PLANT-CHEM SALTS 

A Fresno grower wrote: “I thought you might be interested in a studied record of the 
use of Plant-Chem on four acres of Boysenberries in Fresno County. 
“Planted in February, 1946, no fertilizer was used until September, when we began 
using one pint of Plant-Chem to make a 50-gallon drum of concentrate. This was trickled 
into a stand pipe with a 4-inch discharge pipe from a 6-inch well (pump). 
"T irrigated once a week, Plant-Chem was applied every second irrigation, or once 
_ every two weeks. Trickle of concentrate is regulated to consume the 50-gallon drum in two 
hours. The four acres require 150 gallons, or three pints of salts. 

"There are sixty-three 300-foot rows of sixty plants each. It is problematical if this 
application is giving maximum results, but results are far exceeding most neighborhood 
acreage not using Plant-Chem, as pictures will confirm. 
"This month cf May while berries are forming and ripening, Plant-Chem is being 
applied once a-week (irrigating twice a week). These one-year-old plants now have three- 
months-old new canes five and six feet long comparable to many other two-year-old plants. 
The same can be said of the number and size of berries and the tonnage per acre. We 
have used just 75. pounds in the nine months. 
"For the enclosed check please ship another 25 pounds of Acid tolerant Plant-Chem.”
