Need help identifying plants

[EWilson99]

Does anyone know what kind of plants these are? They seem to grow on agricultural land that has not been harvested, and they'll grow fairly quickly while taking up a large amount of space.

I was hoping to get rid of these as they take up a lot of space on the field's borders, and as we plant trees on this field throughout the next couple of years, I'm hoping that these thorn bushes/plants don't spread in between the trees.

kinda looks like black locust, but, would help to know what part of the world you are finding it. 

By the, welcome to the forum, pull up a stump and sit awhile.

maybe prickly ash

Since it is old field I would guess black locust or prickly ash. Not a true ash since it is alternate branched.

Has anyone ever seen fine thorns on white ash? I have, they are sharp, but very short. Like very hard/stiff raspberry thorns, only more sparse. Never see it documented. There is a lot of ash in the woods up here, so I suspect some variations. Only native thorn bushes up here are plum, rose and hawthorn.

maybe prickly ash

Yup, just looked it up, and the little fruits that are found on the field every year belong to the prickly ashes. We are in Eastern Ontario, so it seems to be in its native range.

Now, the question is how to get rid of hundreds of these things everywhere.....

Mow, mow, mow.

The issue is that there are many of these things that are fully grown across the property. I've used one of those big branch cutters in order to cut down most of these plants at the base of their trunks, but I just don't have a massive tool that could get all of the roots excavated. 
It's why I'm hoping that the plantation of trees can help stop the growth of prickly ash. I don't think it'll do much of anything, but I just don't want the prickly ash to spread and make walking in and out of the area unbearable.
