tiers of the United States do tend to lean to that direction.

The stronger correlation is with precipitation. El Niño conditions in spring have historically come with a higher risk of very dry weather over that time frame, so this will definitely be a transition we'll have to watch closely as we move out of winter.
