From the two foregoing examples it is seen that in the case of banana blight, fungi had to be suppressed by bacteriae, but that for pine trees on poor English soils fungi had to be activated for proper tree nutrition.
There is where tree nutrition must begin; whatever is neglected in soils can at best only temporarily be adjusted afterwards.
Maps showed that the blight was worst where there was least lime, and that the chestnut trees died last in Tennessee, where soils are high in lime.
