[QUOTE="Texasmark, post: 1502684, member: 27848"] All types of soils, farming practices and numerous subsoilers. I had an airline pilot farmer nearby with a 105 White and a 3 shank that looked to be 3' long. I like the Hay King Pasture renovator and is my primary "plowing" tool which I run around 8", give or take, deep. On farm sites I read where folks with places such as yours do what you are intending to do and get positive results.....makes sense. I'm remembering the author of the piece was running pretty deep....forget just how deep. ------------- What is plow pan? I don't technically know but expect it is the interface of soil (clay) that goes untouched from year to year adjacent to soil that get things that go say 4-6" deep year to year. Since 6" is where most roots grow and plowing costs money, why go any deeper??????? I'm in Houston Black Clay, some of the nastiest stuff you want to fool with when "it" doesn't want to be bothered. In the summer it cracks open and some of the cracks are 6" across at the top and as long as you care to follow them in lateral length. I have attempted to find the bottom and gave up at 6 feet on some of the larger ones. These cracks allow nutrients and moisture to penetrate well below the root zone and allow water to be stored for clay's bright spot....providing moisture for late summer crops. When the rains come and fill up the cracks the clay essentially melts and becomes one gooey, muddy, blob of a mess.
