1. Effect of hydrogen on soybean root growth in a subsurface solution.
A vertical split-root technique was used to evaluate the effects of pH levels in a subsurface solution compartment on root development of soybean (Glycine max (L.)Merr.). The surface root compartment (12cm) was filled with limed and fertilized soil. Treatments in the solution compartment were seven pH levels (3.7, 4.0, 4.3, 4.6, 4.9, 5.2, and 5.5) with 2uM C
