Plant roots also need to breath if the soil is saturated the roots essentially suffocate.

Is your concern about water content of soil more about the negative affect of excess water on the seeds/seedlings or the ability of the wet soil to support heavy farm machinery during planting, or both?

The second. I am more interested in whether wet soil would be able to support heavy farm machinery during planting.

If that is the case you need to factor in the mechanical properties of different soil and the type of equipment used. For example, controlled traffic systems run the equipment down precisely the same tracks between rows so those become compacted and you don't have tractors trying to slog through the turned soil.

I doubt you can find a general value.  See for instance "rice paddy", or consider that in California, rice fields are flooded and then seeded by airplane: http://www.riceassociation.org.uk/content/1/14/cultivation---harvesting.html

Okay. Yes that is correct. Some crops would require more water like paddy which is flooded. What if I am talking just about soybean

# How much excess water prevents planting of a crop

(Asked by: username_0 on 2018-05-31)

In practice you *really* don't want to plant a field that is even close to capacity. Doing so will result in ruts, soil compaction, breakdown of soil structure and a large increase in fuel consumption.

One of the advantages of zero tillage systems is the ability to get out on the field in wetter (earlier in spring) conditions. All those roots help reduce the sheering between soil particles.
