TABLE V. SOLUTIONS OF TYPE V. 



Partial volume-molecular concentrations and molecular proportions of 

 KNO3, CaSO«, and Mg(H2POi)2 in 21 solutions all having a calculated 

 osmotic value of approximately 1.00 atm. at 25 °C., but differing (by in- 

 crements of % ) in salt proportions. 



The highest partial volume-molecular concentrations of the salts of this 

 table, that may be employed in the nutrient solutions of this series are 

 those actually given here.

* The solubility of CaS04, 2H2O is approximately .0140 m. Solution R1S6 

 is therefore not possible with an osmotic value of 1.00 atm.
