汉译英：只有一句话，关于地理自然环境方面的，急！！有追加

black earth [简明英汉词典]
黑土(一种煤矿石, 捣碎后用于壁画)

其实觉得shelly等都有各自可取之处，但是一直在怀疑直译black earth对不对，所以不敢苟同，dark soil是个人所见，so maybe I 'd like to recommend that:

Here is dark earth plain（不是固定称谓不必用the了吧，毕竟我想这并不是世界闻名的黑土, the earth crust (这就是地壳的意思，不用画蛇添足）steady, soil fertile,and seasons （the four基本多余，有冗余毕竟可以精简)are distinct（喜欢shelly的这个用法，实在高明）.

Here is the black soil plain, smooth crust, the soil is fertile and Four Seasons clear.

Here is the black earth plain, the earth's crust steady, soil fertile,and the four seasons are distinct.

Here is black earth,the crust smooth,rich soil,clearly climate.

This is so-called "black earth" plain.The crust here is stable,the earth is so fertile ,and the four seasons are clear .
你看这么怎么样啊?
