there is no reason why you can not do it yourself and save anywhere 

 from two to eight dollars a ton in the operation. 



Mr. Rockhill: I liave been trying to use fertilizers on different crops, 

 and haven't succeeded in getting any benefit from any I have used 

 until this year. I had an experience of sowing fifteen acres of clover 

 in corn stubbles. I used on five acres a mixture, a fertilizer, of five per 

 cent. I went yesterday, after this hot, dry weather, to look over the 

 field. On the next five acres I put nothing; on the third five acres 1 hauled 

 manure, ten loads to the acre. Yesterday I found that the clover where 

 I used the fertilizer has a fine stand, there is a vigorous growth of young 

 clover; where I did not put anything on, the clover is practically l)urned 

 out; where I put the ten loads of manure. I find the clover is not (luilc 

 as good as where I used the fertilizer. About two per cent, is the highest 

 you can buy in this market, of fertilizer. I wanted to use this fertilizer 

 and I could not get it hei'e, so I went to St. Joe for some. It did not 

 have the State Chemist's tag on it. so. I suppose. I violated the law. 



Mr. H. E. Haines: What kind of a fertilizer will barnyard manure, 

 fresh made from stock, and unbleached ashes make? 



Professor Huston: You would be short the phosphate. Your trees 

 would be more liable than others to be attacked with fiingous diseases. 

 With that mixture I would add some acid phosphate. The mixture you 

 speak of has potash and nitrogen enough, but not enough phosphate. 



Mr. Grossman: What time would you apply this to a three-year-old 

 orchard? 



Professor Huston: Whenever it is convenient to plow the land- 

 whenever it is convenient to plow it under. It then fixes it in the soil 

 and it stays there and the tree gets it. 



Mr. Grossman: Is it important to plow it iinder? 



Professor Huston: It is. If you do not, you go to feeding the grass 

 and weeds, and it will also tend to bring the roots too near the top of the 

 ground, aiid it is desirable to get it imder as deeply as you can. If you 

 don't want to do that, you ought to subsitute bone meal, acid phosphate 

 or material that will be more soluble. The bone meal can be sowed on 

 top of the ground, and if you decide not to plow the ground it w5"uld l)e 

 the best thing to do. because it will go down in the ground despite itself. 



Mr. Grossman: Is it difficult to gpt pure potash from the importers? 

 Can the buyer get it directly from the importers? 



Professor Huston: The only people you can get it of are dealers. 

 The importers can not sell it to you.
