— FERTILIZER ANALYSIS — 



(All chemical analyses of the soil solution given in) 

 (this thesis were made by J. A. Bizzell, Ph.D. ) 



The fertilizer constituent was determined from the 

 samples used for moisture estimation. Nitrogen (NOg) was de- 

 termined for plats 1 to 17; phosphoric acid (PO^) for plats 

 17 to 22; and potassium (K) for plats 22 to 26 inclusive. 

 These were estimated in parts per million (p. p.m.) dry soil. 



** Plat 22 heing a check served for comparison for both P04 

 and K? content.
