Having thus within their reach a soil-mass several times larger, and aerated 

 to a much greater depth, it is but reasonable to expect that in deep sandy 

 lands plants would do equally well with correspondingly smaller percentage 

 of plant food than would suffice in clay soils, in which the root-range is very 

 much more restricted." 



The following gives an approximate amount of the various ingredients in 

 the upper seven inches of soil per acre.
