Using variable rates on the farm

Major changes in farming practices always take time, and precision agriculture is no exception. Zero till first caught producers’ attention in the late 1970s, but it took more than 20 years to become mainstream. Despite the obvious benefits of satellite guidance and autosteer, it took a decade for that technology to become mainstream. Farmers began […] Read more

Even without the strobe turned on, the basic LED mounted at each nozzle provides an accurate view of what the spray pattern looks like.  With the strobe mode operating, it’s possible to study the pattern even in broad daylight.  Anderson says nozzle checking can be done in your house during the winter. In this photo, it looks like he’s checking nozzles in his basement.  |  Bryan Anderson photo

Make your spray droplets glow in the dark

Farmers who like the way a disco strobe does that freeze-frame trick on their dance partner will love the way it stops action on their spray pattern. Moving those strobe lights from the disco to the spray boom might give them an entirely new perspective on what they’re doing in the field at night. Many […] Read more

The Pattern Master concept is simple yet effective.  It’s a brush that hangs on the front side of the nozzle to cut wind shear.  In doing so, it increases Dropletscan software readings by as much as 92 percent compared to nozzles without the brush.   |  Pattern Master photo

Brush your cares away, go spray

A Wisconsin inventor hopes farmers will be interested in spending $4,000 to equip their spray booms with a new device he says can increase target coverage by 92 percent. Kurt Kamin has merged his experience as a sprayer operator with his pilot experience to develop a brush that hangs in front of each nozzle to […] Read more


Spray scientist says think outside the tip

Application specialist Tom Wolf says we’ve hit the limit with nozzles when it comes to reducing spray drift. It’s now time to think about wind shear. “Wind shear has two powerful impacts: it makes the spray finer and it sucks the little droplets out of the spray cloud,” says the Saskatoon spraying systems researcher. “Those […] Read more

The right tire for the right soil and load

We know different combinations of tires and inflation cause different degrees of soil compaction, but until now there was no way to put a number on it. The Scandinavian soil science project called Poseidon has given The Western Producer its readers access to an interactive calculator called Terranimo, which lets producers figure out that elusive […] Read more


When does big become too big?

Boom builders and boom buyers agree that bigger is better, especially in Texas where everything is super-sized. However, Texan Ron Boyd argues that there may be times when one size smaller is better than one size larger. Three months ago, the boom manufacturer and retailer introduced a return on investment calculator that accounts for 20 […] Read more

The biggest tire technology breakthrough in decades comes from the little-known Czech Republic company Mitas. It may look like a round rubber tire from a distance, but when viewed from up close to the footprint it looks more like a flat rubber track.  |  Mitas photo

Shape-shifting tire mimics rubber track

Reinforced sidewall construction achieves 167 percent better lateral stability so it can flatten under heavy loads

Whether farmers prefer round rubber pneumatic tires or flat solid rubber tracks depends largely on their soil and precipitation. The industry offers a comprehensive lineup of tires and tracks to keep everyone happy. After all, there is no in between or compromise. Or is there? Well, maybe there is. Mitas, the little known tire company […] Read more

Mitas tires use ‘mini-track’

Farmers who’ve switched from tires to tracks all seem to miss one thing: air. Tracks jolt man and machine, while tires let farmers ride on a cushion of air. “Air supports the tractor,” says Firestone field engineer Wayne Birkenholz. “A tire is nothing more than a rubber container holding air.” Ideally, farmers could buy implements […] Read more


Tires allow for larger load, same footprint

Firestone’s new Advanced Deflection Design agricultural tires are engineered to fit the increased flexion (IF) and very high flexion (VF) categories for agricultural tires. Field studies at the Firestone Research Farm in Ohio show that AD2 tires yield a four percent savings in fuel and a five percent savings in time when compared to equivalent […] Read more

On the left, this core sample was taken from soil that had never been disturbed or compacted by machinery. It shows an abundance of macropores measuring 0.6mm in diameter and larger.  The macropores are aligned vertically as well as horizontally so water infiltrates down into the soil and out laterally to reach plant roots.  
At right, this core was pulled from soil that had been driven over by a sugar beet harvester 14 years prior to sampling, but had not been impacted by machinery since that event.  Not only has the number of the vertical macropores been reduced, but more importantly, the horizontal passages that allow water to be distributed laterally through the soil have been all but eliminated.  Although both cores were pulled from identical loamy soils in an area with nordic winters, 14 years of frost have not loosened or rejuvenated the compacted soil. Both soil cores measure 20cm high and 20cm in diameter and were pulled from a depth of 25cm to 45cm.  |  Dorthe Wildenschild, Oregon State University

CT scan tech used to check soil health

The penetrometer has been the primary instrument for measuring soil compaction since its introduction in 1905. More recently, Scandinavian soil scientists have used hospital CT scans for a more accurate measurement to clearly depict and quantify soil structures. One of the pioneers in this area is Dorthe Wildenschild, a researcher in Oregon State University’s chemical, […] Read more
