You Can Increase Your Crop Yields and Profits With 



BEN FRANKLIN Agricultural Gypsum 



Alfalfa at right is from plot treated with Agricultural Gypsum; on 

 K-ind nature left from plot same size untreated. Oregon Exp. Sta. Bulletin 163. 



MORE crops to the acre means more money 

 in your pocket. To increase your crop 

 yields and your profits, you must enrich your 

 soil: you must put 

 back into the soil 

 those elements which 

 previous years' crops 

 have removed. 



There's a 

 Right Way and 

 a Wrong Way 

 to Fertilize 



It's a waste of good 

 time and money to 

 put into your soil 

 plant elements which 

 your soil doesn't 

 need. 



returns most raided 



elements to youi soil by means of the air and the 

 water, but some elements you must put back. 

 These elements are supplied at low cost by Ben 

 Franklin Agricultural Gypsum. 



Ben Franklin Agricultural Gypsum 

 Restores those Elements 

 that Soils Need 



SULPHUR — Sulphur is one important plant 

 element which must be artificially returned to 

 the soil. Sulphur is used up by plants, and 

 sulphur is also leached out of the soil by rain. 

 Ben Franklin Agricultural Gypsum inexpen- 

 sively supplies this vital element, sulphur — 

 and supplies it in the form of sulphur that is 

 immediately and completely available to the 

 crop. 



CALCIUM — Calcium is another element which 

 must be artificially put back in the soil. If 

 the soil lacks it, none of the other plant foods 

 can work properly. And "Ben Franklin" 

 directly supplies calcium. 



NITROGEN — This is another element of which 

 soils rapidly become depleted. But it isn't 

 necessary to buy expensive nitrates for your 

 soil; because science has found that nitrogen 

 can be supplied cheaply, and in ample quanti- 

 ties for all general farming, by two natural 

 methods : 



First, by growing legume crops, such as alfalfa, 

 clover, peas, beans and vetch, with an applica- 

 tion of Ben Franklin Agricultural Gypsum. 

 Legume crops have the property of storing 

 nitrogen in soils through their root "nodules" 

 — and Ben Franklin Agricultural Gypsum 

 greatly increases the growth of legume crops — 

 frequently as much as 500' , — and it also greatly 

 increases the number and size of the root 

 nodules and their power to "fix" nitrogen. 



The second method of restoring nitrogen is by 

 putting stable manure on the soil, and this 

 will be much more beneficial if the manure be 

 treated with Ben 

 Franklin Agricul- 

 tural Gypsum. 



Use 



"Ben Franklin" 

 on Stable 

 Manure 



Nitrogen in manure 

 is liberated in the 

 form of ammonia. It 

 has been estimated 

 that every dollar's 

 worth of Agricultural 

 Gypsum that the 

 farmer puts on his 

 manure pile prevents 



the escape of $2.00 worth of nitrogen. 



POTASH "Ben Franklin" has the property of 

 unlocking the potash present in the soil and 

 setting it to work. The effect is thus the 

 same as if potash were added, and the cost is 

 but a small fraction as much. 



Agricultural Gypsum 

 Is Not Lime 



Do not confuse Agricultural Gypsum and Lime. 

 Lime is not a plant food like Agricultural Gyp- 

 sum, but it is a soil sweetener. Use lime in 

 addition to"Ben Franklin" when your soil is sour. 



Crops on Which "Ben Franklin" 

 Gives Greatest Results 



Legume crops— alfalfa, clover, beans, peas, 

 vetch, etc. Crops of the Mustard Family — mus- 

 tard, turnips, radishes, rape, cabbages, cauli- 

 flower, kale, collards, etc. Other crops — 

 potatoes, tobacco.com, buckwheat, berry bushes. 



Give "Ben Franklin" an opportunity to do for 

 you what it did for the farmers whose letters 

 appear on the back of this circular. 



Broadcast or drill in 300 to 600 pounds per acre.
