The soils of this type are very rich in phosphorus. A soil contain- 

 ing 2200 pounds of phosphorus per two million pounds of soil is re- 

 garded as rich in this element. It will be noted that none of the samples 

 analyzed contain a smaller quantity of phosphorus than this, while the 

 average amount of phosphorus present is 4000 pounds per two million 

 pounds. 



The potassium content is also high. A soil containing 11500 

 pounds of potassium per two million of soil is abundantly supplied with 

 potassium. Only one sample falls below this amount, and many of them 

 greatly exceed it, while the average amount is greater by 1100 pounds. 

 With the proper methods of cultivation the amount of potassium present 

 is sufficient for indefinite periods of time for ordinary general farm 

 crops. 



The amount of nitrogen present is as in all arid soils, somewhat 

 low but by the proper utilization of the ability of legume crops to 

 secure nitrogen from the air this deficiency can easily be corrected in a 

 proper system of agriculture. 



TABLE 2. Phosphorus, Potassium and Nitrogen in Jordan Meadows. 

 (Results expressed as pounds per two million of soil.) 



Average 2900 15800 | 3920 



The composition of the soil of the Jordan Meadows is indicated 

 in Table 2. The conclusions arrived at by a study of the results for 

 the Jordan sandy loam, apply here also. 



TABLE 3. Phosphorus, Potassium and Nitrogen in the Jordan Loam. 

 (Results expressed as pounds per two million of soil.) 



Average 2800 15700" | 2225 



The composition of the Jordan loam is shown in Table 3. This 

 soil like the Jordan Meadows and Jordan sandy loam is well supplied 

 with the elements of plant food.
