The composition of the Jordan clay is indicated in Table 4. This 

 is a much poorer type of soil than the others since it contains only half 

 as much phosphorus and nitrogen. Soil of this type is also very compact 

 and difficult to drain. 



TABLE 5. Phosphorus, Potassium and Nitrogen in Soils on Higher 



Lands of Salt Lake County. 

 (Result's expressed as pounds per two million of soil.) 



The results in Table 5 show the composition of the older cultivated 

 lands in the vicinity of Murray. They are given here for comparison. 

 It may be noted that the soils west of Salt Lake are nearly as well sup- 

 plied with nitrogen and potassium and far more abundantly supplied 

 with phosphorus. Sufficient accurate chemical evidence is thus pre- 

 sented upon which to base a confident statement that the soils are well 

 supplied with the chemical elements of fertility. // the salts are per- 

 manently removed by adequate drainage the soil should be converted 

 into fertile farms. Attention should be called to the fact that in the 

 removal of alkali salts by drainage the tilth of the soil may be destroyed 

 temporarily, but this condition can easily be remedied by the introduction 

 of organic matter in the form of barnyard manure or by plowing under 

 a green manure crop.
