Mr. Grunden notes that tropical forest soil does not have the amount of
nutrients stored in it, as is found in prairie soils. 

Tropical climates provide continuous growth, so there is no need for the
cold climate prairie nutrient storage. The trees of the rainforest will
always be sending the soil under them the continuous supply of organic
matter that will be utilized by soil organisms, and will be supplying soil
organisms with constant supplies of root exudates, in amounts far greater
than prairie grass will give.

Therefore there is no point in comparing the 2 widely differing
situations. I can't imagine why anyone would pit a prairie grass against a
towering legume tree in the Amazon. The climate, soil, rainfall, sunlight,
etc etc are so different, and each provides for its own environment what
is best.
