DEPARTMENT OF AGRICULTURE 

 TO BUILD POTASH FACTORY 



A plant on a commercial scale will 

 be built by the Department of Agricul- 

 ture for the conduct of experimental 

 work in the production of potash from 

 kelp, an appropriation of $175,000 for 

 the purpose having been made at the 

 last session of Congress. Two loca- 

 tions are under consideration, one 

 near Santa Barbara, the other near 

 Long Beach, California. It is ex- 

 pected that a definite location for 

 the Department's factory will be se- 

 lected shortly and that the work of 

 constructing the plant will begin soon 

 afterward. 



The plans call for a plant capable 

 of handling approximately 200 tons of 

 wet kelp per day. Electric power prob- 

 ably will be used for all mechanical 

 operations, while heat for drying and 

 distillation will be furnished by crude 

 petroleum. The equipment will con- 

 sist of drying kilns, distilling cham- 

 bers, vats, handling machinery, and 

 the necessary buildings to house this 

 apparatus. 



From the 200 tons of kelp used daily 

 about five tons of muriate of potash 

 will be manufactured. The product will 

 be sold and the proceeds turned into 

 the U. S. Treasury. The primary pur- 

 pose of the plant will be to determine 

 the most economical processes for 

 producing potash from kelp and to 

 work out methods for the recovery and 

 utilization of by-products. Numerous 

 methods will be employed experi- 

 mentally in operating the factory 

 with this end in view. For the most 

 part, however, the department will 

 depend on distillation processes. 



The department has decided to lo- 

 cate its experimental factory in 

 southern California because of the 

 combination in this region of an ade- 

 quate supply of kelp and admirable 

 operating conditions. The kelp grows 

 in vast groves in water about GO feet 

 deep along extensive sections of the 

 Pacific coast. For use in the manu- 

 facture of potash it is gathered by 

 ocean-going harvesters which cut the 

 plants beneath the water. In some 

 places the beds extend to the three- 

 mile limit, but in the neighborhoods 

 now being considered by the depart- 

 ment as locations for its factory the 

 groves are much narrower. The plants 

 grow ranidly, and it is believed that 

 little difficulty will be experienced In 

 obtaining an adequate supply of raw 

 material.
