Concentration, no high value occurs for any set of salt proportions 
in which monopotassium phosphate makes up more than two- 
eighths of the total molecular concentration. 
For the lowest 
total concentration this salt may make up five-eighths of the 
total and a high green-weight value may be produced. 
Furthermore, low values shown in the lower two or three 
triangles of the diagram correspond to relatively low partial 
concentration of magnesium sulphate, and to high ones of cal-
