Compaction worse with wide tyres?

[Grassman]

Why do wide tires cause deeper soil compaction? Science explains - Future Farming

A broader tire pushes its ground pressure deeper into the soil. This is why.

More compaction in the gateway?

Can you explain the theory

 

[Bury the Trash]

Its physical fact. and science.
all wider tyres do is spread load over a wider area on the surface but the trade off isdown below it takes the weight deeper . where it is potentially harder /longer winded to get out

weight is weight it cant be magicked away what ever weight the tractors /machinery whatever is its still the asame weight on the soil whatever size wheels are.

despite what others say agaisnt that fact , becasue it doesnt suit their narrative.

this isnt exactly the science bit but

Avoiding Soil Compaction

The increasing size of farm equipment may cause significant soil compaction that can negatively affect soil productivity as well as environmental quality.

That is basically what it says. So you are better with narrow tyres so you will see what damage you are doing perhaps?

Just tried again and it works

well at least you arent kidding yourself i suppose.
another example of tail chasing we sometimes do is fitting dual wheels that add etra weight to the whole rig, does make a leveller seed bed or less routs in grass early spreading for later mowing mind you.


sveral little skippy robotic remotcontrolled 'tractors' or even drones for spraying and spreading would be the ideal future ?

That's the trouble needs some hardcore in the gateway ...

way back in my rt days I went to a 'soils day'...bods taking it ...at one stage...talking about research that seemed to indicate a bigger circumference of tyre produced less compaction ....didn't make much sense to pleb like me....wt on ground for less time??...dunno what became of it....I went 'Turnip taliban" and left rt shortly after

thats a classic example of why the whole farm assurance subject angers me, people calling the shots /assuming who have far less Knowledge about the job than a lot of farmers actually do.

Bigger circumference equals longer footprint, so bigger circumference can be as effective as bigger width.

 

[betternextyear]

Its weight that causes compaction, width is a minor component of the problem. Once you get to 10 tonnes on your axle , changing tyre size isnt going to help

The only time it was noticeable on my soils was when using a contractor with a six row self propelled beet harvester on wide tyres. The field was left level but the soil was tighter further down the profile. It was still better than chewing ruts with a rapide tanker and 2wd tractors on Ferguson trailers.

That's what I assumed. Do you want compaction and ruts near the surface or compaction deeper but less surface damage.

With tracks extending the theory quite literally, further

Over time the deeper compaction was not an issue. The surface rutting caused by the old system needed ploughing to get level again. Quite often this compaction was deeper than 12” though. Subsoilers on the plough helped but often a shakerator was needed the following year. I currently use wide tractor tyres for most operations and try and keep off the fields when conditions are unsuitable. Not always possible in the current times.

When trying to compact with a vibrating roller, low speed and vibration are what works more than weight and width.

The reason why potato and beet harvesters seem worse maybe and why the combine sinks when unloading on the headland with the vibration form the sieves.

Higher speed defiantly reduces compaction significantly in my experience.
