Filling a ditch/valley

[future_vision]

I have a piece of rolling land and I am at a point where I am considering filling a low point on the land (pictures below). What I am trying to determine is what is best to fill it with. I have a variety of materials handy. Everything from dirty fill(loam, twigs, small rocks, roots), to regular loam to a sand loam mix etc. The dirty fill is by far the largest amount of material I have but my concern is if it gets saturated it will be undriveable with my 60hp tractor. What would you use? I'm including images of the materials I have as well.

What do you want to do with it after it's filled?

The question is why is that low spot there? When it rains does it flow a lot of water? If it does anything you put in there may erode away. Filling it in and adding some rip rap where the water would speed up would work.

I have a bunch of areas that I've filled and that I'm still filling on my land. For the smaller ditches caused by erosion, I put in rock, busted up concrete and bricks to stop the erosion and catch the dirt. Over the years I've forgotten where those areas are after the grass grew in.

For the bigger areas I fill them with the ash from my burn pile. I try to clean up my burn pile once a year. The Ash seems to be mixed with a bunch of dirt which is always a mystery for me since I pick up all the branches and debris with a grapple, but after a year, it's a huge pile of dirt and ash mixed together. I have a one-yard bucket on my backhoe, and it can take 20 to 30 loads to clean it all up. I've been working on a very big area for years now. I'm probably halfway there. This area is close to the property line and the fence. I can't mow along the fence in this area with my batwing, but in the area that I have filled it, I can. Once I get the ditch about a foot from being full, and I've driven over it so many times that it's compacted, I add dirt to create the top layer so grass will grow there.
