D is the correct option.

Explanation:

Taigas are the largest type of coniferous forests on Earth. These forests are spread in Eurasia and North America and mountain regions of Northern Europe. Taigas cover accounts for one-fifth of the total forestland in the world and contains one-half of the world's evergreen forests. These forests have the harshest climate, most of the year the temperature is around minus 50-degree Celsius and can go down to minus 63 degrees. The soil in the taiga is thin and poor in nutrients, the trees found in the taiga are birch, spruce, aspen and willow.

crop rotation kepy different plants in the soil instead of once constintly. when switching out plants you have different nutrients being absorbed at different speeds and different roots growing differently therfore the spoil and water flow have to adapt and carry fresh nutrients to carry the constant changes that were going on in the soil.
