Topband: radial depth

[Roy]

About,

"Hi all - can anyone tell me if there is a depth in ordinary soil that is 
too deep  for radials.

I have a field which is currently growing wheat - when we harvest this year 
I am thinking of digging down approx 1m and laying a new radial system.

At this depth when I plough I will not touch the radials system - in fact 1m 
is really overkill unless I use the subsoiler which may get a bit close."

Thanks from Dave G3RCQ


Dave,

Yes. Most books recommend no deeper than a "few inches" because if radials 
are beneath very much soil, every benefit of using radials is lost through 
losses above them.
