"...suelos ricos en nutrientes" is a perfect expression! However in the sentence you wrote, it should be singular.
- La deforestación también causa la erosión del material/suelo rico en nutrientes que las plantas necesitan para su crecimiento.
... en la tierra rica en nutrientes 
tierra fértil
( tierra de labor o tierra calma )
