It doesn't seem right to cover up that nice black topsoil with all that sand! ------------- In Search Of: 1958 Allis Chalmers D17 Diesel serial #9643D |

| This looks like a pretty serious operation! So can you tell me why you would turn productive soil deep enough that it no longer can be? |

| i really want to hear the reason why also. good looking black dirt going under. |

| I think it's for drainage in soils that are high in organic matter, like peat. |

Evidently the sand layer is washed or blown in material which is separated by a layer of clay or hard pan that does not allow water to percolate out of it . So a wet heavy layer is above the clay layer - then sand below - then another restricting layer. Looking at the sand layer it looks like what is called modeled soil - sand or granular material that is stained with materials that were suspended in water - leaving the dissolved deposits behind as water slowly left soil. It can be a tell-tale sign of seasonally high water table or of old lake-bed or flooded area. If one encountered this while designing a drainage system for septic system - you could not install it in this soil.

There have been a line of limited production Cats coming into Australia from Californian irrigation deep plowing IIRC correctly. They're aimed here at cutterbaring/ blade plowing (root plowing I think it is called in US.
Tricked up in power and transmissions - I think they have D8 labels but are about D9's.
I can't seem to grab a reference for more info just now.

| I too would like to know more. Is the sand layer farely consistent throughout the field? Why not shallow up the plow to run just an inch or two into the sand and then leave the third dozed parked? |

Look closely at the pictures of the sand - you will see brown or gold coloring in it . This means water has stood in the sand and either slowly evaporated or percolated into soil, but at such a slow rate the dissolved material in the water stained the sand. This means a seasonal high water table that stands for a long time or continuous saturation of the soil. Below the sand layer there is more than likely another restriction that keeps the water in suspension above it . I did a percolation test in soils similar when designing a septic system for a church. It was raining lightly while doing the testing and water did not go down in my test holes but rose as the water in the soil flow across the sand layer seeking it's level rather than sinking into soil. ------------- Faith isn't a jump in the dark.

Wouldn't it make more sense to use a 5' single shank ripper on a big crawler?
